Another fun activity to try in Bhutan would be the Traditional Hot Stone Bath.
The bathwater is called Menchu/ Smenchu or medicinal water; it is made by boiling Artemisia leaves with fresh river water. The process includes hot river stones, which are roasted in the fire until they give out a gleaming red look. The water temperature is increased by inserting the hot stones up a wood chute which is connected to the wooden tub containing medicinal water.
The holes in the wooden chute allow water to be heated quickly, this prevents any burn or injury chances; it is very safe. In the culture, the stones are supposed to possess healing powers that they transmit in mineral form into the water. After a long day having fun outdoors, you can end it relaxing in Menchu water while enjoying hot drinks. You can add on scrub and massage if you need it. This would be an excellent way to release all the tension and stress and regain your calm and composure for the next thrilling day traveling and seeing Bhutan.
