Few rafting rivers in the world can match the thundering course of the rivers of Nepal originating from the snow meltdown of the Himalayan terrain. The rivers gush through the twisted canyons, winding through calm valleys where small settlements are perched on the banks, taming out only as they spill out into the Indian plains to merge with the Ganges. A river-trip is one of the best ways to explore the typical cross-section of the country's natural as well as the ethno-culture heritage with massive doses of adrenaline buzz on our world-class white-water thrills. An extreme sport popular in Europe, canyoing is now available in Nepal. It involves abseiling, jumping, sliding, climbing along waterfalls and steep cliffs to deep pools, giving the canyoneer the freedom to explore beautiful under-water landscape.
