The Snowman Trek, which passes along the border of Tiber and Bhutan, in the height of the Himalayas, is considered on the hardest treks in the world. Less than 50 hikers complete the 180 mile long, 21-day long trek each year. The path passes through some remote and incredibly pristine parts of the Himalayan mountain range, crossing through snow-capped passes, isolated villages, and scores of yak herders on the move.
