Leidarendi Lava Caves

Hafnarfjordur, Iceland

The Basics

Exploring the Leiðarendi lava caves is a popular adventure day trip from Reykjavik, with its rugged terrain requiring visitors to scramble, clamber, and crawl through the narrow passageways, using flashlights to light the way. The cave itself can only be accessed with a certified tour guide, and many full-day tours combine a lava caving adventure with activities such as snorkelling at the Silfra fissure, a swim in the Reykjadalur hot springs, or a Jeep or ATV tour of the Reykjanes Peninsula.

Best in the land of Fire and Ice
Absolutely amazing experience. The lava cave was beautiful as were the mountains around it. The guide “B” was funny, helpful and full of information. The snorkeling was unbelievable. Both Luis and Alberto were fantastic guides. They were charming, funny, and very helpful/professional. You have the option of a wet or dry suit and they do a great job explaining both and getting you suited up. Once in the water, it is breathtaking and the length of time is perfect!

When to Get There

The Leiðarendi lava tubes are open year-round, but the most popular time to visit is summer. Plan an early morning tour if you want to avoid the crowds and always book ahead to avoid disappointment. Visiting in winter means you will be at the mercy of the weather, although cancellations are rare.

Discovering the Land of Fire and Ice

The Leiðarendi tube caves are one of the most accessible lava tubes in Iceland. The natural phenomenon was formed more than 2,000 years ago when hot magma flowed over already petrified lava. The network of caves run beneath the Stora-Holuhraun lava field for more than half a mile and are renowned for their spectacular lava formations, including solid lava streams, lava flakes, stalagmites, and stalactites, as well as natural ice sculptures, which form in winter.
