The hikes in Bhutan range from easy to very difficult with some of the world’s highest snow-capped peaks. Then there is also a sense of relaxation, a form of onsen, a raging hot water bath made with natural stones. The stones are heated either by fire, and or by gas, then placed into the tub’s sub compartment according to how hot you want it. The more the stones, the more the heat. Be aware that the hot stones deliver instant heat, a scalding effect to the body.
