Lèng Khin waterfall is situated in Oreang district, a few kilometers from Sen Monorom, the capital of Mondulkiri province in Cambodge. This cascade sits within a landscape of dense mountain forest, bordered by pastures and rice paddies worked by local communities, primarily Bunong. With a drop that can exceed 25 meters during the rainy season, it ranks among the region's highest waterfalls.

Why visit Lèng Khin

Lèng Khin draws visitors for three concrete reasons. First, its height: few waterfalls in Mondulkiri exceed 20 meters, and this one ranks at the top regionally. Second, its dense forest setting, which maintains a shaded, cool atmosphere even during hot season. Third, its moderate visitor traffic compared to the better-known Bousra waterfall: Lèng Khin remains a still-undiscovered stop on the Mondulkiri waterfall circuit.

The site suits both a brief stop and a full day spent combining forest trekking or visiting a neighboring village.

Waterfall characteristics

Lèng Khin's dimensions vary significantly by season:

• Dry season: the cascade measures 22 to 23 meters in height and roughly 7 meters in width. Water flow is reduced, the water separates into fine streams, and the lower pool remains accessible for swimming.
• Rainy season: the waterfall reaches 28 meters in height and 8 meters in width. The water flow becomes powerful, spray is significant, and swimming at the base of the fall is generally not recommended.

The calmer downstream pool offers a refreshing pause. The forest surrounding the site is home to discreet wildlife—birds and butterflies—and dense vegetation typical of Mondulkiri's plateaus.

When to visit

Choosing your timing depends on what you're looking for.

• December to March (dry season): ideal conditions for swimming and site access. The cascade is less dramatic but water flow remains respectable, and trails are passable without difficulty.
• June to October (rainy season): the waterfall reaches peak visual impact, but access trails may become muddy and slippery. Swimming at the base is not recommended.
• April-May and November: transition periods, generally passable with a good balance between water flow and accessibility.

How to get there

The logical starting point is Sen Monorom. A road connects the town to Oreang district, where the waterfall is located. Travel is typically by car, motorcycle, or daily rental tuk-tuk. Plan for a good hour of travel time from Sen Monorom depending on trail conditions.

The final kilometers pass through rural areas where signage is limited. Hiring a local driver or guide is recommended, especially since many itineraries combine Lèng Khin with other waterfalls or visits to Mondulkiri coffee plantations.

Practical information

• Gear: closed-toe shoes with good grip (surroundings are wet and slippery), swimsuit, towel, insect repellent, water, and snacks.
• Swimming: possible in the dry season in the lower pool; avoid the base of the waterfall during periods of heavy flow.
• Visit duration: plan for 1 to 2 hours on site to enjoy the location, longer if you combine with a picnic or hike.
• Entrance fee: a modest entrance fee may be requested locally.
• Safety: do not venture onto rocks immediately near the waterfall, especially during the rainy season.

Combining activities in Mondulkiri

Lèng Khin fits well into a regional circuit. Several neighboring waterfalls merit a visit:

• Bousra: the province's most famous waterfall, accessible and developed.
• Chrey Thom: a more discreet cascade in similar forest surroundings.
• Lèng Tao: another waterfall on the plateau, often paired with Lèng Khin on local itineraries.

Beyond waterfalls, the region offers encounters with Bunong communities, ethical elephant-back rides, and visits to the coffee plantations that have made the plateau famous.
