Explore the magnificent Lava Tunnel, or cave Raufarholshellir, one of the longest and best-known lava tubes in Iceland. It is located just 35 minutes from Reykjavik and is easily accessed year round. A journey into The Lava Tunnel 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 5.200 years ago. Get to explore the tunnel in an easy and enjoyable manner on our standard tour. The tunnel itself is a natural wonder, therefore the terrain is not easily accessible. To help our guests navigate through it, we have installed a foot bridge and lighting rigs into the rock bed. The lights illuminate the cave, further enhancing the experience and highlighting the ever-changing colors, landscape and geological formations inside the cave.
