Absolutely, inside of view is amazing and really unique!! But also, guides are so kind and friendly, and they make your time more special!!!

Afsana – United Kingdom

It was fantastic! weather was horrific, it was a snowstorm but the guide was supportive and reassuring and made us feel that it’s doable. Options were given to cancel but we didn’t and boy are we glad. You can’t put money on this kind of experience! The soup was delicious and well deserved!

Highlights

  • Enjoy a scenic hike across a lava field, like the surface of the moon

  • Experience a very close encounter with a volcano

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.

Includes

  • Pickup and dropoff at selected locations in Reykjavik (if option selected)
  • All safety gear (helmets, harnesses, etc.)
  • Guides
  • Traditional Icelandic meat soup, coffee/tea and some sweets (vegetarians alternatives available)

Not suitable for

  • People with mobility impairments

Meeting point

The meeting point is at a ski cabin, located in Bláfjöll (the Blue Mountains). It takes about 30 minutes on paved road to drive there from Reykjavík. The name of the cabin is Breiðabliksskáli. Please be at the meeting point no later than 30 minutes past the set departure time. That is when the pickup bus will arrive from Reykjavík. For example, if you booked the 08:00 tour, you should be at the meeting point no later than 08:30. From your location in Reykjavík, find your way to road nr. 1, heading east to the south coast. Drive straight for about 15 minutes and then turn right on to road nr. 417 (Bláfjallavegur). From there you won’t have to take another turn until you get to the meeting point. Please do not take route 42 to route 417 via Hafnarfjörður as it’s permanently closed. Make sure you continue straight when road 417 splits. Do not turn onto the gravel track.

What to bring

Absolutely a MUST DO experience. Other than the obvious inside of the volcano (so much fun)…The hike had stunning views, the guides were informative, the Icelandic soup was phenomenal, and we even got to visit with some arctic foxes. Worth every penny.
