Rehai, Tengchong

Rehai is a protected geothermal zone in Tengchong featuring numerous hot springs, geysers, and fumaroles that form natural pools across the landscape. Marked pathways guide visitors through this terrain shaped by hot water and rising steam.

This geothermal zone has drawn visitors since ancient times as a rest stop along historical trade routes crossing through Yunnan Province. The springs shaped human movement and settlement in the region for many centuries.

The mineral-rich springs have long been part of local healing traditions, with knowledge about each water source's therapeutic qualities passed down through families in the community.

Plan to spend several hours exploring this area, and wear sturdy shoes since the ground becomes slippery from steam and hot water. Stay on marked paths and pay attention to warning signs to move safely through the geothermal landscape.

At a spot called the Big Boiling Pot, visitors can cook eggs directly in the natural hot spring waters at specific marked locations. This hands-on experience lets you use the geothermal power of the place in an unexpected way.
