“Must See in Iceland”

— The tunnel


The magnificent Raufarhólshellir lava tunnel is one of the most well-known and longest lava tubes in Iceland. It is at a travelling distance of 30 minutes from Reykjavik and easily accessible all year round.

A tour of the Raufarhólshellir is an unforgettable journey because of the unique experience and opportunity it presents to the visitor. It gives us the chance to witness a volcanic eruption up close while walking through the path made of lava that flowed from the Leitahraun eruption 5200 years ago, east of the Bláfjöll mountains. Spectacular ice sculptures form at the entrance of the cave every winter, making the Lava Tunnel a popular tourist attraction.

— The Tours

There are two kinds of tours given at The Lava Tunnel. Visitors can choose from the Standard tour which takes you to the most easily accessible part of the tunnel and ventures on an hour-long journey or the Extreme tour which is for adventurists and avid hikers who want to fully explore the bottom of the cave. The Extreme tour is 3 hours of walking inside the tunnel with an hour each for pick-up and drop-off. The tour organizers offer free pick and drop services to all Extreme tour takers in the Reykjavik area.

— Standard Tour


Standard tours allow visitors to explore the Lava Tunnel at a leisurely pace, enjoying the sights while they walk. There is impressive lighting and a footbridge to help tourists witness the changing colors of the lava and take in the full impact of the volcanic activity which formed the path.

The extreme tour as the name suggests is for adventure seekers as it takes visitors to the very end of the tunnel where they can see the lava falling and visit the natural monuments. The extreme tour is an unforgettable experience for nature lovers and outdoorsy people. Including pick and drop, the tour costs 19,900 Icelandic krónur.

The length encompasses an impressive length of 1360 meters, with the main tunnel going on for 900 meters. The path is almost 30 meters wide and has a height of 10 meters which is why it is the most extensive lava tunnel in all of Iceland. The caved in ceiling at the entrance has created three breathtaking columns of light in the tinnel. At the end of the Raufarhólshellir, the tunnel divides into three pathways, each showcasing the lava formations and falling magma as clear as day.
