This is a superb 8-day trek for strong walkers. Starting from Paro it goes into northern Bhutan to the land of yak-herders and to the base of Mount Cholomhari (7,316 meters / 24,000 feet), which is the most holy mountain for the Bhutanese. From there the trek goes on to remote Lingshi Dzong which once guarded the frontier with Tibet . This trek offers fabulous views of the mountains including Chomolhari, Jitchu Draake and Tsheringkhang mountains besides stunning Himalayan scenery and exceptional flora. You will encounter many yak-herders with their hairy wards and their camps but few villages. The maximum altitude gained is 4,900 meters (16,000 feet).
