Tatai Waterfall which is in the province of Koh Kong is a large rocky cascade situated in the middle of a dense jungle meeting the Tatai River. This waterfall flows all year round and it is possible for one to swim in it in the summer season. During the summer season it has natural pools below the waterfall because of less flow of water. Walking along the ridge is also possible in summer. The waterfall gets its water from the Cardamom Mountains. The water is clear because it has less human settlements nearby. The waterfall can be reached by road or boat.
