Viðgelmir isn’t only Iceland’s largest lava cave, but also one of the largest lava caves in the world. Visitors will find themselves in an underground world of crystal lava and stunning rock formations. Enjoy Iceland’s volcanic power first-hand with a trip to Viðgelmir!
Vidgelmir is a lava tube cave. It’s located beneath Hallmundarhraun Lava Field in West Iceland. The cave was created by a massive volcanic eruption in 930 CE. The eruption lasted several years and spread lava over a 78 sq-mi (200km2) area.
Vidgelmir is the largest lava tube in Iceland, with a volume of more than 5 million cubic feet (150,000 cubic meters). It’s 1585 m. (5200 ft.), 15.8 m. (52 ft.) at its highest and 16.5 m. (54 ft.) wide.
A lava tube cave is formed when the outer layer of a lava river cools. This creates a solid shell around the molten lava. The liquid lava then flows out of the solid shell, leaving behind a tube-shaped cave. Iceland has more than 500 lava tube caves.
Vidgelmir contains many lava stalactites and stalagmites. Stalactites are formed when lava on the ceiling of the cave cools and drips towards the ground, like lava icicles. Stalagmites are formed when lava collects on the floor. Both of these lava formations are eerie and beautiful.
Vidgelmir is located in Borgarfjörður in West Iceland. The cave is about 85 miles (136km) from Reykjavik and 215 miles (345km) from Akureyri. Nearby attractions include Langjökull Glacier, Snorralaug Hot Spring, and Snaefellsnes National Park.

For centuries, Icelanders have told tales about outlaws living in caves. Vidgelmir is proof that this really happened!
In the cave, researchers discovered human artifacts from the Viking Age. Exile was a common punishment at that time, and many outlaws were forced to live out their days in hiding. The artifacts from Viðgelmir are now in the National Museum of Iceland.
