Seize the opportunity to explore the fascinating subterranean landscapes of one of Iceland's lava fields on this guided caving tour. Venture into the lava tunnel known as Raufarhólshellir and discover a hidden world filled with incredible and colourful rock formations formed over the ages. This geological phenomenon gives you an unparalleled encounter and an exceptional chance to observe the intricate mechanisms of a volcanic eruption.

After collection from your selected pick up location, we'll begin heading southeast to the Blue Mountains where Raufarhólshellir lava tunnel lies. Iceland is a hotspot for volcanic activity thanks to its position on the Mid-Atlantic range, and caving gives you a unique opportunity to go inside and see its effects. Gear up with a helmet and headlamp and follow your guide into the gaping lava tube, descending below the earth's surface.

Your guide explains the phenomenon of how the cave was formed as you make your way through its rugged and colourful interior. The walls and ceiling of the cave are covered in amazing stalagmites, stalactites, and other incredible rock formations that have formed over years and years. Learn about the different lava streams that have flowed through the cave as you gaze at the distinct, colourful, and polished marks they left on tube. After you've spent ample time exploring a subterranean wonderland, return to the surface and transfer back to Reykjavik.
