Namphu Ron Fang is a natural hot spring near the town of Fang in Chiang Mai Province, northern Thailand, where geothermally heated sulfurous waters bubble to the surface in a lush tropical setting. The spring is part of a geothermal zone associated with the active tectonics of northern Thailand, and local Lanna communities have used its waters for traditional bathing and healing practices for generations. Visitors can enjoy the open-air thermal pools surrounded by dense vegetation and distant mountain views characteristic of the Chiang Mai highlands.
Insider tip — Namphu Ron Fang — Fang Hot Spring — is a geothermal site in the Fang District of northern Chiang Mai Province, situated in a mountain-valley corridor where the Shan Plateau meets the northern tip of Thailand's volcanic geology. The springs erupt as powerful geysers and bubbling mud pools in a forested park, with the main jets shooting water several meters into the air. Sulfurous steam rises continuously across the thermal field, creating a moody atmosphere amplified by the surrounding teak woodland. Visitors soak in channel pools fed by cooled spring water, and locals sell eggs boiled in the natural hot pools at the park entrance.
