Iceland is one giant geological hotspot. It’s one of the most active volcanic regions in the world, with eruptions occurring every three to four years on average. That’s because of its situation on the Mid-Atlantic Ridge: officially the longest mountain range in the world. The ridge separates the Eurasian Plate and North American Plate in the North Atlantic, and the African Plate from the South American Plate in the South Atlantic. In the center of this ridge sits Thrihnukagigur volcano. And that’s where the adventure begins…
First the good news: Thrihnukagigur volcano (don’t try to pronounce this) is dormant. It erupted for the last time about 4.000 years ago. So no need to worry. The name of the volcano means ‘Three Peaks Crater’ and was given by Arni Stefansson who was the first one who explored this volcano.
At certain moments in the year, you can go down into one of the three craters, situated about 20 km southeast of the capital Reykjavik, within the protected area of Bláfjöll Country Park.
The beauty of the crater mostly consists in the various colours found inside and its enormous – and to some extent intimidating – size.
To put it in context, the ground space of this crater equals three full-sized basketball courts planted next to each other. And the height of the crater? Well, the Statue of Liberty would easily fit into the chamber. So believe us: it’s really huge!
With the necessary gear and equipment, you can embark on a tour that opens the door to this fascinating and mysterious underground world. Is it a difficult journey? Not really, but it’s better to be in a good shape.
The minimum you need is the willingness to do a moderate 45–50 minute hike (to get to the crater) and the guts to descend 120 meters to the bottom of the crater in an open cable lift.
The whole tour takes about 6 hours (you will be surrounded by expert guides at all times) and it is possible only between May and September. The trip costs about 230 euro. We are ready to book. Same for you?
