Dur Tsachu

After long-ago battles, Bhutanese soldiers recovered from their wounds by soaking in tsachu, or hot springs. The tsachus' curative powers were so highly regarded that people would trek for weeks to bathe in them to treat joint and muscle pain, headaches and a host of other ailments.

While the Duer Tsachu is more accessible than it once was, it still requires a tough four-day trek from the nearest road head along a trail known as the Duer Hot Springs Trek. Those who make it out here will be rewarded with steaming, clear water flowing into wooden tubs covered with a simple wooden shelter and a nearby campsite — a welcome chance to refresh and revive feet and muscles aching from the walk.
