Once in a lifetime experience - This was an amazing experience (but not for the faint of heart). My son (22) and I (55F) were initially scheduled for the hike, but the weather did not cooperate. The tour operator reached out immediately to offer this opportunity. While being "moderately fit" and "not claustrophobic" were criteria to participate, they answered questions quickly and thoroughly. The guide (France) was excellent and fully informed, equipping us for this adventure. Be prepared for a technical and physical experience. Took approximately 5 hours and was an experience we will never forget.

Amazing, fun-filled caving experience in a natural Lava Tunnel with an awesome tour guide! - This Lava Tunnel Caving experience was absolutely amazing and is one of the top highlights of my holiday! The natural Lava Tunnel was untouched by man-made modifications like ramps or lights, which made the whole adventure feel more authentic and immersive. Being so close to ancient rock formations was incredible, and the different rock formations, like ionization or dried lava on the walls, were absolutely captivating. Our tour guide France was fantastic from start to finish. Her fun and energetic vibe set the tone right from the pick-up and continued throughout the entire experience, even during the drop-off. As an experienced geologist, she enriched the tour with fascinating insights about the cave's history and geology. She also did an excellent job supporting the whole group which was made up of several different ability levels, such as pointing out more challenging spots for the more experienced or athletic people, and showing easier paths for the others. If you're looking for an adventure that combines nature, geology, and a bit of a workout, this is it! Highly recommend this as a must-do for a trip to Iceland, and if you're unsure, I also tried the "famous" Lava Tunnel, and this was far better, had more opportunity for photos, got BETTER photos, and was more interactive and felt more personal with a smaller group.
