Guide to Askja Caldera

The Formation of Askja Caldera

Askja Caldera, a stunning testament to the Earth's volcanic activity, was formed through a series of dramatic events. The most significant of these occurred in 1875 when a massive eruption led to the collapse of the land, creating the caldera as we see it today.

This event not only shaped the landscape but also contributed to the formation of the bright blue-green waters that fill the caldera, making it a picturesque spot unlike any other.

Location and Special Features

Located in the Vatnajökull National Park, the largest national park in Iceland, Askja offers a remote and rugged landscape. The caldera is part of the Icelandic Highlands, known for their stark beauty and challenging conditions.

What makes Askja particularly special is its water-filled crater, offering views that seem more akin to the Caribbean than the Arctic. Nearby, Lake Askja (Okjuvatn) adds to the allure, being the second-deepest lake in Iceland and a barometer for volcanic activity.
