Wander through Iceland's lava tunnels


Searching for an unparalleled experience in Iceland? Why not explore the island's lava tunnels? These caves, which are carved out by lava flows, are where you can explore the depths of the island and admire the natural works of art created by thermal shock.

The most famous lava cave in Iceland is the Raufarhólshellir Cave. This nearly two-mile-long tunnel was formed over 5,000 years ago and feels as if you’re following the path of a lava flow. This cave, along with the Leiðarendi Cave, is where you can spot stalactites and stalagmites, as well as polished walls, a fascinating phenomenon that will delight photographers.

Next, discover the Viðgelmir Tunnel and its dazzling array of colors. Located in the Hallmundarhraun lava field, walk along the footbridge that takes you through the stalagmites and observe the different shades of orange and violet that adorn the tunnel walls.
