Bhutan’s 24-day Snowman Trek is rightly touted as one of the hardest in the world. The journey crosses ten Himalayan mountain passes and tops out at 17,591 feet. But there are plenty of shorter and easier routes, including a ten-day trek to 11th-century fortress ruins at the base camp of 23,995-foot Mount Jomolhari and a multi-day trip through the Sakteng Wildlife Sanctuary, a protected area that’s supposedly home to the migo, or yeti. For a one-day adventure, start at 13,084-foot-high Chele La Pass, then hike a four-mile loop to the cliff-hanging Kila Goempa, home to 30 nuns. It’s hairy terrain, but Guides of Bhutan has you covered; its trekking team includes Sither Tshering, a graduate of India’s Himalayan Mountaineering Institute who has led Reinhold Messner.
