There are a few modest but picturesque waterfalls within easy reach of Banlung, easily combined into a half-day trip along with a visit to Yeak Laom lake. The falls at Chha Ong, around 8km northwest of Banlung, are the largest, the river flowing through lush jungle before plunging 30m into a gorge. The pool at the base is deep enough to swim in, and daring souls can climb onto a ledge behind the curtain of water.
Southwest of Banlung, hidden in a bamboo-clad valley, are the Ka Chhang falls, just 10m high, but impressive after rain and with a pool for taking a dip. Nearby are the small and similar Katieng falls. You can hop on an elephant ride here ($10/hr) for a trip around the falls, although the animals are often overworked.
