Raufarholshellir is a lava tube outside Reykjavik, presented to visitors as The Lava Tunnel. Its standard guided tour lasts about 1 hour and can be booked with or without transport from Reykjavik.
How Raufarholshellir formed
The tunnel formed from lava produced by the Leitahraun eruption east of the Blafjoll mountains about 5,200 years ago. For wider geological background, read about the volcanoes of Iceland.
What the standard tour includes
The standard guided visit follows the developed show section. A footbridge and installed lighting provide a route through this part of the tunnel and reveal changing colours in the rock. The operator also states that its work includes protecting the cave for future generations.
Seasonal ice and tunnel colours
Ice sculptures form naturally near the entrance during winter. This is a seasonal feature rather than a year-round part of the standard tour.
Tours from Reykjavik
The site is outside Reykjavik, and bookings are available with or without transport from the city. You can compare Reykjavik tours, but a listing should not be assumed to include the cave unless it says so.
What to pack for the cave
Use the Iceland packing list when preparing for the cave visit and the rest of your day.
