Tengchong Hot Springs: Geothermal Wonders of Yunnan

Tengchong, in western Yunnan near the Myanmar border, sits on a volcanic field that produces abundant hot springs. The geothermal activity creates boiling pools, steam vents, and therapeutic waters that have made Tengchong a major destination for hot spring tourism.

Rehai (Hot Sea) Geothermal Area

The Rehai area is the most concentrated geothermal field in China. Boiling pools bubble at over 90°C; steam vents hiss continuously; geysers erupt periodically. Locals cook eggs in the near-boiling water. The landscape is otherworldly, with mineral deposits coloring the ground yellow, orange, and white.

Hot Spring Resorts

Dozens of hot spring resorts surround Tengchong, offering pools at various temperatures. The waters are rich in sulfur, silica, and other minerals. Many visitors come specifically for therapeutic soaks, believing the waters help with arthritis, skin conditions, and fatigue. The resorts range from basic to luxurious.

Volcanic Geopark

The Tengchong Volcanic Geopark preserves the evidence of past eruptions. Lava flows, volcanic cones, and crater lakes dot the landscape. The most recent eruption was about 5,000 years ago. Hiking trails lead to viewpoints and into lava caves.

Diehe River Waterfall

The Diehe River Waterfall, about 30 meters high, is unusual for its location on a volcanic plateau. The waterfall is surrounded by tropical vegetation, creating a lush contrast to the barren geothermal areas.

Beihai Wetland

The Beihai Wetland, a high-altitude marsh, offers boat rides through reed beds and past water birds. The wetland is a peaceful contrast to the dramatic geothermal areas. Walking trails circle the marsh.

Getting There

Tengchong has an airport with flights from Kunming. The hot spring areas are scattered; a car or tour is useful. Plan 2–3 days for the geothermal attractions and surrounding sights. The hot springs are enjoyable year-round, though winter is especially popular.
