Enjoy all the wonders of the spectacular Víðgelmir lava cave on this guided tour into one of Iceland’s largest and grandest caves. Take a guided stroll and admire a colourful underground world on an unforgettable trip the whole family can enjoy.

Caves can often be dark and tight, but this is not the case with Víðgelmir lava cave. After descending into the cave, you’ll walk through a narrow tunnel, which is the only tight space you’ll encounter on this cave tour. The cave then opens into a wide space with countless of icicles, amazing colour display and rock formations. In winter you can see some beautiful ice formation as well.

Leading from one great hall to the next, the access walkway is lit with fixed lights at selected locations so when the light hits the icicles they sparkle, and the colours of the walls become rainbow-like. The tour guide will at one point turn off all the lights in the cave, so you’ll be able to experience the striking contrast between the light and the darkness.

Víðgelmir cave is a short drive from Húsafell, a popular destination for travellers in western Iceland. For those travelling by bus or those who would prefer not to drive themselves, pickup for this tour is available from Hótel Húsafell.  

Just shy of 1600 metres long and around 150,000 cubic metres (m³), Víðgelmir is one of the biggest caves in Iceland and one of the largest lava caves in the world. It is located in Hallmundarhraun lava field in Iceland’s highlands.

The lava field was formed over 1100 years ago, during the Viking age, when volcanic craters from under Langjökull glacier erupted. Formed by flowing lava moving under a hardened surface, Víðgelmir lava cave is one of Iceland’s hidden treasures that is well worth seeing.

Don’t miss out on exploring the stunning beauty of this magical underworld on this family-friendly trip. Check availability by choosing a date.

It was a real adventure with Emilia...going down in that huge lava cave... it was a nice expérience to live total darkness The kids and ourselves learned a lot about Icelandic volcanoes... I recommend this tour..

Beautiful drive, amazing landscape, wonderful tour! Like no other place on earth!

Just the surrounding nature of the cave is worth checking out, The cave was incredible and I would say a must do for anyone near the area. The guide was informative and entertaining! I highly recommend it!

Guide was knowledgeable and funny. Interesting drive to the cave and fun experience actually in the cave. Nice and easy your!

A great cave and a great tour! The guide is very informative and professional. What really surprised us is the experience called "Nothing to see in the cave" when all the headlights were turned off. Completely dark only can hear the drip of the water. Definitely will try the Cave Master next time!

Following a professional guide is a must. Makes it so much more fun and informative. The guide was very funny and engaging. I consider myself a big Iceland nerd and it's a pleasant surprise to be able to learn so much more about the volcano systems and lava formations in Iceland. The highlight of the trip for me was the darkness time. When everyone turned off their headlights, it was pitch black, a total luxury in this modern time. Also liked the short walk from the hut to the cave. A lot of moss and wild flowers. For this amount, it's definitely a worthwhile activity.

This tour really surprised me. The cave is really impressive and the guiding is very well managed.

This tour was really cool ! The guide knew everything, very impressive. There is no need to be scared of the tight space, Víðgelmir is very spacious. We turned off our head lights in one point and it was so amazing to be in total darkness. This is a great tour for people of all ages :)

I totally recommend this tour! The scenery was stunning and our guide was really knowledgable. You don't have to worry if you are uncomfortable in small spaces. there was plenty of room to move about and explore :)

An awesome tour and I cannot wait to go back to see it is the winter season. Everybody can enjoy the cave and no need to worry about tight places since the cave is huge

What a great tour, for a great price! Really impressive cave and really informative guide - answered all of our questions. Accessible for everyone :)

A great trip! The longest lava tube on the planet is a must visit. The total darkness experience is freaky and wonderfull at the same time! Can advise this tour to everyone!
