Geology and Features of Blahylur (Hnausapollur) Lake

In 871, catastrophic-level volcanic activity from the Torfajokull and Bardarbunga stratovolcanos had far-reaching effects across the Icelandic Highlands, including the formation of Blahylur.

Blahylur is a maar, a type of volcanic crater that forms when groundwater contacts hot lava. Typically, a maar fills with water to create a shallow crater lake, as it did with Blahylur.

Blahylur got its name from the deep blue color of its water. The striking contrast of the blue water against darker browns, greens and greys forms a landscape of incredible beauty.

The lake covers an area of around 30 hectares (74 acres), sitting at 1870 feet (570 meters) above sea level. Blahylur is home to small brown trout that some people choose to climb into the crater to fish. 

It’s easy enough for visitors to walk down to the lake to appreciate a close-up view of the water. A short walk to the crater’s highest point offers unbeatable views down to the lake and across the surrounding terrain.
