Nam Phu Ron San Kamphaeng — 'San Kamphaeng Hot Spring' — is a well-known geothermal spring complex in the San Kamphaeng area of Chiang Mai province in northern Thailand, where naturally hot mineral water emerges at temperatures up to 100 degrees Celsius from a cluster of vents and pools in a beautifully landscaped natural park. The springs, among the most visited in Thailand, are a popular day trip from Chiang Mai city, offering visitors the experience of naturally boiling spring vents alongside cooler bathing pools where the water has been temperature-moderated for comfortable immersion. The site is particularly beloved for the sulphurous hot pools where locals and tourists soak together in the Thai tradition of communal hot spring bathing.
Insider tip — Located in the foothills east of Chiang Mai, these northern Thai thermal springs are fed by a volcanic fault system that runs through the Ping River basin. The sulfurous waters reach boiling at the main vent but are channeled into comfortable bathing pools nearby. Locals traditionally cook eggs in the hottest pools — a custom visitors are encouraged to try. The forested park setting provides welcome shade in the tropical heat.
