It is Iceland ́s largest and most spectacular - it is The Cave Víðgelmir

Hailed as the mightiest of Iceland's caves, its diversity and grandeur is unrivalled. This makes for an experience not to be forgotten. 
Just shy of 1600 meters / 5250ft, the cave features amazing colours and lava formations that lurk in the depths of the Earth.

“Great lava cave”

Having visited limestone caves but never a lava cave before, I wasn't sure what to expect. The cave was fascinating. Our tour guide was fantastic- sadly, none of us can recall her name. She had a great sense of humor without being annoying. She was also extremely knowledgeable and personable. We had a 9 and 13 year old with us and she kept their attention as well as she did the adults. Our guide gave a clear and easy to understand explanation of how lava caves are formed and how they change over time. Definitely recommend a visit if you have the time while in Iceland.

“Worth the visit”

A good spacious car park on arrival, with lovely open views, there was a new building with toilet facilities and tables and chairs to sit and you could also buy drinks there. All very clean and modern. 
The tour was excellent. The cave has recently had a board walk put down so easy to walk except for the end of the tour where you need to walk on the ground. The guide was very friendly and had good knowledge. We went on the shorter tour but after wished we went on the 4 hour trip, but we do love caves. 
Defiantly worth the visit if you want a tick on the 'to do list' for lava tunnels.

"Favorite Part of My Iceland Trip!"

Visiting The Cave was my favorite part of our trip to Iceland! It is a guided 1.5 hour tour through the largest lava tube in Iceland. Our tour guide had studied geology and was very informative and entertaining! Highly recommended for those interested in science and nature. It is amazing to be down in the cave! 

You have to travel down a gravel road over lava fields to get there. The visitor center was clean and modern - with restrooms, snacks and drinks available for purchase, friendly staff who fully explain the experience before you purchase your tickets. Their prices are on par with other tours in the area and I found it to be fully worth it! The stairs and platforms in the cave are sturdy and well-made. 

Bring gloves and warm clothes, and keep in mind it's much colder in the cave than above ground. Not appropriate for small children, disabled or anyone who has difficulty with stairs, or those with short attention spans/find science boring. 

Lastly, grab the free map at the counter before you leave! It was the best and most detailed map of the area I found- better than the ones in the multiple guidebooks I had! Bonus!

“Absolutely Brilliant. ”

My partner and I originally hadn't heard of this attraction but our tour with 'Into the Glacier' was cancelled and we decided to look around the area for something to do. We were very lucky to find this - it truly made our day. We had an amazing tour guide - Emilia, who really made the experience. 
For the equivalent of £40 pp the walk takes you down the largest lava tube in Iceland - and the rock formations in the tunnel are amazing. Emilia knows her stuff and made brilliant jokes the whole way - we had helmets and lights on which gave it a very adventure-y feel without being too dangerous. It was very cold in the tunnel but luckily we had been prepared for that! 
My highlight from the trip was definitely when we were 700m into the tunnel and we all turned our headlights off! 

A captivating, knowledgeable guide and a beautiful natural phenomenon. Plus I feel I've learnt something about volcanos and lava! I would highly recommend it.

“Not to be Missed”

We had planned to see the Ice Tunnel but after things didn't go as planned our Guide took us here. We were so glad he did. ( and glad he was driving and new where to go). One of the highlights of our week in Iceland. Dress warmly as after an hour inside the cave you definitely start to feel a chill. We loved that it's just a short walk to from the small and clean and modern check in building where you get your helmet with lamp to the stairs leading down into the cave. Tours are on the hour when we were there. Our guide was as interesting as the cave itself and made the time fly by. So knowledgeable with great stories. The formations are really fascinating and the lighting and stairs and platforms are impressively well done. We enjoyed every minute!

"Awesome cave"

Awesome cave and probably the best guided tour I've ever been on! Our guide Sarah was great! As a professional geologist she shared some fascinating facts with us, was able to answer any questions and also offered quite some entertainment! Can only highly recommend this company to everyone!
Thanks for the great afternoon!

Megan - The Lure of Volcanoes

The natural world with its ever-changing wonders continues to intrigue me and further deepen my curiosity. Understanding how volcanoes, tectonic plates and orogenic* episodes have shaped our landscape in the past, and continue to do so in the present is why I pursued Geology to a higher level. MORE

I like to think of myself as an all-round kind of person, having a difficult time to focus on any one thing, but being a geologist, you might expect me having a thing for rocks. Well, I do. MORE


I really wanted to become an astronaut. I managed to learn most of the constellations and got a telescope on my 12th birthday, I still have it and use it. Seeing the sun, the moon, an eclipse through a telescope is something else. MORE

Stepping out of the norm, challenging myself to go higher and further, into the unknown. The thrill of being by myself sitting on a ledge after a successful climb, driving in snow so soft that you will sink up to your waist if you get out of the car. MORE


Geology is such a unique subject that I have learned to love the further I go with it. My main attraction to geology is the outdoor, hands-on learning you can do with. MORE


Geology has always been a great passion of mine, ever since I was little I loved to visit the cliffs along the coastline of Norfolk, collecting fossils found within the clay or large clasts of a foreign origin within the cliffs themselves. MORE


Being a Geophysicist from England often means I don´t have many opportunities to see volcanoes or experience earthquakes on a daily basis. MORE


I love being in the outdoors, and getting everyone else excited about nature is something I really enjoy. So when I was offered the opportunity to combine the two in a cave in Iceland I could not say no! More


As a young girl growing up on a farm I've always been surrounded by a lot of fresh air and nature, which ignited my passion for geology and how this fascinating world began. More


Childhood holidays hiking across the UK taught me to appreciate Earths landscapes, from rolling hills to stark cliff-edges its filled with drama and breathtaking beauty. Therefore, when I had to decide what to study at University I knew it had to be related to Earth… and thats how I discovered geology! MORE
