Leidarendi Cave: Lava Tunnel Caving from Reykjavik

1. Leidarendi Cave: Lava Tunnel Caving from Reykjavik

Go caving in Iceland's Leidarendi Cave. You should definitely go on this tour if you want to see what’s underneath all the lava in Iceland. You will will explore the hidden world of the lava fields as you're taken down to The End of the Road (I. Leiðarendi). Leiðarendi is about 900 meters long, and you will walk around 150 meters towards it. The cave lies in a circle and is pitch black without light, but you will get a helmet and headlight, so you will easily see the wonders the cave has to offer. You will see magnificent lava formations such as stalactites and drip stalagmites, and have an underground adventure. You might need to hunch and crawl a bit, but all in all the cave gives an easy access to the underworld of the Icelandic lava fields. The lava above the cave was formed more than 2,000 years ago.

Excellent communication regarding pick up and during tour. Great adventure. Well worth doing if you are fit and enjoy exploring. Fascinating to see lava trails and formation. Great guide, cheers Louis, not sure if you spell it that way.

Very special experience. The cave is a lot of fun. After the snorkel tour you will feel really well refreshed. Wetsuit is recommended, the extra bit of cold is well worth it to be able to dive into the depths.

Great guide, as a geologist he has a clue what he is talking about. The tour even took place just for the two of us. Highly recommended and more adventurous than you think.

Excellent and very interesting. Our guides knew these caves very well. I just advise against people who have back or knee problems

A great guide and nice tour. The cave is little, but you see the lava rocks and have a nice exploration adventure.
