volcanic springs
Geothermally warmed pools
Volcanic springs are natural water sources heated by geothermal activity from underground magma or volcanic rock.
The water emerges warm or hot, often rich in dissolved minerals like sulfur, silica, or iron.
Many volcanic springs become tourist destinations for bathing, as the mineral content is believed to have therapeutic properties.
We soaked in the volcanic springs after hiking all day.
Hot springs in volcanic regions may also produce geysers or bubbling mud pools.
