FAQ

What is Silfra?

Silfra is a rift formed by the separation of the North American and Eurasian tectonic plates. Unlike any other snorkeling site on Earth, Silfra is filled with crystal-clear glacial water that has been filtered through lava rock for decades, resulting in visibility that extends beyond 100 meters. The water remains a constant 2-4°C (35-39°F) year-round, making it one of the most unique underwater experiences available. The vivid colors, dramatic rock formations, and sense of floating between two continents create an unforgettable adventure.

Information about Silfra

Earth is divided with underground tectonic plates. Iceland is situated right in the middle of the two of them – North American and Eurasian Tectonic Plates. Silfra Fissure is one of the places in Iceland where you can see where the tectonic plates have slowly been separating – yet not on land, but under water.

In this magical place, the water is considered to be one of the cleanest waters in the world, with a visibility of more than 100 meters. This incredibly clean water comes from the melted ice of Langjökull glacier.

Join us on an adventure in Silfra – the only place in the world where you can snorkel in the middle of two tectonic plates.

During the activity, you will be swimming between two tectonic plates. Your guide will eventually send you all the GoPro photos after the tour.

* Silfra gets very busy in summer. That's why we recommend booking our earliest morning or late afternoon tours.
