Torfajökull

Torfajökull, Iceland's largest volcanic high-temperature geothermal area by surface extent, is a rhyolite caldera system in the southern highlands where intense geothermal activity produces Iceland's most extensive field of hot springs, steam vents, and coloured mineral soils in a landscape accessible only in summer via the highland F-roads. The Torfajökull system's geothermal energy feeds the warm rivers and hot spring pools of the Fjallabak Nature Reserve, including the famous Landmannalaugar, where hikers soak after crossing the multicoloured rhyolite mountains. The caldera's 18 km² extent of geothermal activity, combined with Iceland's most diverse rhyolite geology producing hills in shades of pink, yellow, green, and purple, makes Torfajökull Iceland's most visually and geologically spectacular geothermal region and the centrepiece of the country's most celebrated highland hiking landscape.
