Chet Si Waterfall

Chet Si Waterfall, also known as Nam Tok Chet Si or Seven Colours Waterfall, is a seasonal forest waterfall located inside Phu Wua Wildlife Sanctuary in Seka District, Bueng Kan Province, northeastern Thailand. The waterfall flows over sandstone terraces forming shallow pools and is noted for sunlight creating rainbow-like colours on the rocks and water. Surrounded by dry dipterocarp and mixed deciduous forest, it is most impressive during the rainy season when water volume is high.
