Soi Dao Waterfall

Soi Dao Waterfall is a 16-tier waterfall inside Khao Soi Dao Wildlife Sanctuary in Soi Dao District, Chanthaburi Province, eastern Thailand. Situated at the foot of Khao Soi Dao Tai mountain, it is regarded as one of the most scenic waterfalls in eastern Thailand. The falls cascade over moss-covered rocks through evergreen forest with clear pools at lower tiers, notable for its height, forest setting and seasonal butterfly congregations.

Visitors can expect a forested waterfall with 16 distinct tiers cascading down from Khao Soi Dao Tai. The lower 3 tiers are easily accessible via a short forest trail and feature clear pools where wading is possible. Upper tiers require a steep, strenuous hike over uneven rocks and roots through dense evergreen forest. The surroundings are protected wildlife sanctuary forest with streams, boulders, and viewpoints of the mountain. Facilities are basic and centered at the sanctuary checkpoint.

Located within Khao Soi Dao Wildlife Sanctuary, established in 1972 as one of Thailand's early wildlife sanctuaries to protect the evergreen forest watershed of the Khao Soi Dao mountain range. The waterfall has been a protected natural landmark within the sanctuary since its establishment.
