Vatnshellir Lava Cave Tour

Overview

Dig deeper into Iceland's geologic history by touring the Vatnshellir Lava Cave on the southwestern end of the Snæfellsnes Peninsula. A 2.5-hour drive from Reykjavik will get you there, to the most visited cave in the country.

The cave is an 8000-year-old lava tube created by a volcanic eruption from a nearby crater in the Purkhólar crater family. As the lava rushed down the hill in the form of a river, it began to cool on the surface, creating a crust. When the eruption stopped, all the lava from underneath the crust continued to drain, leaving behind a hollow tube.

To start the tour, you'll head down several flights of stairs to reach the lava tube itself—the eruption and receding lava left behind minerals that you can still observe today. As a result, the rocks compose vivid colors: reds from iron deposits, yellows from sulfur, and greens from copper. Enjoy walking through this 650-foot-long (200-m) tube, which reaches depths of over 100 feet (35 m).

Tips for future travelers

A few low spots but mainly extremely large inside the caves. A couple tall flights of stairs to go down (and up) into the caves.

Our tour guide was informative and provide us with a safe and pleasurable experience. He was great at answering our questions and was very knowledgeable about the geology of the area. He did not rushes through and we had plenty of time to take photographs.

I found it really interesting to compare a lava cave to a limestone cave. Our guide, Andre, did a very nice job of explaining what we were seeing. Read more

This is a good activity to do on a bad weather day since it is underground. As the information will tell you, there are no restrooms here so stop at the Visitor Center nearby.

Tips for future travelers

If you've done other similar lava cave tours, don't feel compelled to do this too. We've done lava tube tours in Iceland and Hawaii, and can say that once you've seen a couple, you've seen 'em.

When the guides share the history of how this cave was found and you see the untouched rocks that have fallen it blows your mind that you are inside a lava cave. Read more

We had the great fortune to have the tour all to ourselves. The lava cave was interesting & our guide was terrific. The cave wasn't as impressive as I thought it would be, though. I suspect there are more fascinating lava caves in Iceland. Read more
