What You Can Expect

Lava Caving at Leidarendi with Transport from Reykjavik

Explore one of Iceland's top lava caves with a professional guide!

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.

This was a shorter tour. Our guide was very passionate about the lava cave and gave us lots of information. The cave was very cool and worth seeing!

Super cool activity. My kids could not believe that I actually did this with them. We crawled, we sat in absolute darkness. Loved that the group picked us up from the hotel. Made it super convenient and fun.

Loved this tour! It was slightly more challenging than the previous reviews suggest in my opinion. There was a little bit more squeezing through tight spaces and crawling than I expected. Lenas was an excellent guide and made me feel very safe. He gave us the option to not persist with the 2nd half of the cave, which involved more crawling and small spaces than the first half. It was really interesting seeing Iceland from below! However, I wouldn't recommend this one if you have back or knee problems or if you're claustrophobic or afraid of the dark! We really enjoyed it :

Our guide Jonas has made this tour interesting and informative. We did it on our last day in Reykjavik and it turned out to be a remarkable experience. The tour is suitable for everyone as long as no physical accessibility challenge. I joined this tour with my dad and we both enjoyed it very much.

Took this on my first day, as I had arrived earlier in the morning. Good way to stay awake. The entrance to the cave was not what I expected, basically we had to crawl through an opening in the snow to get down into the cave. It had that Indiana Jones feel to it, which made it that much more fun for me. The cave was very interesting and our guide provided a lot of information about the formation of the caves, how many there are in Iceland and he pointed out many very interesting features during the tour. A great time!

Fantastic tour, can't recommend it enough. Our guide Jonas was great at what he does. I do think we got pretty lucky, having a small group of fairly well matched abilities that meant we were able to make the most of it. I'm not sure how well I would have done in a larger group
