Chae Son National Park Hot Springs in the Lampang province of northern Thailand emerge within one of Thailand's finest national parks — a landscape of pristine teak forest, bamboo groves and granite mountains crossed by clear mountain streams and inhabited by sun bears, gibbons and a remarkable diversity of bird species. The sulphurous springs, which emerge at temperatures of 70–80°C, are channelled into bathing pools of different temperatures within the park's thermal area, and the contrast between the intense forest environment and the geothermal heat creates an experience of wild, elemental beauty. The overnight camping facilities within Chae Son National Park allow visitors to combine thermal bathing with forest immersion in one of northern Thailand's most unspoiled natural landscapes. The drive through the Chae Son valley from Lampang city passes through some of the most beautiful teak forest scenery in Thailand.
Insider tip — Chae Son National Park shelters one of northern Thailand's most dramatic geothermal fields in a forested valley of Lampang Province, where sulfurous water at over 70 degrees Celsius jets from multiple vents and cascades down travertine terraces into progressively cooler bathing pools. Park vendors sell wooden egg baskets to boil food directly in the spring vents, a tradition that doubles as a cooking lesson. The surrounding mixed deciduous forest hosts gibbons and hornbills audible during early morning bathing sessions before the day-trippers arrive from Lampang city. Visit from November to February for cool-season mist in the forest and the most comfortable outdoor soaking conditions.
