Álftaversgígar

Álftaversgígar is a remarkable protected natural monument in South Iceland, renowned for its extraordinary collection of pseudocraters formed during the historic Eldgjá eruption of 934 CE. Located near Mýrdalssandur, this 3,436-hectare protected area represents one of Iceland's most significant volcanic landscapes, where ancient lava flows interacted with waterlogged terrain to create hundreds of distinctive rootless cones. The site holds international geological importance as a prime example of pseudocrater formation and serves a practical modern function as a natural barrier against glacial floods from the nearby Katla volcano. Protected since 1975, Álftaversgígar offers visitors an otherworldly landscape that tells the story of one of medieval Iceland's most powerful volcanic events.
