Established in a remote corner of the Cardamom Mountains, one of Southeast Asia’s best preserved rainforests, the Wildlife Release Station aims to reintroduce trafficked or captive animals to the wild. Run by Wildlife Alliance, it is possible to stay the night in their basic jungle lodge and head out on patrol with the hardy rangers based out here. Resident animals include leopard cats, sun bears, pangolins, gibbons, macaques and more. All the visitor fees are ploughed back into the conservation work of Wildlife Alliance.
