Ljósufjöll, Volcanic mountain system in Snæfellsnes Peninsula, Iceland
Ljósufjöll is a volcanic system in the Snæfellsnes Peninsula composed of a central volcano with multiple fissure vents scattered across the landscape. The area contains crater formations, sprawling lava fields, and numerous cinder cones that create a rugged terrain.
The volcanic system experienced a major eruption in 960, when lava flows and ash deposits affected the surrounding region. This is the only volcano in the Snæfellsnes Peninsula whose activity was recorded in written historical accounts.
The name means Mountains of Light, referring to the pale rhyolitic rocks that dominate the landscape. Local stories connect this place to ancient settlements and farming traditions that once thrived in the area.
The area is best accessed during drier weather when the lava fields are more stable and safer to traverse. Visitors should wear sturdy footwear since the volcanic terrain is uneven, and wind exposure can be significant across open sections.
Beneath one of the crater cones lies a buried farm site from ancient times, offering evidence of human settlement before the volcano's recorded eruption. This discovery provides insight into early habitation patterns in this region.
