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.
