No, this is the meet-on-location version of this tour. If you are interested in going on the tour but don’t have a rental car, please check out Raufarhólshellir Lava Tunnel Tour with a pickup option.

The Lava Tunnel is located less than 30 minutes outside of Reykjavík and is easily accessible year round. From Reykjavík, drive east on road number 01 for 18 km. Then turn right onto road number 39 (Þorlákshöfn) and drive for another 12 km. The parking lot is right by the road.

The GPS coordinates are N63° 56.407 / W21° 23.742

Lava tubes are a natural conduit, formed when an active low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream.

The total length of the tunnel is an impressive 1,360 m (4,500 ft), the main tunnel being 900 m (3,000 ft) long. The tunnel is up to 30 m wide with headroom up to 10 m high, making it one of the most expansive lava runnels in Iceland. Near the entrance of the tunnel, the ceiling has caved in creating three beautiful columns of light inside the tunnel. At the end of Raufarholshellir, the tunnel branches into three smaller tunnels where magnificent lava falls and formations are clearly visible.

No, there is no flowing lava in the cave. However, you will clearly see the path that the lava flowed during the Leitahraun eruption some 5,200 years ago.
