The Lava Tunnel Tour

Unique Lava Tunnel Tour is an adventure into Raufarhólshellir cave. Operated by The Lava Tunnel, the tour allows you to explore the Raufarhólshellir tunnel in South Iceland easily and enjoyably. It is a unique opportunity to see and experience the inner workings of a volcanic eruption.

The tunnel is in many places covered in large rocks and difficult to pass. A footbridge and several paths have been built over the roughest terrain making the standard tour accessible by most people. Impressive lighting in this part of the tunnel highlights the changing colors and clearly shows the powerful volcanic activity that formed the tunnel.

Every all year and even winter experience, spectacular ice sculptures are formed inside of the cave´s entrance, making an unforgettable experience.

Facts About the tunnel

Raufarshólshellir cave’s lava is a result of the Leitahraun eruption. The lava flowed from the east of the Bláfjöll (Blue Mountains) about 5200 years ago. Today, the tunnel’s total length is 1360 meters (4500 ft).

See below some more details:

– The main tunnel is 900 meters (3000 ft) long.
– It is up to 30 meters wide with headroom up to 10 meters high (one of the most wide-ranging lava tunnels in Iceland).
– Near the entrance, the ceiling has caved in, creating three columns of light inside the tunnel.
– At the end, the tunnel branches into three smaller tunnels where lava formations are clearly visible.

Do not forget to feel comfortable while exploring underground lava creations.
