Plai Poo Hot Spring is a natural geothermal source in Thailand, located in the highland or forested landscape of one of Thailand's geothermally active regions where naturally heated mineral waters emerge from the earth and are used by local communities for bathing and traditional healing practices. The spring provides naturally heated mineral water at temperatures comfortable for bathing, and its relatively undeveloped setting preserves the authentic character of a community hot spring that has served local residents and occasional visitors for generations. Thailand's numerous natural hot springs like Plai Poo reflect the country's position in a geothermally active region of Southeast Asia, where tectonic forces produce geothermal resources across the northern and southern highland regions.
Insider tip — Plai Poo Hot Spring in Phang Nga province is a lesser-known geothermal site where natural mineral water surfaces through jungle-covered karst terrain at a steady temperature. The site sees far fewer visitors than the famous Khlong Thom springs further south, offering a more intimate and secluded bathing experience. The mineral-rich water leaves skin feeling refreshed after soaking. The surrounding Phang Nga countryside of rubber plantations and limestone hills makes the journey there as scenic as the destination.
