Walk through Iceland’s 5,200-year-old Raufarhólshellir lava tunnel with a guide, helmet, and headlamp. A practical one-hour Reykjavik outing.

“The Lava Tunnel tour was an amazing experience! The view inside the tunnel was absolutely stunning, and it was fascinating to see the different rock formations created by ancient lava flows. Our guide was very knowledgeable and made the tour both educational and enjoyable. I especially appreciated learning about the difference between a regular cave and a lava tunnel — for example, how sound behaves differently, since you don’t hear an echo in the lava tunnel. It’s those kinds of small details that made the experience so unique and memorable.”
