Kverkfjöll Ice Caves
Kverkfjöll
Kverkfjöll is a remote volcanic massif on the northern edge of Vatnajökull where geothermal heat has carved colourful ice caves into the Kverkjökull outlet glacier, alongside steaming vents and ice-dammed lakes. Reaching the area requires a highland F-road (F902/F910) crossing to the Sigurðarskáli mountain hut, followed by a demanding hike across glacial moraine to the ice at Kverkjökull.

Important to know
- Extreme danger
- Hidden crevasses, unstable ice at the glacier edge, documented hydrothermal explosions and floods (most recently 2013), remote F-road river crossings, and no mobile coverage make this one of the most hazardous sites in the dataset.
- Guide required
- A guide or a highly experienced highland group is strongly recommended given crevasse and hydrothermal-explosion risk; organised tours to the area are offered seasonally by highland tour operators.
- Seasonal access
- Requires a high-clearance 4x4 on demanding F-roads in summer only.
Plan the stop
- Allow
- 6 hrs
- Effort · Strenuous
- Reaching the area requires a high-clearance 4x4 on demanding F-roads in summer only, followed by an official 'krefjandi' (demanding) marked hike of about 4.1 km each way, taking 2-3 hours, from Sigurðarskáli to the Kverkjökull glacier edge.
- Approach
- 4.1 km · 2 hr 30 min. Official K2 trail from Sigurðarskáli mountain hut to the Kverkjökull glacier snout, 4.1 km one way, 2-3 hours, rated 'krefjandi' (demanding) by Vatnajökull National Park, which warns of collapse risk at the glacier edge.
Accessibility
- Wheelchair · None
- Access requires an F-road crossing and a multi-hour hike over glacial moraine and ice; there is no accessible route.
- Limited mobility · None
- The approach is a demanding, way-marked but rough highland hike of about 4 km each way over moraine and ice terrain.
- Sensory · Partial
- The highland setting is vast, exposed, and often silent, with geothermal steam and sulphur smell near the ice caves; weather can change rapidly.
- Cognitive · Limited
- Route-finding across moraine and glacier edge terrain requires hazard awareness; official signage specifically warns of collapse risk near the caves.
Why it matters
The geothermal field beneath Kverkfjöll has produced repeated hydrothermal floods (jökulhlaups), most recently in 2013, when the ice-dammed lake Gengissig drained and triggered explosions in the lake bed; signage at the glacier edge warns visitors of ongoing collapse risk around the caves.
