natural hot springs
Earth-heated water sources
Natural hot springs are bodies of water heated by geothermal activity, where groundwater rises through rock warmed by the earth's interior.
They occur worldwide, often in volcanic regions, and have long been associated with relaxation and healing: We soaked in the natural hot springs after our hike.
Many have been developed into spa destinations.
