Iceland's Highest Peak & Hidden Volcano
Öræfajökull is a stratovolcano forming the highest peak in Iceland (Hvannadalshnjúkur, 2,110 m). It is covered by a ~600 km² ice cap. Iceland's tallest mountain is actually an active volcano hidden beneath the southern edge of Vatnajökull glacier. Despite its serene appearance, it's responsible for some of Iceland's deadliest eruptions.
Öræfajökull has produced Iceland's most deadly eruptions. The 1362 eruption was so catastrophic it destroyed an entire district, earning the name "Öræfi" (wasteland) that persists today.
Because the volcano is capped by thick ice, eruptions can trigger large floods. Modern monitoring shows no signs of imminent activity. However, the long repose since 1727 (nearly 300 years) means scientists continue to monitor for any changes.
Hvannadalshnjúkur summit offers the ultimate Iceland mountaineering challenge with 360° views of the entire country on clear days.
