Full description
Enjoy a hiking tour towards the dormant Thrihnukagigur Volcano. After your transfer and drop-off at the Bláfjöll mountain cabin, walk to Thrihnukagigur Volcano, a moderate hike of approximately 45-50 minutes, enjoying the breathtaking lava scenery en route. The hike is classified as moderately difficulty, with straight walks and limited elevations. But the surface is hilly and uneven. Upon arrival at the crater, descend 400 feet (120 meters) inside the volcano, and experience an extraordinary natural phenomenon. You will be informed about all safety procedures and how to behave inside the volcano, wearing a helmet and harness at all times. Each group is split into a smaller party of 4-5 people for safety and intimacy. After a slow 10-minute descent, to ensure the safety of passengers and provide ample opportunities to experience the amazing views, spend up to an hour inside the volcano (or less if you prefer). Expert guides will be with you at all times. End with a feast of traditional Icelandic meat soup or a vegetarian soup along with hot coffee, hot chocolate, tea or water.

    A visit to a magma chamber is very special. And a real once in a lifetime experience. The walk to the crater was not very difficult. Good for anyone who can walk a bit. The descent into the crater is fantastic! The crater itself is of course even more beautiful. Go do it, go see it! Then have a nice cup of lamb soup. And walk back like a different person.

    I’m so glad I did it! The price looks steep at first but it’s totally worth it! The staff are beyond amazing and truly passionate about showing the geology of the area. We were expecting a snow storm towards the end of our tour and they called in reinforcement and extra guides to ensure everyone get back from base camp safely. Highly recommend it!

    Unique guided trip inside the magma chamber of a volcano. Not like other lava tube or cave tours because of the method of decent and the rarity of this type of volcanic feature. The hiking in would be pleasant in good weather but wasn’t unbearable in high winds and light rain since it’s relatively short (2 miles) with brief uphill sections. I’m a slow steady hiker and I never felt pressured to go faster. Our safety seemed important to the friendly staff and they shared much of the history of the volcano. One of the highlights of this visit to Iceland. We had some issues calling them to book directly but using Get Your Guide was easy and fast, with only a small up charge.
