Tong Mai Changqing Wenchi is located in Nyingchi, in the Tibet Autonomous Region of China. This sulfurous spring, warm at around 42°C, feeds an indoor bath and an outdoor pool set amid the Himalayan landscape.
Insider tip — Tong Mai Changqing Wenchi is a geothermal field in the densely forested Nyingchi Prefecture of eastern Tibet, where the Indo-Australian tectonic plate drives intense volcanic activity. Multiple vents and pools dot a meadow clearing, with sulfurous steam rising into the pristine mountain air. The Yarlung Tsangpo River canyon is nearby, offering world-class scenery for trekkers. Access requires a Tibet Travel Permit; the remoteness guarantees a genuinely wild soaking experience far from any tourist infrastructure.
