Chae Son National Park in Lampang province, northern Thailand, is a protected natural area centred on a remarkable thermal spring complex where bicarbonate-rich water at around 75°C feeds a series of natural stream pools and developed bathing facilities in a pristine tropical forest setting. The park's thermal springs, waterfalls, and diverse mountain forest make it one of Thailand's most complete natural attractions, blending geothermal phenomena with exceptional biodiversity. The cool mountain air of the Lampang highlands and the park's relatively uncrowded atmosphere make Chae Son a refreshing alternative to Thailand's busier thermal destinations.
