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.
The conservation area runs its own basic on-site camping ground and fan-cooled chalets, bookable directly with Yayasan Sabah — grid power runs only 5pm to 11pm as part of a sustainability policy.
