There are several local waterfalls, and they are best seen during the rainy season when the water volume is at its highest and the vegetation is lush and green. Cha Ong is the most visited waterfall in the area, and is 18 m high. The rock area behind the waterfall has been eroded away over the centuries by the waterfall, thus allowing you to walk behind the fall. Kan Chang is another fall, which is approximately 7 m in height and empties into a large pool in which it is possible to swim. Ka Tieng is a third waterfall, 10 m tall, in the jungle which also allows swimming, and where you can swim with elephants from the Airavata Elephant Foundation, an organization who is trying to save the last elephants in Ratanakiri. Further out from town are Ou'Sean Lair Waterfall (about 26 km SE) with 4 tiers, Ou'Sensranoh Waterfall (about 9 km SE and 18 m high), Veal Rum Plan stone field (about 14 km N) and another crater lake (about 35 km SE).
