Brennisteinsfjöll

The Brennisteinsfjöll system extends across the Reykjanes Peninsula, featuring crater rows, shield volcanoes, and visible steam vents at an elevation of 621 meters.

During the Holocene period, Brennisteinsfjöll recorded 30-40 eruptions, with a significant volcanic event in 1341 that affected European climate patterns.

British miners extracted sulfur from Brennisteinsfjöll throughout the 19th century, leaving behind infrastructure remnants that mark the industrial heritage of Iceland.

Visitors reach the geothermal areas through marked hiking trails at elevations between 450 and 500 meters, where fumaroles and hydrothermal formations are visible.

The volcanic system contains the distinctive Stóra-Kóngsfell and Þríhnúkagígar craters, which reveal information about underground magmatic processes.
