Lava tunnel caving
Reykjanes Pensinula, Iceland
Witness the inner workings of a volcanic eruption; walking in the path of 5,000 year-old lava, for a truly unique experience.
The magnificent inner tunnels of Raufarhólshellir form one of the longest lava caves in Iceland. Descend underground into the cave with your expert guide, discovering how powerful volcanic activity carved the tunnel and keeping an eye out for the spectacular ice sculptures which form during winter months.
Equipped with head torches, you'll walk through the core of this fascinating underground world, lined with colourful rock formations and lava falls, passing through spectacular columns of light where part of the ceiling once caved in.
