Raufarhólshellir Lava Cave

Imagine standing where lava would once have flowed. Inside the Raufarhólshellir cave in West Iceland, you can do just that. At 30 meters (100 feet) across, it’s the widest lava cave in Iceland. Its hollow tunnel was carved out by streams of molten rock gushing at high speed.

Raufarhólshellir was formed in a volcanic eruption about 5,200 years ago. As the lava cooled, it solidified into different kinds of colorful rocks that today line the cave walls. Altogether, the lava tunnels at Raufarhólshellir are around 1,360 m (4,500 ft) long.

Lava caving in Iceland is an experience that’s hard to match elsewhere. Every winter, new and unique ice formations emerge on the cave walls and ceiling.
