A natural wonder - Vatnshellir Cave was formed when molten lava rushed downhill in a fiery lava river, creating a solid crust as it cooled. Once the eruption finished, the molten lava beneath the crust drained away, leaving behind an intricate hollow tube. Today, this underground marvel is accessible to those eager to explore the heart of Iceland's volcanic landscape.
Guided by Summit Adventure Guides, the sole licensed operator of Vatnshellir Cave tours, you'll embark on a 45-minute journey into this natural wonder. The tour is suitable for most adventurers, though participants must be able to walk unsupported on uneven surfaces and navigate two spiral staircases leading into the cave's depths.
