Out of this world experience! This has been on my bucket list for 10 years and it exceeded all my expectations. The hike was beautiful, the ride into the volcano pretty neat and all those colours in the magma chamber took my breath away.

This was a once in a lifetime experience! The guides were very nice and informative and the descend inside the volcano was unreal.

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.
