Wild Hot Springs

Iceland's Wild Thermal Heritage

Iceland's wild hot springs represent the country's geothermal heritage in its most authentic form. From century-old concrete pools built into mountainsides to natural rock basins filled with mineral-rich water, these hidden gems reward those willing to venture off the beaten path.

Seljavallalaug is one of the oldest swimming pools in Iceland, built by volunteers in 1923 and still fed by natural hot springs flowing down from the surrounding mountains.

• Pristine natural settings with no commercialization
• Temperatures from 20–80°C across different springs
• Most require hiking or 4WD vehicles to access
