Raufarholshellir lava tunnel

The Raufarholshellir is so well-known that it is often referred to simply as "The Lava Tunnel" Raufarholshellir, surrounded by rising mountains and craters, will steal your breath away even before you go inside. This incredible lava cave was formed around 5000 years ago and spans 4462 feet (1360 meters). Because the ceiling is up to 33 feet (10 meters) high, this is an excellent alternative for persons who are more claustrophobic. The tunnel was discovered in 1950 and quickly became famous throughout the world for its incredible beauty. During the winter, the lava walls are coated with soft moss, and the tunnel is carpeted in magnificent ice formations.

Previously, you could tour the lava tube without a guide. Unfortunately, this resulted in a large amount of trash being left inside, and practically all of the ancient stalactites being removed or destroyed by visitors. A major clean-up of the cave (and its three tunnels) was arranged in 2016, and now you must pay a guide to view the magnificent lava tube. The cave's interior is illuminated by lovely columns of light that come through the collapsed parts of the ceiling.
