Kverkfjöll, Mountain range and volcano in Fljótsdalshérað, Iceland.
Kverkfjöll is a volcanic mountain range at the northern edge of the Vatnajökull glacier in Fljótsdalshérað, reaching a peak of around 1,900 meters (6,200 feet). The range combines glacier-covered ridges with active geothermal zones where warm water rises through the ice from below.
The Kverkfjöll volcanic system has been active for thousands of years, shaping the surrounding glacier through repeated eruptions and heat output. The last notable eruption phase dates back roughly 1,300 years, after which surface volcanic activity dropped, though geothermal heat has continued ever since.
In Icelandic folk tradition, the area around Kverkfjöll was seen as a place of raw, unpredictable forces, and old travel routes were shaped around it. Today, visitors come from far away to stand where hot springs bubble up directly beneath a glacier.
The area is most accessible in summer, but reaching it requires a high-clearance four-wheel-drive vehicle and solid route-finding skills, as highland tracks can be rough and unmarked. Guided tours are strongly recommended since weather and ice conditions can shift quickly.
Beneath the glacier, geothermal heat has carved ice caves where hot springs run inside walls of ice, making this one of the few places on Earth where you can stand surrounded by ice while steam rises around you. Meltwater from these springs also feeds two glacier-dammed lakes, Gengissig and Galtarlón, which fill and drain with the seasons.
