Walk inside Raufarhólshellir, one of Iceland’s longest lava tunnels, with round-trip Reykjavik transfer, helmets, headlamps, and live guide stories.

“This was a short tour of one hour but worth it. Our guide Stephanie was great at explaining complex subjects such as chemistry in simple and understandable terms. The reason for the 4* is the bus ride. We weren’t told when to come back to the bus for the return trip and got told that we were late. It was quite cold down in the tunnel and so dress warmly if you need to.”
