Don Tin 1 is the first in a series of geothermal hot springs in the Don Tin area of Thailand, where a cluster of mineral spring sources emerge from the earth in proximity to one another, reflecting the geothermal richness of a localized zone of underground volcanic activity. The spring produces naturally heated mineral waters that have served local communities for bathing and traditional therapeutic practices, with its numbering indicating a mapped and catalogued series of spring sources in the same geothermal field. Thailand's geothermally active regions host numerous such clustered spring fields, where multiple geothermal sources share the same underground volcanic roots and emerge at the surface in close proximity.
Insider tip — Don Tin 1 is a natural thermal pool near Krabi on the Andaman coast, where geothermal water at 40°C surfaces through limestone karst formations characteristic of southern Thailand's dramatic coastal geology. The spring is located close to sea level in a mangrove-fringed landscape, and tidal influence occasionally mixes brackish water with the thermal flow. The setting of towering limestone cliffs draped with tropical vegetation makes this one of the most visually striking natural springs in the peninsula. Time your visit to coincide with low tide when the freshwater thermal flow is strongest and unmixed with seawater.
