Vatnajökull Glacier

Vatnajökull

Southeast

Vatnajökull is Europe's largest glacier by volume — roughly 3,000 cubic kilometers of ice across about 7,700 square kilometers, covering around 8% of Iceland. The ice averages 380 meters thick, reaching close to 950 meters at its deepest. Beneath it sit active volcanoes including Grímsvötn and Bárðarbunga; when geothermal heat melts ice from below, the result is a jökulhlaup, a glacial outburst flood that can reshape river valleys in hours. Iceland's highest point, Hvannadalshnjúkur at 2,110 meters, rises from the glacier's southern rim. Vatnajökull National Park, established in 2008 and a UNESCO World Heritage site, is Europe's second-largest national park. Most visitors enter via Skaftafell, about 4–5 hours from Reykjavík on the Ring Road, or at Jökulsárlón lagoon. Around 30 outlet glaciers flow from the ice cap; guided hikes run year-round, and ice caves form each winter — guided access only. The glacier has lost roughly a meter of thickness per year for several decades. Guided glacier walks from Skaftafell need no prior experience; traversing the full ice cap does.
