Thmatboey is an isolated village located in Kulen Promtep Wildlife Sanctuary in the Northern Plains of Cambodia. The site supports globally important breeding populations of two critically endangered Ibis species: the Giant Ibis and the White-shouldered Ibis, in the only known nesting site of this species.
Visitors can walk through a rich eco-system of open woodlands, seasonally-inundated grasslands, deciduous dipterocarp forest and scattered wetlands. Between the 9th and 15th centuries A.D. the Khmer Empire based at Angkor dominated the landscape and many features can still be seen today.
