The largest of the waterfalls surrounding Ban Lung is the 65-foot (20-m) Cha Ong Waterfall; while not ideal for swimming, it is an impressive sight to behold, and those who wish to cool off can walk close enough to enjoy a shower from the torrential cascade.

While the waterfall is less impressive in the dry season, the road to the falls is much easier to navigate during that time.

Cha Ong Waterfall is enjoyable year round, though in the rainy season, particularly August and September, you may have difficulty navigating the muddy roads. December through March has the nicest weather, best roads, and still a decent amount of water to enjoy the falls.

Cha Ong Waterfall is located six miles (9 km) northwest of Ban Lung Town in the scenic northeast of Cambodia. The best way to get there is from Ban Lung with a motorbike (with good directions or a map), motodop taxi with a local guide, or a minivan from your hotel. There are signs for the falls, but that doesn’t mean you are guaranteed not to get lost or injured, particularly as the road is bumpy when dry and slippery when wet.
