Saline Hot Springs is a chloride-rich geothermal bathing site in Thailand, where naturally heated water emerges enriched with dissolved salt minerals from the geological formations through which it passes before reaching the surface. The saline character of the spring water creates a unique experience distinct from the sulfurous and bicarbonate springs more commonly associated with Thai thermal bathing, with the salt-enriched mineral water valued within a long thermal tradition for skin comfort and a sense of wellbeing. Thailand's geothermal regions include saline spring sites associated with the rock salt deposits of the Khorat Plateau, and this site offers visitors the distinctive experience of immersion in naturally warmed saltwater in an outdoor natural setting.

Insider tip — Saline Hot Springs on the Gulf of Thailand coast near Ko Samui offers a cooler, marine-influenced thermal experience where chloride-rich groundwater mingles with geothermal heat. The moderate 35°C temperature makes extended soaking comfortable even in Thailand's humid climate. The brackish mineral water is locally reputed for soothing aching muscles after long boat journeys between the islands.
