Snorkeling & Lava caving

Great Combination

The Silfra Snorkeling & Lava Caving Tour is a great combination tour for those who want to make the most of their time in Iceland.

On this trip you will get to snorkel through one of the world’s most fantastic snorkel and dive sites, Silfra, as well as go hiking through a lava tube that was created thousands of years ago by a river of red glowing lava.

Depending on the time of year and the weather, we will choose either the Gjábakkahellir cave in Thingvellir or the Leiðarendi cave, which is closer to Reykjavik.

Both caves are lava tubes that display the same typical features of this most common type of lava cave in Iceland.  The caves are full of utterly weird and wonderful rock formations as well as a splattering of amazing colors.

Please make sure to bring good shoes, as we will walk over very uneven ground.

Even though at some points inside the cave we will have to climb and crawl a little, this cave tour is an easy one that can be undertaken by everyone who feels comfortable in confined spaces and is fit to take a short hike.

Note that snorkelers and divers can join on the caving portion of the tour together.
