6–8 hours
Suitable for people with basic fitness: able to follow paddling commands, enter/exit a raft, and comfortable in moving water.
Charge upriver from Bentota to Kitulgala for an accessible day of white-water on the Kelani. Expect busy rapids, rainforest banks, and a route steeped in cinematic lore — all on a well-run, private-day tour.
The Kelani River pushes and sighs as your raft threads a corridor cut through rainforest and rubber estates. Early light slides across the current, turning the water a greenish burnish; birds flicker through the canopy and the distant staccato of a village radio mixes with the river’s voice. By the time the van from Bentota has finished the coastal run and climbs into the wet-zone hills, the air has thickened with humidity and expectation — this is where Sri Lanka’s monsoon-fed waterways strain themselves into ridable whitewater.

Rafting is at its most predictable from January–March; heavy monsoon rains can make sections unsafe and tours will be canceled.
Use sandals with straps or old trainers you don’t mind getting soaked — flip-flops can wash off during swims.
Bring a waterproof case or dry bag for phones and cameras; many great shots happen on the raft.
Carry a refillable bottle and eat a light breakfast; bottled water is provided but bring snacks if you need steady energy.
Kitulgala’s Kelani River briefly entered global attention when a section was used as a filming location for The Bridge on the River Kwai; fragments of concrete foundations remain near the river.
The wet-zone rainforest here is sensitive to erosion; guides emphasize staying on trails and minimizing plastic use — bring reusable bottles and dispose of waste with your guide.
Dries fast after getting splashed or taking a swim in the river.
