Fun Facts about Raufarhólshellir

  • Raufarhólshellir is the fourth-largest lava cave in Iceland.
  • Some parts of the tunnel actually go under the road to Thorlakshofn so when you are driving there, you'll actually be driving over parts of the cave you will walk through later!
  • The cave once housed a framed epitaph document and a cinerary urn with the remains of the last member of an Indian tribe from Fire Island. Sadly, the urn was taken from the cave, and its location remains unknown.

The history of Raufarhólshellir

The history of Raufarhólshellir Cave starts with a volcanic eruption in the Bláfjöll Mountain Range about 5,200 years ago. The eruption, which is often referred to as the Leitarhraun eruption, created the scene you see today and with it an 11 km (7 mi) long crater row.

Lava tunnels are natural canals that form when active flowing magma starts to harden creating a thin lava crust on top. This lava crust then thickens as more lava flows and results in the formation of the lava tunnel roof. The hot running lava continues to flow through, but the roof stays solid.

When visiting the cave you'll be following the path of the lava, which flowed through the site a few thousand years ago.
