Khao Soi Dao Wildlife Sanctuary

Khao Soi Dao Wildlife Sanctuary is a large protected forest area in Soi Dao District, Chanthaburi Province, eastern Thailand near the Cambodian border. Established in 1972, it covers approximately 745 square kilometres of evergreen and deciduous forest centered on Khao Soi Dao Nuea and Khao Soi Dao Tai, the highest peaks in eastern Thailand. It is notable for its biodiversity, including Asian elephants, and for the 16-tier Khao Soi Dao Waterfall located within its boundaries.

Visitors can expect a remote, forested mountain landscape with dense evergreen forest, streams and the multi-tiered Khao Soi Dao Waterfall accessible via a nature trail. The sanctuary headquarters area has a visitor centre and trails for nature study and birdwatching. Wildlife sightings are possible but not guaranteed. Facilities are basic and focused on conservation and nature education. Access to the summit peaks requires permission and a ranger guide.
