The fourth largest waterfall by volume in the world. The widest waterfall in the world at 10km wide. The largest waterfall in Southeast Asia. The falls holds a number of records and sees the Mekong River plunge 21 metres at the border of Laos and Cambodia. Despite its size, this impressive waterfall is little-known in Cambodia due to its remote location.
Also called Khone Phapheng Falls from the Laos side of the border, the falls is downstream of the popular 4,000 islands area of Laos.
You can reach here from Stung Treng town as a stop on the journey towards Kampong Thom or Preah Vihear.
You can even swim in the water above the falls. The rocks create a number of safe calm pools around the edge of the river. The water is clean and cool.
The best to visit is around December when water levels dropped enough to reveal the rocks, but there is still a sufficient quantity of water otherwise. In wet season, the torrent of water is so large that it covers the whole area, while in dry season the flow is much less spectacular.
