Vatnshellir Cave

Vatnshellir Cave

An 8,000-year-old lava tube in Snæfellsjökull National Park, explored on guided tours through dramatic underground chambers.
Vatnshellir is an 8,000-year-old lava tube descending 35 metres below the surface of the Snæfellsnes lava fields. Guided tours take visitors down spiral staircases into two cathedral-like chambers filled with stunning lava formations, vibrant mineral colors, and ancient geological history. Located within Snæfellsjökull National Park, it is one of the few lava tubes in Iceland open to the public with a professional guided experience. The cave maintains a constant temperature of around 2–4°C year-round, so warm clothing is essential. The experience offers a rare window into Iceland's volcanic underworld.
