Hverfjall
Hverfjall is a large circular explosion crater in the Mývatn region, approximately 140 metres deep and 1,000 metres in diameter. Formed during a volcanic eruption around 2,800–2,900 years ago, it is one of the largest explosion craters of its kind in the world and a prominent landmark in the surrounding landscape.
A hiking trail leads to the crater rim, where visitors can enjoy panoramic views of Lake Mývatn, the surrounding lava fields and the diverse volcanic features that characterise the area. The crater’s striking symmetry and distinctive shape have made Hverfjall one of the best-known natural landmarks in North Iceland.
