Tengchong Hot Spring Yunnan

Tengchong Hot Spring, in the border city of Tengchong in western Yunnan Province near Myanmar, is set within China's most volcanically active geothermal zone — the Tengchong volcanic field, where over 90 volcanoes and hundreds of hydrothermal vents create an extraordinary landscape of steaming fumaroles, boiling mud pools, and cascading thermal waterfalls in the subtropical forests of the Gaoligong mountain range. The calcium-rich thermal waters, heated by the volcanic activity of the Indian-Eurasian plate collision zone, emerge at temperatures ranging from comfortable bathing temperatures to near boiling at the most active vents in the Rehai (Hot Sea) National Park. Tengchong's unique combination of volcanic thermal geology, the ancient Silk Road jade trade heritage that made it one of Yunnan's wealthiest cities, and the extraordinary biodiversity of the Gaoligong mountains — one of the world's most important conservation zones for Himalayan flora and fauna — makes it one of China's most scientifically and culturally exceptional hot spring destinations.
