Raufarholshellir Lava Tunnel

Einer der längsten Lavatunnel in Island

Raufarholshellir Lava Tunnel ist einer der längsten und bekanntesten Lavatunnel in Island. Er ist hervoragend gelegen und die Tourguides sind sehr informativ! Ein Budget freundliches Abenteuer für die ganze Familie in Island.



Raufarhólshellir is a fairytale-like lava tunnel found in the South West of Iceland, only 30 minutes driving from the capital on the road to Thorlakshofn. All around it is moss covered lava, mountains and craters and it is quietly tucked between them just waiting to be explored.

The cave is heavenly in form and color and walking through it is a memorable experience.

The lava tunnel is the fourth largest ever to be found in Iceland, measuring 1360 meters at length and 10-30 meters (33-98 ft) wide depending on where you are standing at. The ceiling is high up to 10 meters (33 ft), making the cave one of the best caves to visit if you have ever experienced claustrophobia. The average thickness of the lava ceiling is about 12 meters (39,3 ft).

Raufarholshellir  Lava Tunnel shouldn’t be visited without a guide or a lava cave expert. This small group tour is one of the most budget-friendly experiences you can have in Iceland and the guides make sure to keep you safe and informed at all times. The tour takes place only 30 minutes from Reykjavík so you can easily join the tour on a half-day mission out from the city.


  • Raufarhólshellir is the 4th largest lava cave in Iceland
  • Some part of the tunnel actually go under the road to Thorlakshofn so when you are driving there you will actually be driving over parts of the cave you will walk through later!  
  • There used to be a framed epitaph document and a cinerary urn kept at the middle of the cave but in the urn were the earthly remains of the last member of the Fire Island’s Indian tribe. This was later taken from the cave and sadly, its location remains unknown.

The history of Raufarholshellir starts like with many other attractions in Iceland, with a volcanic eruption. This special one occurred in the Bláfjöll mountain range about 5200 years ago. The eruption which is often referred to as the Leitarhraun eruption created the scene you see today and with it an 11 kilometers long crater row. Lava tunnels are natural canals which form when active low-viscosity flowing magma starts to harden creating a thin lava crust on top. This lava crust then thickens as more lava flows through which results in the formation of the lava tunnel’s roof. The hot running lava continues to flow through but the roof stays solid. When visiting the lava tunnel you will be following the path of the lava, which flowed through the site a few thousand years ago.

  • Beautivarietyrety of moss-covered lava.
  • An incredible natural array of colors which were created in the volcanic formation of the tunnel. Each color beam tells you a little bit about the history of the cave and when joining one of the standard tours to the cave you will hear all about it!
  • The tunnel was filled with stalactites but around the 1950’s, when the cave started getting more and more popular they began to disappear. Today you can only see a few of them in the cave but they are well worth the search.   
  • Incredible rock formations and naturally sculpted lava falls.
  • In winter you can see stunning icicles and ice formations all around the cave.
