Overview
The river canyons of the Belihuloya area — carved by the highland rivers descending rapidly from the Horton Plains plateau — provide some of the finest canyoneering and river canyon trekking routes in Sri Lanka. The canyons are narrow and dramatic, with the river cutting through layers of rock to create walls of exposed stone, deep plunge pools, and a sequence of small waterfalls that must be descended by abseiling or swimming in the deep green pools below. Canyon trekking here requires technical equipment, experienced guides with canyoneering training, and physical fitness, but it delivers an experience of the highland river landscape from within the canyon that is completely unavailable from the surface trails above. The canyon routes are an emerging adventure activity in the Belihuloya area.
