Discover the wonders beneath Iceland’s surface with a guided lava cave tour at Raufarhólshellir, featuring expert guides, stunning formations, and all gear provided.
Venturing into Iceland’s underground is one of those adventures that sticks with you long after you leave. The Lava Caving Experience at Raufarhólshellir offers a rare glimpse into the volcanic forces that shaped this impressive island, all wrapped up in an accessible, small-group tour. From captivating rock formations to ice stalagmites, this adventure promises a blend of geology, adventure, and a touch of the primordial.
What we particularly love about this tour is how it combines safety and education with the thrill of exploring a lava tube. The small-group format, with a maximum of 15 guests, makes the experience intimate—perfect for first-timers or those wanting a more personalized journey. However, one thing to keep in mind is that transport to and from Reykjavík isn’t included, so planning your timing is key. This tour suits curious travelers who appreciate natural wonders, want a hands-on experience, and aren’t afraid of a quick trek into the depths of Iceland’s volcanic past.


The tour begins at the Lava Tunnel office, where your guide—likely a certified caving expert—welcomes you for a quick briefing before heading into the lava tube. The main stop is the Raufarhólshellir lava tube, a geological marvel that stretches underground, offering a glimpse of Iceland’s volcanic activity over thousands of years.
Raufarhólshellir is renowned for its otherworldly appearance. Reviewers have described the interior as a “geological paradise,” with ice stalagmites that make the scene feel almost primordial. One guest mentioned, “The ice stalagmites made it feel even more primordial,” emphasizing the surreal beauty of these natural sculptures. The tube’s textures and colors are captivating, with some passages illuminated by strategically placed lights, creating a candle-like glow that visitors find mesmerizing.
Throughout the tour, you’ll learn about the formation of the lava tunnel, volcanic eruptions, and the geology that shapes Iceland. Some guests noted their guides as particularly enthusiastic, sharing fascinating insights with humor and charm, making the experience both educational and entertaining. A reviewer highlighted, “The lady who was our guide was amazing. She made it very interesting and you could tell how much she loves her job,” reflecting the passion behind these tours.
The tour lasts about an hour, which is perfect for those wanting an engaging experience without a major time commitment. You’ll get to walk, sometimes on crampons during winter, through the tunnels, navigating narrow spaces and skylights that flood the cave with natural light. The experience is designed to be suitable even for first-timers, with all safety equipment provided—so no need to worry if you’re not a seasoned adventurer.
