The Kelani Ganga at Kitulgala runs Grade 3 to 4 rapids through a gorge where the rainforest comes down to the water on both sides. The Bridge on the River Kwai was filmed here in 1957 and the original bridge supports are still visible in the river. About 12 kilometres of water, certified operators and safety kayakers throughout. Finished by noon, with the afternoon free.
Horton Plains
The roof of Sri Lanka - a plateau that simply ends at World’s End
At 2,100 metres, Horton Plains is the highest and flattest landscape in Sri Lanka. The 9-kilometre circular trail passes through montane cloud forest to World’s End, a sheer escarpment where the plateau simply stops and the plains 900 metres below open out on a clear morning. Baker’s Falls on the return route. The dawn departure is non-negotiable.
