Dá Nà Sì Wēnqián is a sulfurous spring in Dengqen, Tibet, at high altitude. Water at 38°C (pH 6.5) feeds an indoor bath and an outdoor rotenburo-style bath.
Insider tip — Da Na Si Wenquan is a remote geothermal spring in the highlands of eastern Tibet near Dengqen, where sulfurous waters emerge at altitude among dramatic Tibetan plateau landscapes. The spring sits at elevation above 3,500 meters, and the combination of thin air and mineral warmth creates a distinctly otherworldly bathing experience. Nomadic Tibetan communities have used these waters for traditional healing purposes for generations. Visitors should acclimatize to altitude for at least 24 hours before indulging in prolonged bathing.
