Raufarhólshellir, Lava tube near Þorlákshöfn, Iceland.
The fourth-longest cave in Iceland extends 1,360 meters in length, with sections reaching widths between 10 and 30 meters throughout the tunnel system.
The cave formed during the Leitahraun volcanic eruption 5,200 years ago when flowing magma created a solid crust while continuing to flow beneath.
Local guides lead visitors through the tunnel while sharing knowledge about Icelandic geology and the formation processes of volcanic structures.
Tours include necessary equipment like helmets and lights, with a constructed footbridge making the cave accessible for standard one-hour explorations.
Natural skylights pierce through the 12-meter thick ceiling, allowing daylight to illuminate sections of the volcanic tunnel structure.
