Departure Point


Return Details

Returns to original departure point
Depart your central Reykjavik hotel by air-conditioned minivan and travel to the volcanic Blue Mountains, home to a large lava field that covers a network of extraordinary lava tunnels and caves.

On route, listen as your guide describes how these lava tubes were formed when lava solidified above ground while magna flowed and moved beneath it, eventually forming twisted corridors and chambers.

On arrival at the plateau, put on your provided specialist caving equipment, including a helmet with a flashlight. Then, after a safety briefing, follow your guide into the Leiðarendi, one of the region’s best-known caves.

Leiðarendi translates as ‘end-of-the-journey’ in Icelandic, and the tunnel more than befits its name — a long, pitch-dark tube that opens into wide and high hallways.

With your way illuminated by your helmet torch, head through the tunnel behind your guide. Be prepared to crawl over uneven terrain along some sections as you progress.

While you explore, soak in the silent and eerie beauty around you — nature at its rawest. See the beginnings of new stalactites and stalagmites, and ogle the multicolored lava formations and streams evident in the walls and ceiling as your guide explains how the different types of lava indicate different eruptions through the ages.

After discovering the cave, emerge back into the daylight and change out of your caving gear. Then, relax on your minivan journey back to Reykjavik, where your trip ends at your hotel.

Lava Cave
, Oct 2019
I was totally disappointed with this tour. The information provided was inadequate. Unless you are under 40 I would not recommend this...uneven/unstable walking surfaces, ducking down and crawling through it, it was WET and slippery, so dark and headlamps were not suitable and guides only had two torches. There are NO services at all and you are in the middle of nowhere. Be cautious on this one. Not worth the time or cost.

The small group caving experience was interesting and exciting. I was a little surprised that 13 was considered a small group, but the two guides took care of us well.
Lava Cave to remember
, Jun 2019
The setting for this visit was just perfect plus the weather definitely helped make it a memorable experience. It is a short drive on a small bus from Reykjavik. The guides were very informative on what to expect but also how to be safe. The cave is in the proximity of some beautiful mountains and picture perfect. If you are claustrophobic this is not for you. I was there in the morning tour. Be prepare to walk and crawl through small spaces.

Amazing experience, I couldn’t recommend enough. Real caving through tiny spaces. Very small group which helps as there isn’t a lot of space under ground
Amazing experience

The small group lava caving experience was amazing! We learned the history behind the caves formation while both walking and crawling through the cave. Make sure you wear good shoes and bring gloves as the cave floor is rough! Highly recommend!
Rather ho hum, if you’ve seen many caves

VERY nice guides, but lava tube small and rather ... monochromatic. Sorry, but having seen many through US states of PA, OH, KY, TX, CO —- made this a bit boring. Too small, not much of visual interest.

The cave is a short drive away from Reykjavik. Pick up was on time and the bus had wifi. The tour was awesome! I am claustrophobic and my tour guide was very supportive and walked me through two small spaces. Otherwise, it's mostly open, you can stand in 70 of the spaces. I highly recommend visiting the cave. It's a great experience!

Our guide was Jonas. We had just gotten off the plane, and he gave us a great introduction to everything Iceland! We loved exploring the cave- it was exhilarating. Jonas shared a lot of information on the geography and culture of Iceland, which was very enjoyable. We found this to be a very unique experience-Highly recommend this!

SO MUCH FUN! Our tour guide was awesome and she really made us feel comfortable with the whole experience. It was hard to take pictures during, but so fun I really didn't mind it. If you're not a big adventurer but still want to do something exciting this is the tour for you!
