Discover the natural gem of Tengchong Zaohe thermal spring and spa, nestled in Yunnan Province, China. This bicarbonatée and siliceuse water source has been a haven for relaxation and rejuvenation for centuries. Soak in the warm waters and let the stresses of modern life melt away. The site's unique geology creates a tranquil atmosphere that will leave you feeling refreshed and renewed.
Insider tip — Tengchong Zaohe is a boiling spring cluster within the Rehai geothermal field in western Yunnan, where water saturated with silica and sulfur erupts at near-boiling temperatures. The calcium-silica terraces and steaming fumaroles resemble a miniature Yellowstone set against tropical vegetation. Bathing is done in prepared pools at the edges of the field where the water has cooled to a safe temperature. Arrive early morning to see the steam clouds at their most spectacular against the mountain backdrop.
