Bou Sra Waterfall at a Glance#
Bou Sra Waterfall is a multi-tiered waterfall in Mondulkiri province, eastern Cambodia, and is one of the province’s most visited natural attractions.
The site is valued for its tall cascades set in remnant rainforest and open viewing ledges above and below the drop. Walks and informal paths lead to several viewpoints where visitors can photograph the falls and the surrounding forest.
The waterfall is a natural feature long known to local communities and has become a regional tourist destination in recent decades as Mondulkiri developed modest visitor facilities. There are no major constructed works at the falls beyond basic viewing platforms and trails.
The falls sit in eastern Mondulkiri province, within driving distance of the provincial capital Sen Monorom, and are set among rolling hills and patches of evergreen forest typical of the area.
- Access: Located in eastern Mondulkiri province, reachable from the provincial capital Sen Monorom by local roads and short forest tracks.
- Best time to visit: Best visited during the dry season when paths are firmer and viewpoints above the falls are easier to reach.
Exploring Bou Sra Waterfall#
Bou Sra is the largest waterfall in Cambodia and a popular place for swimming and picnicking. It falls in three separate tiers: the first drops more than 9 m and the second roughly double that. For most visitors these two tiers are the whole experience, and many never learn there is a third.
The water runs faster at the third tier and the forest there is dense enough to make the approach impractical. There are no maintained trails to it, and locals warn that dangerous wildlife makes the visit unwise; whether or not that is so, few venture that far.
The upper two tiers are reached by a sealed road, making the falls easy to get to by moto, hire car or motorbike. From Sen Monorom the trip takes less than an hour.
Best Time to Visit Bou Sra Waterfall#
Late dry season offers reliable access; wet season provides the most impressive waterfall volume.
