Khao Chamao Waterfall
An eight-tier waterfall in Rayong whose pools hold hundreds of protected mountain carp that swarm around waders.
Updated 28 August 2026
Khao Chamao falls in eight tiers down a forested slope, with a trail following the stream from the headquarters up past pool after pool - the first two or three tiers are an easy walk and the upper ones need more effort. The fish are the reason it is known: the pools hold large numbers of pla phluang, soro brook carp, protected within the park and entirely unafraid, and standing in the shallow water means being surrounded by them. Feeding is discouraged, which distinguishes this from the more commercial fish-feeding sites. The park covers about 84 square kilometres of hill forest and holds a small elephant population, which occasionally comes into conflict with surrounding orchards. Flow is seasonal, running strongest from July into November and much thinner in the hot season. Rocks along the stream are slippery and the upper trail involves scrambling.
What you'll find
