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.

    The coolest and most amazing experience ever! We had such an amazing time, our guides were so fun and you can tell they truly love their jobs. I’m terrified of heights and the elevator was doable for me, so don’t let that shy you a way. Would recommend this tour a million times over. Thank you for an incredible experience

    Nos deux guides étaient très sympathiques. Nous avons eu des explications très détaillées. Ils étaient très prévenants durant toute la marche jusqu'au volcan et retour. Nous avons eu des protections adéquates et l'expérience était impressionnante. Les couleurs magnifiques. Nous avons eu le temps d'explorer le volcan au fond du cratère et une excellente soupe nous a été servie au retour.

    So beautiful. The volcano has such magnificent colours. We also had a very windy wet walk up to the volcano but the guides were excellent and gave us long oilskin coats to battle away the worst of it. If you think the weather will be bad then wear boots for the walk. Inside the volcano it’s very calm.
