River Runners and Cave Walkers: A 48‑Hour Adrenaline Loop from Bentota to Kithulgala
48 hours of river rapids, village trails, and a cave that whispers human history
By the time the minivan peels off the coastal ribbon of Bentota and snakes inland, the air thickens with green. Rubber plantations give way to a forest that smells like wet wood and citrus; the road narrows, and then you are beside the Kelani River, which moves as if it has a destination of its own—at times a polite guide, at others a dare. Here, in Kithulgala, the river runs quick and honest, and the hills around it hide caves worn by older weather and older hands. Over two days you’ll paddle, pedal, and step into both the current and a quiet archaeology of place.
Trail Wisdom
Respect the River’s Mood
River levels change rapidly—ask guides about current difficulty and follow briefings; higher water means bigger rapids and fewer exposed rocks.
Footwear for Wet and Rocky Terrain
Wear closed-toe water shoes or lightweight approach shoes with good tread to protect toes on river rocks and cave trails.
Protect Your Electronics
Use a small dry bag or waterproof case for phones and cameras—expect splashes and the occasional full soak.
Hydrate and Pace Yourself
Sri Lankan humidity makes exertion feel harder—carry water and take the guide’s rest breaks during cycling and hiking sections.

Conservation Note
Local guides rely on the river for livelihood—pack out trash, avoid single‑use plastics, and follow guide instructions to minimize erosion and disturbance to riverbanks.
Belilena and surrounding caves are part of Sri Lanka’s deep prehistory, with archaeological finds in the region indicating human occupation tens of thousands of years ago.
