The Lava Tunnel

Explore the magnificent lava tunnel Raufarhólshellir, one of the longest and best-known lava tubes in Iceland. It is located just 30 minutes from Reykjavík and is easily accessed year round.

A journey into Raufarhólshellir is a unique experience and a great opportunity to witness the inner workings of a volcanic eruption as one walks in the path of lava that flowed during the Leitahraun eruption, which occurred east of the Bláfjöll mountains about 5200 years ago. Every winter spectacular ice sculptures are formed inside the entrance of the cave making the experience of visiting the lava tunnel even more breathtaking.

Flowing lava is an extremely hot liquid. On average, fresh lava can be between 1,300° F and 2,200° F (700° and 1,200° C).  Thankfully, there is no flowing lava in the cave or otherwise it would not be possible to enter it.  However, you will see clearly the path that the lava once flowed, some 5.200  years ago.

Yes, that is no problem. You can attend a different departure than you booked, as long as there is availability.

Water sometimes drips from the ceiling of the cave so wearing a waterproof jacket helps.
