Set in the Huai Nam Dang National Park, this hot spring has an average temperature of 176[dg]F (80[dg]C) with steam from the water filling the air. It's a pleasant place to go for a dip, and nearby streams offer cooler water. Several of the spas in town use the water from the hot springs in their treatments. We'd recommend the Pai Hotsprings Spa Resort (84-84/2 Moo 2;, which has rooms starting at 1,000B but you don’t need to be a hotel guest to enjoy a thermal water soak or deep-tissue massages, the latter of which brings sweet relief after hiking.
