Snowman Trek

The Snowman Trek is often billed as the world's toughest trek — 350 km across the Bhutanese Himalaya from Paro in the west to Bumthang in central Bhutan, crossing 11 passes above 4,500 m and five above 5,000 m through the remote Lunana region, one of the most isolated inhabited valleys on the planet. More people have summited Everest than have completed the Snowman; the trek attempts a Himalayan traverse at extreme altitude over 25+ days where weather closure is normal rather than exceptional.

The route starts on the Jhomolhari trekking trail (one of Bhutan's most popular shorter treks) and continues east. After Laya at 3,840 m the route enters the restricted Lunana region — a high yak-herding valley with semi-nomadic populations and dramatic views of Gangkar Puensum (7,570 m, the world's highest unclimbed peak by government decree). The crux is the section between Lunana and Bumthang, where Sinchey La at 5,005 m is the highest of a chain of high passes. From Sinchey the route drops gradually through the Tibetan-influenced eastern Bhutanese highlands to Bumthang's monastery valley. The shorter Laya-Gasa version (about 14 days, finishing at Gasa hot springs) is the standard Plan B if Snowman's higher section is impassable.

Snowman runs only October through early November — the brief weather window between summer monsoon and winter snowfall. Even in season, around half of attempts are cancelled by snow on the higher passes; pack a full week's buffer and accept the trek may end at Laya. All Bhutan trekking must be arranged through a licensed Bhutanese operator (no independent trekking allowed); the country's tourism policy requires a $100/day Sustainable Development Fee plus operator costs of $250–400/day. Total package runs $10,000–15,000 per person for the full 25-day trek, including porter teams, yaks, cooks, and oxygen for the high camps.
