Some of the last unexplored places on the planet can only be reached by kayak, with explorers making a first descent on rivers that are wild and untamed. The video below is an example of such an expedition through the Tawang Valley located the remote Arunachal Pradesh in India. The journey was expected to take two weeks, with the team going completely self supported over 130 miles of river that, up until that point, had never been seen by man. Along the way, they experienced Class V rapids, deep canyons, perilous rocks, and plenty of adventure.
