Extreme Lava Tunnel Tour

All year Daily About 5-6 hours Your hotel / guesthouse in Reykjavik Challenging Min 12 years old

The Extreme Lava Tunnel Tour is only suitable for people in good physical condition. The cave was created by volcanic eruption about 5.000 years ago. It is know to Icelandic people as Raufarholshellir.

This Lava Tunnel Tour allows you to thoroughly explore this extraordinary natural phenomenon deep inside one of the biggest lava tubes in the world with an expert guide.

If you’re up for an adventure, and want a different and unique caving experience where you actually have to traverse over a difficult terrain, including big rocks and boulders, then this is the tour for you.

You will spend 3 – 4 hours in the cave, but don’t worry no caving experience is required.

Please note that we cannot guarantee that the tour will reach the end of the cave in every tour. It really depends on the fitness and overall state of the passengers/group.

Adventure awaits you!
