Only about 30 minutes drive from Reykjavik you’ll find Raufarhólshellir lava tube. The cave glimmers with spectacular colors and is beautifully lit with minimal lighting which in 2018 delivered the designers the prestigious Darc Awards. We were mesmerised by this natural phenomenon and even the most experienced cave explorers should not be disappointed.

About the Cave

The tunnel formed roughly 5600 years ago and is the fourth longest one in Iceland at just over 1,3 km / 4400 ft long.

In 2016 the cave was closed for public in an attempt to preserve its unique lava formations. Since then the cave has been cleaned up and reopened with paths and lighting, making it an exciting journey for the whole family with your local guide and expert in geology.

Fun fact: Lava tubes such as this one, form during volcanic eruptions when the top layer of the lava flow hardens, allowing the 1000 °C hot magma to flow under it like a glowing river. As the eruption stops and the magma drains out an underground pathway is formed.

Experience the Tour

Meet us on location or choose for a pick up from Reykjavik for an additional price. Upon arrival you’ll gear up in a helmet and a headlight before you head towards the cave, just a minute walk from the parking. This is our most popular caving tour and takes about an hour to explore the tunnel.
