Hverfjall, Volcanic crater in Skútustaðahreppur, Iceland.
Hverfjall is a volcanic crater with steep walls that rises about 450 meters above the surrounding landscape and spans roughly one kilometer across. The interior drops sharply and sits among lava fields that define the black rocky terrain of the region.
The crater formed roughly 2500 years ago through explosive eruptions that were part of the Krafla fissure system. A major landslide during the initial eruption reshaped the southern rim, while lava flows from the Svörtuborgir area left their mark across the terrain.
The name Hverfjall comes from Icelandic words that describe the volcanic features of this natural formation in northern Iceland.
Two marked paths on the northwest and south sides lead to the crater rim, with the climb taking between 30 and 60 minutes. The terrain is open and exposed, so dressing for changeable weather is essential.
Visitors often overlook that the southern crater edge was reshaped by a massive slide during the eruption. This explains why that side has a different form and structure compared to the rest of the crater.
