Gjabakkahellir Cave is, quite literally, a hidden geological gem here in Iceland (or at least partially, since this underground cavern was discovered in 1907). For inexplicable reasons, this cave’s name translates to “Girl Cave”, which simply adds to its mystery. This article explores everything we know about Gjavakkahellir Cave and what makes it such a must-visit place.
What is Gjabakkahellir Cave?
Gjabakkahellir Cave was discovered accidentally by workers busy constructing a road between Thingvellir and Geysir in 1907. According to researchers, the cave was created about 9000 years ago. Gjabakkahellir is not your average cave but rather what is referred to as a lava tube (more on this a little later).
It is 360 meters long and very unique due to the fact that there are openings at both ends of the tunnel, making it possible to walk straight through. It’s also one of the few caves here in Iceland you are allowed to explore on your own without booking a spot on a guided tour. Just keep in mind that tour operators usually provide visitors with all the necessary gear and equipment.
So, if you want to DIY your cave exploration, you must bring your own. This includes a flashlight and a helmet. Also, remember to wear sturdy shoes with good grip since the cave floor can be slippery, and wear enough warm clothes since it can get pretty chilly inside the cave.
Where is Gjabakkahellir Cave in Iceland?
Gjabakkahellir Cave can be found in the historic Thingvellir National Park in Iceland. Thingvellir is not even an hour’s drive from the capital city of Reykjavik, so it’s possible to explore the cave as a day outing. But since Thingvellir is one of the first stops along our popular Golden Circle route, many simply add it to their road trip trip itinerary.
How was Gjabakkahellir Lava Cave Formed?
As we already mentioned, Gjabakkahellir is not so much a cave in the traditional sense of the word but rather a lava tube. This is because of how it was formed. In typical Land of Fire and Ice fashion, there was a major volcanic eruption roughly 9000 years ago. Instead of the lava dispersing and slowly flowing across the surrounding landscape, it was a rushing river of lava.
But when you have such a dense mass of scorching hot material gushing through an icy cold environment such as Iceland, the middle remains extremely hot, while the outer parts, coming into direct contact with the cold, slowly cools down and start to harden. So, after a while, you end up with a completely hardened crush resembling a pipe with lava flowing through it.
Once all the remaining lava has flowed through, you’re left with only this hollow pipe or what we call a lava tube. While many other lava tubes in Iceland are usually discovered and entered via a hole in the ground where the roof of the tube has collapsed, Gjabakkahellir is one of the only caves that has openings on both ends, making it even more of a once-in-a-lifetime experience.
Make Gjabakkahellir Cave a Part of Your Icelandic Adventure
As you can see, Gjabakkahellir is a truly unique geological wonder that definitely deserves a visit. If you’re thinking of adding it as a stop to your road trip itinerary, we suggest renting a campervan in Iceland and making the Thingvellir Campground your first overnight stay.
This way, you can explore this captivating tunnel, immerse yourself in the island’s volcanic past, and then just relax and camp in comfort after your extraordinary outing. But however you decide to explore this geological wonder, Gjabakkahellir is not to be missed and promises to be a highlight on any Icelandic adventure.
