Witness the inside of a volcano and walk along the path where lava flowed thousands of years ago. On this tour you will visit the lava tunnel Raufarhólshellir which is located only 30 minutes from Reykjavík. The lava tunnel is one of the biggest in Iceland and is up to 30 metres wide and 10 metres high.

The lava tube ceiling has caved in near the entrance, which creates beautiful columns of light. You will experience an amazing range of colors in the tunnel which is caused by the different mineral types of the rock. The lava tunnel is a unique nature experience and is like entering into a new world. You walk around 350 metres into the lava tunnel and the temperature in the cave is around 4 degrees. The cave has also been the location for scenes from the Hollywood movie Noah with Anthony Hopkins.

Guided walk through the Lava Tunnel. Fantastic and beautiful worth seeing. Walkway in place but some areas of unsteady walking across rocks and ice.

We were collected from bus stop 9 but returned to bus stop 12 and expected to walk back to our hotel in blizzard conditions. We were not forewarned of this and my husband has a bad knee, so it was a bad end to an otherwise good trip.

This excursion was fantastic and well worth and visit. Our tour guide was brilliant and her humour really made it extra special. The lava tunnels are stunning and the history about them was fascinating. Would highly recommend.

Overall the lava tunnel trip was very good and the guide was very informative the only downside was the transfers it wasn't very clear on pickup times and what bus to get then at the bus terminal no one to meet you and you had to find the next bus yourself .
