What You Can Expect

Iceland Lava Tunnels and Caves Tour from Reykjavik

Caves and Craters of Iceland Tour

After pickup from your central Reykjavik hotel, travel by air-conditioned coach into Iceland’s countryside.

Admire the craggy mountains and volcanic plains, and listen as your guide explains how Iceland’s landscapes hide a subterranean network of caves and craters. These were formed when the surface lava hardened and the hot, fluid magma underneath continued to flow, eventually forming tubes and caves.

After roughly an hour on the road, arrive at a lava system of tubes and chambers. Don your coveralls, gloves and helmet with a flashlight, and after a safety briefing, follow your experienced guide into the narrow caves.

Make your way into the cave and be struck by the extraordinary variety of colors and formations of lava around you. Hear how the different lava streams are the result of different eruptions through the centuries.

Be ready to scramble over uneven terrain and crawl along some stretches, and stop to admire incredible rock formations, and stalactites and stalagmites.

There are no handrails or cave lights — just your helmet beams and your guide to lead the way — so the tour is only suitable for those who are confident walking on rough ground and maneuvering in tight spaces.

After exploring underground, return to the surface and end your tour back in Reykjavik.
