Page introduction
The Duer Hot Spring Trek is a demanding wilderness journey from Bumthang to remote hot springs deep in northern mountain country. The route follows forest, rivers and high pasture through Gorsum, Lungsum and Tsochenchen, crosses the Juli La area and reaches Duer Tsachu before retracing its course. The reward is profound isolation and the chance to soak in traditionally valued medicinal hot springs.

Difficulty and safety
Long walking days, remote terrain, cold camps and a high point near 4,700 metres justify the hard grade. Evacuation can be difficult. Participants need strong endurance, prior multi-day trekking experience, suitable insurance and a conservative approach to altitude. The itinerary may change because of snow, damaged trails, river conditions or pack-animal access.
Frequently asked questions
Are the hot springs developed like a spa? No. Expect a remote natural and culturally important bathing area with basic conditions rather than resort facilities.
Is this suitable as a first Himalayan trek? Generally no. A shorter Bhutan trek or previous high-altitude camping experience is better preparation.
