Regions

Sabah · Sarawak · Brunei · Kalimantan

Borneo is split between three countries, and where you go decides what you're likely to see. Sabah is the easiest introduction — orangutans, Bornean elephants and proboscis monkeys all within a week's travel. Sarawak trades that for limestone caves, Rafflesia and longhouse culture upriver. Brunei protects some of the last untouched primary rainforest on the island. Kalimantan is by far the largest share and holds most of the wild orangutan population, but takes longer to reach. Choose a region below for the reserves, rivers and national parks in it, and the species you're most likely to see at each.

Why Sabah

Sabah packs an unusual range of habitat into a small area — lowland dipterocarp rainforest at Danum Valley, the river floodplain of the Kinabatangan, montane cloud forest above 3,000m on Mount Kinabalu, and a chain of protected reserves connecting them. Distances are short and the roads are good, which is why a single week here can turn up orangutans, Bornean elephants, proboscis monkeys, clouded leopards and hornbills within a few days of each other.

Deramakot Forest Reserve

Sustainable forest

A 55,000-hectare forest reserve that has been logged under strict sustainable-forestry certification since the 1990s — proof that timber production and serious wildlife density aren't mutually exclusive. The wide, well-maintained network of old logging roads is what makes it exceptional: night drives along them are why Deramakot is the most famous place in the world to look for a Sunda clouded leopard. Visitor numbers are deliberately kept low, with licensed operators running small groups deep inside the reserve rather than at its edges.

Best for: night drives, Clouded Leopard, small carnivores

Kinabatangan

River safari

Sabah's longest river, and the easiest place in Borneo to see a genuinely wide range of wildlife without a long trek — boat safaris glide along the water's edge through floodplain forest where animals concentrate on the narrow remaining strip of habitat between the river and encroaching oil palm. That concentration effect is what makes it so productive: proboscis monkeys, Bornean elephants, orangutans and estuarine crocodiles are all seen here with a regularity most other sites can't match, even though the surrounding landscape is far more disturbed than places like Danum Valley or Maliau.

Best for: easy access, Proboscis Monkeys, river safaris
Sukau Greenview — Borneo wildlife, book, free download, jungle tour, Sukau Greenview tour, Sukau Greenview trip

Sukau Greenview

Affordable riverside lodge

A more affordable riverside lodge in Sukau village on the Lower Kinabatangan that still takes searching for wildlife seriously, with great guides who know the river. It is a single-storey, 14-room property on the village's riverfront road, a short walk from the jetties where the morning and afternoon boat trips and night cruises depart, which makes it one of the best-value ways to spend real time on the water. Booking sites rate it around 8.8/10, and guests praise the location for river and jungle trips. The river is a strong place to look for the Borneo Big Five.

Best for: Affordable Sukau base, serious wildlife guiding, great guides
Borneo Nature Lodge — Borneo wildlife, book, free download, jungle tour, Borneo Nature Lodge tour, Borneo Nature Lodge trip

Borneo Nature Lodge

Mid-range riverside lodge

A mid-range, eco-minded lodge on the bank of the Kinabatangan River in Sukau, with its own jetty, restaurant and boardwalk, and a favourite with serious birders and mammalwatchers because of the flexibility to arrange extended cruises beyond the standard outings. The lodge runs its own river cruises, which past guests single out as the highlight of a stay, and it markets an eco-friendly approach — guests can even cycle for an hour to power their room's fans and lights. A newer sister property, Borneo Nature Lodge 2, is listed separately in Sukau, so check which one you are booking.

Best for: Favourite with birders and mammalwatchers, flexible extended cruises, own jetty
Kinabatangan Wetlands Resort — Borneo wildlife, book, free download, jungle tour, Kinabatangan Wetlands Resort tour, Kinabatangan Wetlands Resort trip

Kinabatangan Wetlands Resort

Luxury wetland resort

One of the most luxurious lodges on the river, set deep in the Lower Kinabatangan wetlands within the Kinabatangan Wildlife Sanctuary and deliberately tucked away from the cluster of lodges along the main river. The surroundings are mangrove and nipah palm, and the chalets, dining room and library are linked by raised walkways, so you can watch the forest between outings. Activities are mostly boat trips out looking for wildlife, with orangutans, macaques, pygmy elephants and Rhinoceros Hornbills among the animals listed for the area.

Best for: Luxury wetland setting, raised walkways, mangrove and nipah forest
Osman's Homestay — Borneo wildlife, book, free download, jungle tour, Osman's Homestay tour, Osman's Homestay trip

Osman's Homestay

Family homestay & guide

A family-run homestay in Sukau led by Osman, a veteran Kinabatangan boatman and guide whom guests repeatedly praise for finding animals others miss; reviewers also mention that he has guided wildlife documentary crews, including David Attenborough's. His trips are strongly mammal-focused — pygmy elephants, proboscis monkeys and orangutans — and many guests have seen Sunda Clouded Leopard with him, alongside rarities such as Flat-headed Cat and Helmeted Hornbill, though sightings always vary from trip to trip. Crocodiles are a regular sight on the river, and photos from Osman's own page also show owls and a Black-and-red Broadbill, so bring binoculars and a strong torch for the night cruises. With so many photogenic species along the river, it also makes a good base for wildlife photography.

Best for: Expert local guide, Clouded Leopard sightings, mammal-rich river trips, home cooking
Tanjung Bulat Jungle Camp — Borneo wildlife, book, free download, jungle tour, Tanjung Bulat Jungle Camp tour, Tanjung Bulat Jungle Camp trip

Tanjung Bulat Jungle Camp

Community jungle camp

A community-run eco camp on the Kinabatangan River, and the only camp on its oxbow lake — so when you stay, you have the whole oxbow to yourselves, well away from any village and from the boat traffic of the busier lodge stretches. Local jungle people run it, and listings describe it as engaged in forest rehabilitation and community projects. The usual package is two days and one night or three days and two nights, with river cruises, night walks and meals included. Visitors report darters, monitor lizards and egrets, and the river holds crocodiles, so swimming is not allowed.

Best for: The only camp on its oxbow lake, the whole oxbow to yourselves, community-run
Beluran Safaris — Borneo wildlife, book, free download, jungle tour, Beluran Safaris tour, Beluran Safaris trip

Beluran Safaris

Emerging / remote

Beluran Safaris runs night drives, early-morning and afternoon 4WD drives, and boat cruises on the Segaliud Lokan river through Segaliud-Lokan Forest Reserve, a sustainably managed forest in Beluran district, central Sabah, roughly 1h45 from Sandakan airport. Entry is through a private plantation, so the tracks see far fewer visitors than better-known sites like Deramakot. The appeal is the range of small nocturnal carnivores — Sunda leopard cat, marbled cat, Malay civet and other civets, Sunda stink badger — alongside Sunda pangolin, slow loris, Sunda colugo and owls after dark, with Bornean orangutan, maroon langur, hornbills and the odd Bornean elephant by day. Trips run as 3 days/2 nights or 4 days/3 nights, operated by 1StopBorneo Wildlife.

Best for: mammal watching, night drives, off-the-beaten-path
Tabin Wildlife Reserve — Borneo wildlife, book, free download, jungle tour, Tabin Wildlife Reserve tour, Tabin Wildlife Reserve trip

Tabin Wildlife Reserve

Lowland

Sabah's largest wildlife reserve at over 120,000 hectares, protecting lowland forest east of Lahad Datu that would otherwise sit surrounded by oil palm plantations. Its defining feature is a natural mud volcano — a mineral-rich seep that draws elephants, bearded pigs and other mammals in to drink and wallow, making it one of the most dependable wildlife-viewing spots in the reserve. Night drives along the old logging roads regularly turn up civets, owls and, with luck, clouded leopards.

Best for: Elephants, mud volcano wildlife, night drives
Danum Valley — Borneo wildlife, book, free download, jungle tour, Danum Valley tour, Danum Valley trip

Danum Valley

Pristine forest

One of the most complete stretches of lowland dipterocarp rainforest left standing anywhere — 438 square kilometres that has never been commercially logged, giving it a density and height of old-growth canopy that's rare even within Borneo. It's been a hub for tropical ecology research since the 1980s, including a long-running Sunda clouded leopard project, and the resulting body of knowledge means guides here can find and interpret wildlife other sites simply can't. A 27-metre-high canopy walkway puts you at eye level with hornbills and gibbons rather than craning upward from the forest floor.

Best for: Clouded Leopard, Orangutans, primary-forest birding
Danum Valley Field Centre — Borneo wildlife, book, free download, jungle tour, Danum Valley Field Centre tour, Danum Valley Field Centre trip

Danum Valley Field Centre

Research station

The working heart of the Danum Valley Conservation Area — 438 square kilometres of primary lowland dipterocarp forest, thought to be over 130 million years old, that Yayasan Sabah's trustees chose to leave permanently unlogged back in 1980. The Field Centre opened in 1986 to support that decision with science, and has since become one of the foremost tropical rainforest research stations in the Old World tropics. Accommodation is functional rather than comfortable — resthouse and hostel blocks, generator power until 11pm — but the trade-off is direct trail access into forest that has never been touched, with a pre-dawn trek to the Bukit Atur viewpoint among the highlights.

Best for: Primary-forest research trails, Bukit Atur sunrise, serious naturalists
Borneo Rainforest Lodge — Borneo wildlife, book, free download, jungle tour, Borneo Rainforest Lodge tour, Borneo Rainforest Lodge trip

Borneo Rainforest Lodge

Upmarket lodge

Beside the Danum River inside the Conservation Area, 11 kilometres from the Field Centre and reachable only by permitted 4WD — Borneo Rainforest Lodge was the area's first dedicated hospitality site when it opened in 1994, and has since become one of the most decorated eco-resorts in Southeast Asia. Guest numbers are capped at around 60 a night to keep pressure on the surrounding primary forest low, and everything runs full-board with small guided groups. A 360-metre canopy walkway reaching 27 metres up puts you level with hornbills and gibbons rather than craning from the forest floor, and the wider programme takes in river tubing, a pre-dawn Bukit Atur sunrise trek, and Coffin Cliff, an old Orang Sungai burial site cut into the rock above the river.

Best for: Canopy walkway, riverside chalets, capped guest numbers
Infapro — Borneo wildlife, book, free download, jungle tour, Infapro tour, Infapro trip

Infapro

Forest restoration

Eleven kilometres from the Danum Valley Field Centre along the road into the Conservation Area, Infapro — the Innoprise-FACE Foundation Rainforest Rehabilitation Project — has been replanting selectively logged forest with indigenous dipterocarps since 1992. Around 11,864 hectares have now been rehabilitated across nine planting contracts, making it the largest forest restoration project under Yayasan Sabah, and a widely cited model for tropical reforestation elsewhere in the region. Accommodation sits between the Field Centre's austerity and the Lodge's comfort — resthouses with hot showers and 24-hour electricity — and the surrounding mosaic of restored, remnant and open habitat draws a distinctive mix of wildlife moving between Ulu Segama and Danum proper.

Best for: Restoration project, mosaic habitat, lower-cost base
Langom — Borneo wildlife, book, free download, jungle tour, Langom tour, Langom trip

Langom

New research station

Langom sits in the buffer zone of the Danum Valley Conservation Area, close enough to the Field Centre that guests can use its trail network for daytime walking and birding, while Langom's own 4WD safari roads add the kind of night-drive terrain that made Deramakot's reputation — both from the same base. For anyone stuck weighing up Danum against Deramakot, Langom is worth putting on the shortlist as an answer rather than a compromise. Completed in 2024 and officially launched in June 2025 by Yayasan Sabah with the Sabah Forestry Department and Universiti Malaysia Sabah, funded under the 12th Malaysia Plan, it's still building a track record — but what's come out of it so far has been good. Marbled Cat sightings have been frequent enough to note, this is turning into a reliable spot for Bornean Bristlehead, one of the harder endemics to pin down elsewhere, and orangutan encounters are regular. The forest mosaic around the station adds range of its own — primary Danum-age rainforest, regenerating INFAPRO-style restoration forest, and a riparian corridor along the river — and the ridge-top access road is turning into one of the better stretches in the area for nocturnal, arboreal species. It shares Danum's forest, without the Field Centre's crowds.

Best for: Marbled Cat, Bornean Bristlehead, orangutan, close to Field Centre trails, low visitor numbers
Kinabalu Park — Borneo wildlife, book, free download, jungle tour, Kinabalu Park tour, Kinabalu Park trip

Kinabalu Park

Montane / UNESCO

Borneo's first UNESCO World Heritage Site, built around Mount Kinabalu — at 4,095m the highest peak between the Himalayas and New Guinea. The mountain's huge elevation range packs half a dozen distinct vegetation zones into a single trail system, from lowland rainforest through mossy cloud forest to stunted alpine scrub near the granite summit plateau. That range in altitude and cooler climate supports plants and birds found nowhere in Sabah's lowlands — including several pitcher plant species that grow only on this mountain.

Best for: montane birds, pitcher plants, cool-climate trekking
Lupa Masa — Borneo wildlife, book, free download, jungle tour, Lupa Masa tour, Lupa Masa trip

Lupa Masa

Herping / jungle camp

Lupa Masa began in 2010, when Tom Hewitt rented a patch of the Kampung Poring forest that people locally knew as Mangawong, after the river running past it. The name it goes by now came from his own remark that every time he came here he forgot all his problems — lupa masa, Malay for forget time. The camp sits thirty minutes on foot from Poring Hot Springs and metres from the Kinabalu Park boundary at around 550m, in lowland forest right where it begins grading into lower montane — a completely different band from the cloud forest 19km away at park headquarters. Guided night walks of two to three hours are what most visitors come for, and the herping is what has earned the camp a reputation well beyond Sabah: red-headed krait and dragon snake are the headline finds, alongside pit vipers, cat snakes, bronzebacks and a long list of frogs. Days go to the clear Kinabalu river ten metres from camp, the waterfall seven minutes downstream, and birding along the trails — and Rafflesia occasionally blooms on site, though catching one open is luck rather than planning. Accommodation is deliberately basic: six bamboo and reclaimed-wood shelters open to the forest under mosquito nets, around 25 guests at capacity, no WiFi, intermittent power, and nights that drop to 15°C.

Best for: night herping, Red-headed Krait, Dragon Snake, frogs
Trusan Sugut (Turusan Sugut) — Borneo wildlife, book, free download, jungle tour, Trusan Sugut (Turusan Sugut) tour, Trusan Sugut (Turusan Sugut) trip

Trusan Sugut (Turusan Sugut)

Emerging / remote

An 8,680-hectare Class I forest reserve wedged between the Beluran and Paitan districts, upgraded to full protection status only in 2014 — meaning it's still one of the least-visited forest blocks in Sabah despite genuinely strong wildlife. Access is by longboat along the Sugut River or 4x4 track, which alone keeps casual visitor numbers low. Surveys here have logged over 330 bird species alongside orangutans, banteng and proboscis monkeys, making it a serious option for anyone wanting Kinabatangan-level wildlife without the crowds.

Best for: Orangutans, Banteng, Proboscis Monkeys, 330+ bird species
Maliau Basin — Borneo wildlife, book, free download, jungle tour, Maliau Basin tour, Maliau Basin trip

Maliau Basin

Wilderness

Known as the "Lost World of Sabah" for good reason — a roughly circular, bowl-shaped basin ringed by steep escarpments up to 1,675m high, so isolated that its interior wasn't properly surveyed until the 1980s. The rim acts as a natural barrier that has kept the forest inside almost entirely free of human disturbance, logging or hunting pressure. Reaching the waterfalls and camps inside requires a multi-day trek, which is exactly why species density and endemism remain so high — this is one of the few places left where a clouded leopard sighting doesn't feel like a fluke.

Best for: multi-day trekking, high endemism, waterfalls
Imbak Canyon — Borneo wildlife, book, free download, jungle tour, Imbak Canyon tour, Imbak Canyon trip

Imbak Canyon

Conservation area

A rugged sandstone canyon reserve that, together with Danum Valley and Maliau Basin, anchors the "Heart of Sabah" conservation corridor — a connected block of protected forest large enough to sustain wide-ranging species like clouded leopards and elephants long-term. Its canyon terrain and 300-metre cliffs create microhabitats not found in the surrounding lowlands, and because access is limited to guided research and expedition trips, the forest here sees a fraction of the visitor traffic of its more famous neighbours.

Best for: research-grade biodiversity, guided expeditions
Gomantong Caves — Borneo wildlife, book, free download, jungle tour, Gomantong Caves tour, Gomantong Caves trip

Gomantong Caves

Limestone caves

A pair of vast limestone caves rising out of the Kinabatangan floodplain, long harvested for edible birds' nests — a trade that dates back centuries and still continues under licence today. At dusk, millions of wrinkle-lipped free-tailed bats stream out of the cave mouth in a spiralling column that can take the better part of an hour to fully empty, timed almost exactly opposite the swiftlets returning to roost. The cave floor below supports a guano ecosystem of its own, home to specialised invertebrates and the cave racers that hunt them.

Best for: bat exodus at dusk, cave swiftlets, easy walking trails
Trus Madi — Borneo wildlife, book, free download, jungle tour, Trus Madi tour, Trus Madi trip

Trus Madi

Mountain

Malaysia's second-highest peak at 2,642m, just 70km from Kota Kinabalu but a world apart in visitor numbers — there's no cable car or paved summit trail here, just a steep, often muddy climb through five distinct vegetation zones. That relative obscurity is the draw: montane specialists like Whitehead's trogon and Whitehead's broadbill that are hit-or-miss on the crowded trails of Kinabalu Park are seen here with better odds, and the mountain's pitcher plants and invertebrates include species found on Trus Madi and almost nowhere else.

Best for: challenging trekking, endemic plants, montane birds
Tawau Hills Park — Borneo wildlife, book, free download, jungle tour, Tawau Hills Park tour, Tawau Hills Park trip

Tawau Hills Park

Lowland / day-trip

A rainforest park a short drive from Tawau town, built around a set of natural hot springs and waterfalls that make it one of the most accessible lowland forest experiences in southeastern Sabah — no long boat ride or multi-day trek required. It also protects some of the tallest tropical trees in the world: several dipterocarps here exceed 80m, among the tallest tropical rainforest trees ever measured. The combination of easy access and genuine old-growth forest makes it a solid budget option for wildlife that's usually reserved for far more remote sites.

Best for: day hikes, hot springs, accessible rainforest
Sepilok — Borneo wildlife, book, free download, jungle tour, Sepilok tour, Sepilok trip

Sepilok

Sanctuaries & night walks

Three protected sites share the Kabili-Sepilok Forest Reserve outside Sandakan, making this one of the most reliable places in Borneo to see its signature mammals up close without a long trek. The Sepilok Orangutan Rehabilitation Centre rescues and reintroduces orphaned orangutans, with viewing platforms at feeding time putting you within metres of them; next door, the Bornean Sun Bear Conservation Centre shelters Borneo's smallest and least-studied bear. Tying the reserve together is the Rainforest Discovery Centre, whose suspended canopy walkway and observation tower lift you into the treetop canopy by day, while its real highlight comes after dark — guided night walks along lit boardwalks that turn up tarsiers, slow lorises and civets rarely seen in daylight. Long-tailed macaques are a near-constant presence along the walkways themselves.

Best for: Orangutan & Sun Bear centres, night walks, canopy walkway
Telupid and Kampung Bestaria — Borneo wildlife, book, free download, jungle tour, Telupid and Kampung Bestaria tour, Telupid and Kampung Bestaria trip

Telupid and Kampung Bestaria

Bird hide

A cluster of community-run bird hides in central Sabah built on years of patient habituation work, and the most dependable place on Earth to see a Bornean peacock-pheasant — a bird that spent most of the twentieth century as a ghost in Sabah, missed even by camera-trap surveys running tens of thousands of trap-nights. The main hide is managed by a cooperative formed by residents of nearby Kampung Bestaria, alongside the Ulu Telupid Birding Centre. A second hide at a small wetland pond targets the critically endangered straw-headed bulbul, and a third, reached by a longer trek, gives access to blue-banded pitta. Reaching the peacock-pheasant hide means a short walk through forest at the end of a dirt road, in position well before dawn, and often a full day of quiet waiting.

Best for: Bornean Peacock-Pheasant, Straw-headed Bulbul, community-run hides
Kinabatangan Bird Hide — Borneo wildlife, book, free download, jungle tour, Kinabatangan Bird Hide tour, Kinabatangan Bird Hide trip

Kinabatangan Bird Hide

Bird hide

A giant pitta hide in the Pin Supu Forest Reserve, reached from the village of Batu Puteh on the lower Kinabatangan. Unlike the habituated hides at Telupid and Trus Madi, this one leans on the quality of the surrounding floodplain forest — at over 4,600 hectares, Pin Supu is the largest protected reserve in the Lower Kinabatangan floodplain, looked after for more than two decades by the community cooperative KOPEL in partnership with the Sabah Forestry Department. Batu Puteh was named a UN World Tourism Organization Best Tourism Village in 2021. The wider forest and the oxbow-lake eco camp nearby add pittas, four hornbill species and Storm's stork along the riverbanks.

Best for: Giant Pitta, Crested Fireback, Sabah Partridge, a deep understorey birding checklist
Taliwas River Conservation Area — Borneo wildlife, book, free download, jungle tour, Taliwas River Conservation Area tour, Taliwas River Conservation Area trip

Taliwas River Conservation Area

Bird hide

Roughly 9,500 hectares of lowland and unusual ultramafic forest east of Lahad Datu, managed by Yayasan Sabah and long known mainly as a camping and recreation spot. Its hide targets arguably the hardest bird on the island to see: the Bornean ground-cuckoo, a large, secretive, pheasant-like cuckoo with iridescent purple-green wings that forages on the forest floor, often trailing ant swarms or bearded pigs, and is far more often heard than seen. Recent visiting groups have been connecting with it. Accessible forest trails, a resident river system and ranger support make it a straightforward add-on for birders already in the Lahad Datu area.

Best for: Bornean Ground-Cuckoo, ultramafic forest, river trails
Mount Silam — Borneo wildlife, book, free download, jungle tour, Mount Silam tour, Mount Silam trip

Mount Silam

Bird hide

Rising to 884 metres directly above Lahad Datu and Darvel Bay, Mount Silam is one of Sabah's more overlooked birding sites. Its open canopy and varied terrain run from lowland forest up to a distinctive heath forest near the summit, and the hide here has become a reliable stop for blue-banded pitta, rufous-tailed shama and orange-breasted trogon. The wider mountain has produced Bornean bristlehead, helmeted hornbill, white-necked babbler and scarlet-breasted flowerpecker. Close enough to Lahad Datu to pair easily with Taliwas or Tabin.

Best for: Blue-banded Pitta, heath forest, easy access from Lahad Datu
Sayap Substation — Borneo wildlife, book, free download, jungle tour, Sayap Substation tour, Sayap Substation trip

Sayap Substation

Squirrels, herping, small carnivores & night walks

A quieter, lower-elevation substation on the north side of Kinabalu Park, about 40km from park HQ as the crow flies but a 2.5-hour drive by road. Sitting around 1,000m, well below the cloud forest at HQ, it protects some of the most beautiful forest in Sabah and has become known among visiting mammal-watchers for an exceptional range of squirrels — a disused road climbing from the office, with one large fruiting tree about 200m up, is the go-to spot. Camera trapping by 1StopBorneo has also turned up Hose's civet and Kinabalu ferret badger here, and night walks (now limited to two hours under tightened park rules) regularly produce binturong and masked palm civet. It's just as good for herping and insects — Bornean horned frog and Sabah Pit Viper are both quite common. Most trails are steep, narrow and slippery, so the old road is the easier option for casual visitors.

Best for: squirrel diversity, night walks for civets, herping (Bornean Horned Frog, Sabah Pit Viper), camera-trap rarities (Hose's Civet, Kinabalu Ferret Badger)
Trus Madi Bird Hide — Borneo wildlife, book, free download, jungle tour, Trus Madi Bird Hide tour, Trus Madi Bird Hide trip

Trus Madi Bird Hide

Bird hide

Two habituated feeding hides just below the Kupu-Kupu Gate on the Tambunan side of Trus Madi Forest Reserve, at around 1,300m. They're the only realistic way to see the famously shy Bulwer's pheasant, which visits several times a day, along with crested, red-breasted and crimson-headed partridge and a few very tame Bornean banded pittas. Entry is capped at 12 people a day and booked through the reserve.

Best for: Bulwer's Pheasant, Crested/Red-breasted/Crimson-headed Partridge, tame Bornean Banded Pittas

Borneo Entomology Camp

Insect macro / night walks

Also known as Trus Madi Entomology Camp or Borneo Jungle Girl Camp, sitting at around 1,170m inside the Trus Madi Conservation Area — a Class 1 fully protected forest reserve founded in 1986 by Philip Chew and family after they pooled their savings to buy and regenerate the land, with an operating permit granted in 2006. Built specifically around invertebrate macro photography rather than the usual mammal or bird checklist, guided night walks turn up stick insects, katydids, mantises and the mountain's frogs. Accommodation runs to 60 guests across several room types, some en-suite with balconies, with a communal dining area and 24-hour electricity.

Best for: insect macro photography, guided night walks, montane invertebrates
Inikea — Borneo wildlife, book, free download, jungle tour, Inikea tour, Inikea trip

Inikea

Forest restoration

The INIKEA Rainforest Rehabilitation Project, a 6-hour drive from Sukau in the Kinabatangan — 18,500 hectares of forest badly burned by El Niño-driven wildfires in the early 1980s and since replanted with native dipterocarps using funding from IKEA's owners, on a similar model to Infapro at Danum. Despite the scarred history, 1StopBorneo Wildlife's guided groups here have racked up a strong big-cat record: of roughly 25 visiting groups, marbled cat has turned up once and Sunda clouded leopard four times, alongside regular western tarsier, binturong, Sunda stink badger and a range of civets on night drives.

Best for: Sunda Clouded Leopard, night-drive civets, forest restoration

Selingan Island (Turtle Islands)

Turtle nesting island

The main visitor island of Turtle Islands Park off Sandakan, where green turtles nest on the beach almost every night of the year and hawksbills less frequently. Rangers escort small groups to watch a female nest and lay, then release that night's hatchlings into the sea — one of the most dependable wildlife spectacles in Sabah, reached by a short boat ride from Sandakan. It's worth arriving early: visiting birders have used the daylight hours on the island for some incidental birding, turning up Nicobar pigeon among the more expected seabirds, and flying foxes are often seen streaming over at dusk.

Best for: nightly turtle nesting, hatchling release, ranger-led viewing, incidental island birding

Why Sarawak

Malaysia's largest state trades Sabah's mountains for limestone karst and cave systems — Gunung Mulu alone holds one of the largest cave chambers on Earth and a nightly exodus of millions of bats. The rainforests hold their own records too: Lambir Hills has logged more tree species per hectare than almost anywhere else studied, and Gunung Gading protects Rafflesia, the world's largest flower. Add proboscis monkeys on the coast at Bako and Iban longhouse culture upriver at Batang Ai, and it's a very different kind of Borneo trip to Sabah's.

Bako National Park — Borneo wildlife, book, free download, jungle tour, Bako National Park tour, Bako National Park trip

Bako National Park

Coastal / peninsula

Malaysia's oldest national park, gazetted in 1957, occupying a small sandstone peninsula just outside Kuching — compact enough to explore in a day, yet packed with an unusual range of habitat for its size: mangrove, kerangas heath forest, and dramatic wave-cut sea stacks along the coast. That habitat variety is why it punches so far above its size for wildlife, and it remains one of the most reliable places anywhere to see proboscis monkeys, whose population here is used to a regular human presence around the park headquarters.

Best for: Proboscis Monkeys, sea stacks, short accessible trails
Niah National Park — Borneo wildlife, book, free download, jungle tour, Niah National Park tour, Niah National Park trip

Niah National Park

Limestone caves

Centred on the Niah Caves, one of the most important archaeological sites in Southeast Asia — excavations here uncovered the "Deep Skull," among the earliest modern human remains found anywhere in the region, dated to around 40,000 years old. The Great Cave itself is still very much alive: its ceiling holds huge colonies of swiftlets and bats whose nests have been harvested here for generations, a trade you can still see in progress on the cave floor. A raised plank walk makes the caves and surrounding forest easy to explore without a guide.

Best for: cave archaeology, swiftlet and bat colonies, plank walk trails

Gunung Mulu National Park

Montane / UNESCO caves

A UNESCO World Heritage Site built around one of the largest and most explored cave systems on Earth, including the Sarawak Chamber — the single largest known cave chamber by area in the world — and Deer Cave, whose nightly exodus of several million wrinkle-lipped bats is one of the great wildlife spectacles in Borneo. Above ground, the park's razor-sharp limestone pinnacles and karst forest support their own distinct flora, reachable via a demanding multi-day trek that keeps the pinnacles themselves relatively untouched despite the park's fame.

Best for: show caves, nightly bat exodus, pinnacles trekking
Semenggoh Wildlife Centre — Borneo wildlife, book, free download, jungle tour, Semenggoh Wildlife Centre tour, Semenggoh Wildlife Centre trip

Semenggoh Wildlife Centre

Orangutan rehabilitation

An orangutan rehabilitation centre 24km from Kuching, where semi-wild orangutans released back into the surrounding forest still return to a feeding platform on a semi-predictable schedule (April to November gives the best odds, since fruiting forest in the wetter months can keep them away) — the closest thing in Borneo to a guaranteed orangutan sighting without days of trekking. Some of the animals here are second-generation, born wild in the surrounding forest to mothers who were themselves rehabilitated, a small but real conservation success story visible in a single visit.

Best for: Orangutan feeding sessions, easy access from Kuching
Batang Ai — Borneo wildlife, book, free download, jungle tour, Batang Ai tour, Batang Ai trip

Batang Ai

Orangutan / dam lake

Centred on a vast hydroelectric lake in southern Sarawak near the Kalimantan border, Batang Ai National Park and the forest surrounding its lake are considered one of the most important strongholds for wild, genetically distinct orangutans in Sarawak. Reaching the park means a boat journey across the lake itself, passing traditional Iban longhouse communities who have lived along its forested shores for generations — a rare combination of serious wildlife habitat and living indigenous culture in the same trip.

Best for: wild Orangutans, Iban longhouse culture, boat access

Gunung Gading National Park

Rafflesia reserve

A compact park near Lundu in western Sarawak built around a single extraordinary attraction: Rafflesia, the world's largest flower, whose blooms here can exceed 80cm across and last only a few days once open. Because blooming is unpredictable and short-lived, the park maintains a bloom hotline so visitors can time their trip — a level of species-specific infrastructure few other parks bother with. Away from the flowers, short accessible trails lead to waterfalls and natural swimming pools through lowland rainforest.

A compact park near Miri that holds a genuine scientific record: a long-term 52-hectare research plot here has recorded over 1,200 tree species, one of the highest tree diversities per hectare ever measured anywhere on the planet. That botanical richness supports a proportionally rich understorey and canopy fauna, though most visitors come for the more immediate appeal of accessible waterfalls and swimming holes reachable on well-marked trails through hill dipterocarp forest.

Best for: waterfalls, exceptional tree diversity, accessible trails

Maludam

Peat swamp / red banded langur

Sarawak's second-largest national park at 432 km², gazetted in 2000 and protecting the largest single patch of peat swamp forest left in Sarawak and Brunei. It's the world's only site with a viable population of the red banded langur, one of Borneo's rarest and most striking primates, and holds one of only around five viable proboscis monkey populations left in the state, alongside a significant number of silvered langurs. Visits go through the park office in Kampong Maludam — reached by vehicle ferry at Triso, then road — where you register and hire a boat to cruise the narrow, tannin-stained peat swamp waterways.

Best for: Red Banded Langur (only viable population anywhere), Proboscis Monkey, peat swamp forest

Tanjung Datu

Coastal rainforest / marine park

One of Sarawak's smallest and most remote national parks, tucked into the far western tip of the state near the Kalimantan border, where rainforest runs down to sand beaches and fringing reef. Access is by a short boat ride from the village of Telok Melano — a new road from Sematan to Telok Melano opened in 2018 and made the trip easier, though the final leg into the park is still by water and the sea is often too rough to cross during the November–February monsoon. Low visitor numbers and no direct road access have kept both the forest and the surrounding marine park in good condition, and green turtles nest on the park's beaches from April to September.

Best for: remote coastal rainforest, fringing reef, green turtle nesting (Apr–Sep), boat-only access

Why Brunei

Oil wealth meant Brunei never had to log its rainforest for revenue, and the result is one of the highest proportions of untouched primary forest left anywhere on the island. Ulu Temburong National Park is the centrepiece — reachable only by longboat, with a canopy walkway suspended above forest that's barely been touched. It's a small footprint next to Sabah or Sarawak, but what's there is about as pristine as Borneo gets.

Ulu Temburong National Park

Pristine rainforest

Known as the "Green Jewel of Brunei" — largely untouched lowland and hill rainforest reached by a road journey from Bandar Seri Begawan (around an hour, crossing the Sultan Haji Omar Ali Saifuddien bridge) followed by a longboat leg up the Temburong River, a combination that keeps visitor numbers naturally low. Its best-known feature is an aluminium canopy walkway that climbs to around 50m, high enough to put you above the canopy rather than just inside it, with views across an unbroken expanse of forest that's increasingly rare anywhere in Borneo. Brunei's oil wealth has meant comparatively little pressure to log or convert this forest, which is a large part of why it's stayed so intact.

Tasek Merimbun

Wetland / lake

Brunei's largest natural freshwater lake and an ASEAN Heritage Park — a blackwater lake, its tea-dark, tannin-stained water ringed by peat swamp forest that floods and recedes with the seasons. It sees a fraction of the visitors that Ulu Temburong does, which makes it a good option for wetland birding and a quieter, more contemplative alternative to the canopy-walkway crowds — boat trips across the lake are the main way to explore it, drifting past hornbills and waterbirds working the forest edge.

Ulu Brunei

Night drives / village edges & rainforest

The interior of Belait District, reached via Jalan Labi from Bandar Seri Begawan — a mix of village outskirts, rubber and fruit gardens, and rainforest parks that 1StopBorneo Wildlife has been quietly exploring by night drive, in Brunei's low season for tourism generally. Kampong Teraja, an Iban longhouse further along the same road, adds a waterfall trek (a roughly 40-minute uphill hike to Wasai Teraja's plunge pool) as a daytime pairing with the night drives. On a January 2025 joint trip, Mike Gordon (Adventure Alternative Borneo) and Shavez Cheema (1StopBorneo Wildlife) logged nine species across two drives — banded civet, numerous palm civets, greater mouse-deer, leopard cat, flying foxes on a fruiting ficus, brown wood-owl and a bronzeback snake on the first night; red leaf monkeys, two binturongs, lesser mouse-deer, buffy fish-owl, nightjars and two slow lorises on the second. Shavez's team has previously recorded clouded leopard and sun bear twice each, marbled cat three times, flat-headed cat twice, plus yellow-throated marten, pangolins, moon rat and tufted ground squirrel here — genuine potential for Brunei's harder carnivores, still very much under-explored.

Why Kalimantan

The Indonesian side of the island is by far its largest — roughly three-quarters of Borneo's landmass — and holds the majority of the wild orangutan population as a result. Tanjung Puting is the best-known access point, with klotok riverboats gliding past feeding platforms built up by decades of research at Camp Leakey. Further north, Kutai and the seasonally flooded lake system at Danau Sentarum cover terrain few visitors ever reach, from Mahakam River swamp forest to blackwater floodplains that transform completely between wet and dry season.

Orangutan / river safari

Home to Camp Leakey, the orangutan research and rehabilitation site founded by Birutė Galdikas in 1971 and still active today — one of the longest-running great ape studies anywhere in the world. Reaching the park means flying into Pangkalan Bun and driving to the river town of Kumai, since the park itself is accessible only by water from there. Multi-day safaris aboard traditional wooden klotok houseboats, sleeping on deck under mosquito nets, travel blackwater rivers through peat swamp forest between feeding stations — Camp Leakey and Pondok Tanggui among them — making this one of the most immersive and reliably productive orangutan-watching trips anywhere in Borneo.

Kutai National Park

Lowland forest

Lowland dipterocarp rainforest in East Kalimantan that has survived a rougher history than most protected areas in this guide — major fires in the 1980s and 1990s, along with illegal logging and encroachment, badly damaged large sections of the park. Reaching it means flying into Balikpapan's Sepinggan Airport, travelling on to Samarinda, then taking a boat along the Mahakam River to the park itself. Despite its history, Kutai remains one of the few places left in the province with a genuinely wild orangutan population, and the forest's slow recovery is itself a case study in how tropical rainforest regenerates after disturbance.

Best for: wild Orangutans, lowland dipterocarp forest

Danau Sentarum National Park

Floodplain wetland

A vast seasonal floodplain lake system in West Kalimantan, connected to the Kapuas River and dramatically transformed by the annual flood cycle — during the wet season the lakes can expand many times over, turning forest into open water and back again within months. That flood pulse drives an unusually productive freshwater fishery that local communities have relied on for generations, and the same nutrient-rich waters support proboscis monkeys, waterbirds and the Malaysian false gharial along the forested lake margins.
