Reviews Summary

Visitors consistently describe Thrihnukagigur as an amazing, once-in-a-lifetime experience, highlighting its uniqueness as the only accessible magma chamber globally. The knowledgeable and friendly staff, coupled with the stunning natural colors inside the volcano and the scenic lava field hike, contribute to an unforgettable adventure. While expensive, most agree it's worth every penny.

"An amazing, once in a lifetime experience. I mean seriously, this is the only place in the world where you can actually descend into and explore an inactive volcano that erupted around the same time the pyramids in Egypt were being built, think of how insane that is! The staff are very friendly, knowledgeable and professional, you will feel in safe hands with them. Our father is slightly disabled and uses a cane to walk, and they accommodated us and helped him experience something he will remember forever, we are very grateful for that. The tour is expensive but it is worth every penny, if you do one thing in Iceland, I would recommend this."

Gabriel Lago

"You must walk through a lava field during 45 min ... with amazing panoramic views ... and then the " diving experience " into the volcano crater starts
🐺🦊 a family of artic foxes lives there and are used to be photo taken ... childs will enjoy it."

Gabio

"Great experience. Truly a location like none other. From the refreshing hike to the lamb soup at the end the entire experience was fantastic. I've been in numerous caves but descending into the empty magma chamber was different than any other. If you enjoy moderate adventure or geology in the slightest this is a must visit."
