Hellnar: Vatnshellir Cave Tour

Nestled beside the majestic Snæfellsjökull stratovolcano lies Vatnshellir Cave, an 8,000-year-old lava tube shaped by a volcanic eruption from the Purkhólar crater family. Just 500 meters from the Purkhólar craters, this unique geological wonder offers an extraordinary glimpse into Iceland’s volcanic past.

Snæfellsjökull gained worldwide fame as the gateway to the subterranean world in Jules Verne’s A Journey to the Centre of the Earth. While the explorers in Verne’s novel descended through the glacier's summit, your adventure begins at Vatnshellir Cave—offering a chance to retrace the fictional footsteps of this legendary journey. Step into the dark depths of this ancient lava tube and uncover the story carved into its walls by nature’s most powerful forces.

What to Expect on Your Tour

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.
