Vatnshellir Lava Cave Tour: 45-min Guided Volcano Walk

Walk inside a volcano and see how lava shaped the cave

Vatnshellir Lava Cave is a 45-minute guided tour through an underground cave system on the slopes of a volcano that erupted 8,000 years ago. You explore different lava formations (stalactites, blisters and stalagmites), while learning about Iceland's geology and lava tubes. A live English-speaking guide leads the tour. Helmet and flashlight are provided, and children from age 5 can join.

The experience

What does it feel like to walk inside a volcano? The cave sits on the slopes of a volcano that erupted 8,000 years ago, right next to Snæfellsjökull, the stratovolcano that inspired Jules Verne's "A Journey to the Center of the Earth." You get a helmet and flashlight before you descend, and the guide walks you through different chambers, pointing out the textures and colors of the lava rock as it cooled and formed over millennia.

The tour lasts 45 minutes and covers uneven ground, including two spiral staircases you'll climb up and down inside the cave. The guide explains how lava tubes form, what you're looking at when you see lava stalactites hanging from the ceiling or lava stalagmites rising from the floor, and what the different colors and blisters tell you about how fast or slow the lava cooled. It's geology you can touch and walk through instead of read about.

The cave is suitable for all fitness levels, though you do need to be reasonably fit to handle the stairs and walk on uneven surfaces. Children from age 5 can join, so families often book this as a morning or afternoon activity on Snæfellsnes.
