Highlights
  • Leiðarendi Lava Cave - Situated near Reykjavik, Leiðarendi stands out as a pristine lava cave that remains relatively undisturbed and is readily accessible. Its infrequent visitation compared to other lava tubes can be attributed to its internal layout. The absence of constructed walkways necessitates the use of durable hiking boots for navigation. While it offers sections where crawling is optional for those seeking an extra thrill, there are also more navigable parts that lead to the same destination, forming a sort of figure-eight pattern.

With our tours typically involving small groups, we’re able to cover the entirety of the cave’s offerings, though this may be adapted to suit the preferences of the group. Spanning a length of 900 meters, the cave showcases distinctive geological features. During the exploration, your guide will pause at various points to recount the ominous tale behind the cave’s name and to explain the geological significance of Leiðarendi and other lava caves.

What's Included
  • Caving helmet and head torch provided
  • Pick up and drop off in Reykjavik included
  • Guidance from an English-speaking driver/guide
What's Not Included
  • Food and drinks
  • Clothing suitable for the weather; waterproofs (it can be wet in the cave)
  • Boots with ankle support
Additional Information

Ever pondered what lies beneath Iceland’s lava fields? Come join us on an exploration of the secret realms beneath The End of the Road, inside Leidarendi Cave. This 900-meter long, pitch-black lava tube is a circular showcase of stalactites, stalagmites, and unexpected vibrant colors from lava formations. A lava tube is a result of volcanic eruptions, formed when the surface lava hardens, leaving flowing magma beneath. After the lava flow stops and the rocks cool, a long, empty cave takes shape – this geological marvel is referred to as a lava tube.

Less frequented than other lava tubes, the unique structural features of Leidarendi draw fewer visitors. Walking paths lack sturdy wooden platforms, hence reliable hiking boots are needed. The cave offers optional areas for crawling, for those seeking an adventure. However, easier routes can also be taken to reach the same destination, logically resembling a loose figure of 8.

  • Wear/ bring outdoor clothing, for example waterproofs as the cave can be wet inside at times
  • This is a small group tour ensuring more time is spent exploring the cave (max. 8 people)
  • Minimum recommended age is 10 years old

Fantastic driver - Voeran our transfer guide was amazing. He told us all the history about iceland and was very knowledgeable. He then linked it to the lava tunnel so we knew all the background information before thing part. The lava tunnel and tour guide in the cave was also good. Over all really enjoyed the experience. Can't wait to come back!

Very nice and unique experience. - The tour of the tunnel was longer then expected (which is good). Guide (Luis, sorry if I misspelled) was very friendly and funny, but professional, and was quite informative about the cave/tunnel. The cave, by itself, is natural, very interesting and unique. We enjoyed the tour very much.

Great tour - We did the lava tunnel tour - we had a great time, the tour guide was informative and friendly, and made sure to keep us safe at all times and ensure that everyone was comfortable. Definitely bring gloves and sturdy clothing, there's a lot of crawling and jagged edges, and you'll need proper shoes. Would really recommend for anyone comfortable with the physicality of it though.

Perfect level of adventure for my brave six year old - We explored Leiðarendi with this company. I haven’t been in a cave since I was a teenager. I’m now in my late 30s and I found the climb through this cave relatively easy. My six year old sped through the whole thing. Our tour guide, Bart, was knowledgeable and did a good job directing us. It’s helpful to have a guide for this cave, he was able to point out all the more “difficult” areas. There are a few tight spaces, but the most difficult spots are optional (unless you bring a six year old, my kid decided they were mandatory). None of the right places take more than a minute or so to get through and the pay off to trudging through them is worth it.

Exploring Below the Surface -- Caving & Snorkeling - We did a combo tour - exploring the Leidarendi Cave and snorkeling in the Silfra. Both parts of the excursion were so much fun! We were so happy that we did the combination tour --There aren't many places in the world where you can explore a lava cave and snorkel in glacier water between the tectonic plates all in one day! The cave and the river are both close to Reykjavik, which made the trip very convenient and easy. We were picked up near our hotel and dropped off in the same location. It was so nice not to have to rent a car! Our guides Julian and Natalia were extremely knowledgeable, fun and more than willing to take a million photos of us :) We highly recommend this tour and Adventure Vikings!!!

Caving & Snorkeling - We took a group of 20 to do the caving & Snorkeling tour and it was INCREDIBLE. The caving was for all levels and really exciting! It was pretty undersold on how spectacular it was going to be. The Snorkeling was a once in a lifetime experience that I will never forget. Our group of 20 left feeling stronger, extremely adventurous, happier, and closer as friends! To be immersed in Icelands beautiful nature with locals all day was really cool. Our tour guides were SO fun, extremely knowledgeable, and just the nicest. It felt like we were all friends by the end of it. Highly recommend this tour and company!

Really nice experience - We did our Lavatunnel-Tour in mid January and the entrance of the cave was totally filled with snow. Nevertheless, our guide Ivan was amazing and dug a whole for us to get in. Really an adventure and the cave was also worth seeing !!!

Watch your head - My hubby and I went ‘lavatubing’ in Leiðarendi. They call it a cave, but it is actually an old lave tunnel. We booked this trip trough tours.is. The guide we were with provided us with helmets and lights. If you wanted he had gloves (which you deffo need) and extra clothing. Due to the temperature and lack of wind it feels not all too cold and soon you’ll be working up a sweat. The ceiling of the tunnel gets very low on some points, with the lowest being just around 80cm. The tour consist really of 2 parts. The first part has some crawltrough areas, but it is pretty doable. The real low areas are in the 2nd half if the trip. For those who not feel up to go really crawling, there is the possibility to just do the first part. The tour itself is really interesting and the guide we had was very knowledgable. I would really recommend this tour!
