Búrfellsgjá

Búrfellsgjá is a remarkable volcanic formation near Búrfell in Southwest Iceland and a popular destination for hikers interested in the geology and lava landscapes of the area. The gorge is part of an ancient lava channel formed when molten lava flowed from Búrfell and carved a distinct route through the surrounding landscape.

Close to the crater, Búrfellsgjá is relatively narrow, approximately 20–30 metres across, with steep rock walls. Farther down on the flatter ground, the lava channel becomes wider and shallower. In its broadest sections, Búrfellsgjá and the neighbouring Selgjá reach more than 200 metres in width, while the walls of the channels are commonly around 5–10 metres high.

The landscape changes where the Hjallamisgengi fault crosses the lava field. Here, open fissures and rocky steps can be seen around Hrafnagjá, and beyond this area the lava channel continues under the name Selgjá. These geological features provide a clear example of how both volcanic activity and tectonic movement have shaped the landscape of Southwest Iceland.

Búrfellsgjá and Selgjá are also connected to Icelandic cultural history. Sheltered areas beneath the lava walls were once useful for livestock during bad weather, and old ruins and traces of former seasonal farming can still be found around Selgjá.

Today, the area is particularly popular for hiking and geological sightseeing. A walk through Búrfellsgjá can be combined with a hike towards Búrfell itself, allowing visitors to explore lava formations, fissures and the volcanic landscape at close range.

Búrfellsgjá is an excellent destination for visitors who want to experience Icelandic geology on foot and see how lava flows, faults and centuries of human use have shaped the landscape.
