Sikkim has many hot springs known for their medicinal and therapeutic value. The most accessible are the ones located at Phurchachu (Reshi), Borong, Ralong, and Yumesamdong. All these hot springs (locals often refer to them as ‘cha chu’) have high sulphur content and are located near riverbanks. The average temperature of the water in these hot springs is 50 degree centigrade. Just like the state's peaks, lakes, caves, these hot springs are also considered holy.
