Gasa

Gasa is the northernmost and least populated district of Bhutan, a mountain valley below the Tibetan border whose hot springs have drawn Bhutanese pilgrims for centuries. The tsachu at the bottom of the gorge holds several stone pools of different temperatures and fills through the winter with families who come for weeks at a time to treat joint complaints. Above the springs a small round dzong sits on a spur. Gasa is the trailhead for the Laya trek and the Snowman, generally considered the hardest trek in the world. The road up from Punakha is rough and takes most of a day.
