Dur Tshachu is one of Bhutan's most remote and rewarding natural hot spring destinations, accessible only by a challenging multi-day trek through the Lunana district of northern Bhutan — the highest permanently inhabited region in the Himalayas — where mildly sulphurous water emerges from the ancient Himalayan basement near glaciated peaks at extreme altitude. The trek to Dur, through one of Bhutan's most spectacular and least-visited wilderness landscapes, passes through yak herding settlements, ancient Buddhist temples, and vast moraines left by retreating glaciers. The springs at Dur, where exhausted trekkers soak in warm mineral water surrounded by 7,000-metre peaks and infinite Himalayan sky, represent one of the most extraordinary and hard-won hot spring experiences anywhere on Earth.
Insider tip — Dur Tshachu is Bhutan's most remote accessible hot spring, requiring a multi-day trek through the Jigme Dorji National Park to reach the high-altitude meadows near the Tibetan border. The spring sits at roughly 3,600 meters, and the combination of altitude and geothermal warmth creates an extraordinary soaking experience beneath Himalayan peaks. It is a traditional gathering point for nomadic yak herders who descend from the high pastures in autumn.
