Had a fantastic day with France leading us up the volcano. Learned a lot, France was very engaging and knowledgeable. Would definitely recommend!
Truly was an extraordinary experience. France was an exceptional guide and was insanely knowledgeable about everything from the drive right up to the top of the hike. Would highly recommend for anyone looking to see the lava fields up close and get an expert’s insight!
Very good tour. Our tour guide was very knowledgeable and took the time to make the experience enjoyable and thoughtful. Thank you.
Incredibly knowledgeable guide who was able to look at a massive lava field and immediately pick out unique lava rocks literally millimeters wide to show the group. She was also very knowledgeable about the history, industry, and economy of Iceland and many of the features we drove past. The itinerary was great with a mix of hiking, geology lessons, scenic vistas, and lunch ON some of the newest rock on earth. She made sure to warn us of potential hazards, and even had paracetamol ready when I slipped and twisted my ankle (no serious injury). The trip itself started at the base of the lava flow from the 2021 eruption sequence. It was about 2 km to the summit of a nearby mountain overlooking the lava field and active volcanic crater, with many spots still venting steam as of August 2026. There were multiple stops for rest, geology, and pictures. I have asthma but never needed my inhaler, so it was not too strenuous. The highest point was about 200m up from the parking lot. After the hike, we drove along the coast before going north towards Reykjavik. We drove past a geothermal area and briefly stopped at an incredible overlook above a lake.
This tour was awesome! France was such a great guide - she provided so many details about what we were looking at that it made the whole experience so rich and interesting. I had no idea that lava had so many stories to tell!
They canceled our tour at 10pm the night before with no explanation, leaving us with no plan for the next day and no time to find anything else. My wife loves geology, and was so excited to have a volcano tour with a real geologist; she burst into tears when it got canceled. When I emailed them to check in, all three email addresses I tried bounced back. They have not refunded us and we are now having to dispute the charge with our credit card. DO NOT TRUST THIS COMPANY.
Fantastic and educational hike up to some beautiful lava fields and expansive views of the whole region. We also stopped at a lovely lake and the mostly abandoned town of Grindavik. A couple of turns on the hike are steep, and the way down a bit slippery but it's doable. What made the tour special was the wonderful guide who taught us the many geologic forces at play, the results of continuing lava flows and made us aware of the dangers that may exist of one strayed too far on their own. Our geologist was incredibly accommodating to all guests and was a pleasant leader for the small group. Also gave an excellent recommendation for Fish Company which I thoroughly enjoyed after a great tour.
France was the MOST amazing guide! We had a small group of 8 and she was great at assessing the hiking skills early on and knowing exactly where she could take the group. She was so knowledgable and answered every question we had. Highly recommended!
This tour was the thing I was most looking forward to on my trip to Iceland and it did not disappoint. I learned all about volcanoes. The guide was an excellent science communicator and teacher. She had visuals at the start to orientate the group, provided details as we hiked, responded thoughtfully to all our questions, and was happy to repeat information as we needed. She is obviously an expert who is passionate in sharing her knowledge. I recommend booking this tour early in your trip because the knowledge gained will provide insight into the sights you will see across Iceland. Plus, it will help keep you safe on this hike and for the rest of your trip. I also recommend paring this tour with the lava show to "see" these geological forces. Dress warm, for the wind and rain. Pack a lunch. Moderate difficulty is an apt description, some elevation gain, some rough terrain but very comparable to other sites. If you are remotely interested in volcanoes, I recommend you book this tour.
Jasmine was an amazing guide. She was informative and passionate about the volcano history of Iceland and explained the area we toured in a fun and interesting manner. The trek itself was incredible. Walking through and around an area that so few get to explore was awe inspiring. I would highly recommend this tour. You haven't truly learned about Icelandic history until you have done this. No complaints whatsoever.
