Snowman Trek in Bhutan is one of the most beautiful treks in the whole Himalayas. Billed as the most difficult trek in the world due to altitude, duration and distance, far more people climb Mount Everest in Nepal than completing this alpine quest. Many return incomplete due to altitude sickness. The trek goes on northern Bhutan along the border with Tibet crossing thirteen Himalayan mountain passes some as high as 5000m. You will have spectacular mountain views of Jumolhari, Jichu Drake, Masangang, Tiger Mountain and Gangkar Puensum and other conspicuous peaks along the norther border.
