Descend into another world on this fascinating tour into Raufarhólshellir lava tunnel, one of the longest and best-known caves in Iceland. Walk the path the smouldering hot lava created thousands of years ago. This tour is perfectly suited to anyone with a sense of adventure and a passion for the gems of the natural world.

You’ll be picked up in Reykjavík in the morning and driven south, in the direction of the town of Hveragerði where you’ll find the cave. Raufarhólshellir is estimated to be around 1360 metres, making it the fourth longest cave in Iceland.

Once there, you’ll be equipped with a protective helmet and a flashlight. Your professional guide will lead you down into the tunnel and to its unique rock formations. As you traverse the tunnel, your guide will tell you everything about the cave’s geology and Iceland’s volcanism.

You’ll navigate the cave’s halls in comfort on the recently constructed footbridge which will lead you to various viewing platforms. That way, you’ll be able to marvel over the unreal range of colours of the cave’s walls caused by minerals churned up in the eruption that created the cave.

If you visit the tunnel in the winter, when frost engulfs the land, you’ll find the cave decked with dazzling ice formations that hang from the ceiling and rise up from the ground. As the light hits them, they sparkle and become iridescent when the colours of the lava rocks appear from under the ice.

The cave was formed in an eruption east of the mountain range Bláfjöll some 5,000 years ago. Flowing hot lava moved beneath the surface until the stream ceased and the rock cooled. What was left was this long cave which gets up to 30 metres wide and 10 metres high. You'll spend around an hour inside the cave itself.

Don’t miss this fascinating opportunity to explore the secret world under your feet. Lace up your boots and join this family-friendly tour. Check availability by choosing a date.

We had a great guide, very informative and very friendly. Our party was 2 adults and 4 kids ages 10-20, and we all enjoyed the tour. The bus arrangement was also very accommodating. If we can ever make it back for a second trip, we want to do the “dark, climb tour”. Loved it.

April is The Best time to see this cave-- all the gorgeous colors in the rock were covered in ice, bringing the colors out more and adding a sparkle. Everything shined. I sent the best photos home to my friends teaching high school Earth science. The tour guide was quite friendly and patient, and able to answer all the questions I could think to ask. I am so glad I booked this tour!

The lava tunnel was incredible! The way the facts and history were explained by our guide was very informative but entertaining, just the right amount of humour included to help the facts stick in your memory. Everything was so beautiful to look at and the actual walking itself was no where near as challenging as I was expecting. Lots of the walk include man made pathways and you’re given chains to put on your boots to help grip the icy parts of the floor. I would definitely consider doing the extreme tour next time I return!

The lava cave was amazing. The tour guide was very informative and funny whilst keeping the group interested. She turned off the lights to allow us to see what the cave is like in the dark which was amazing. She went out of her way to keep us safe and feel welcome. I cant remember the tour guides name but i think she was from poland, so thank you to her :)

Very helpful guide, telling interesting stuff and not letting you stay in one place for too long, so you don't get cold. Plus the guide took the photos of everyone who wanted them. Also very cool moment with turning off the lights and asking everybody to stay silent for couple minutes.

This tour was breathtaking. The cave was beautiful and had a array of colours. It was a little damp with trippings so I recommend waterproof gear. The walk through the cave was at an easy pace and our tour guide was great. He was very informative and helped make the experience amazing.
