This free-entry hot spring is located in the Chiang Mai area of Thailand. Its sulfurous water reaches around 40°C and feeds an open-air pool suited to wild bathing.
Insider tip — These free-entry hot springs north of Chiang Mai city sit within the volcanic geothermal corridor of the Chiang Rai highlands at 40°C, with a characteristic sulfur steam visible in cooler months. The site is maintained as a public resource with simple concrete pools and a small car park, making it accessible to budget travelers and locals alike. Nearby fruit orchards of lychee and longan trees frame the bathing area in a decidedly pastoral setting. Early morning visits reward bathers with a mist-shrouded atmosphere as thermal vapors rise against the backdrop of forested hills.
