The Silfra fissure is situated in the Thingvellir National Park, at the rim of the Thingvellir Lake. The area is about 45 minutes from Rejkjavík city.

The Silfra fissure is at the point where the Eurasian and the North American tectonic plates meet.  Every year, these plates drift about 2 cm further apart. This moving causes tension between the plates. This tension is released through an earthquake approx every 10 years when smaller and bigger cracks and fissures are formed. The Silfra is one of largest fissure.


If you go for a Silfra fissure snorkeling tour, you will swim in thousand years old melted glacier water. This water comes from the Langjökull glacier and it takes about 30 years to come through the underground lava into the Silfra fissure. The lava works as a natural filtering system, that is the reason why the water is so clear here. The visibility is around 60-85 m (200-280 ft) in the summer, but can be 80-100 m (260-330 ft) in the winter, absolutely world class visibility!

While your Silfra fissure snorkeling tour you will explore the four parts of the area :

  • The Big Crack – this is the narrowest part of the aera, here the tectonic plates are the most closest to each other, you can almost touch them
  • Silfra Hall – the colours and the clarity the most intensive here
  • Silfra Cathedral – you will feel yourself here like flying in a mystic cathedral, watching caves, huge rocks and the divers below you in the 23 m (75 ft) deep water

While you snorkel in Silfra, you can enjoy the beautiful nature above the water and underwater as well. Sometimes raise your head out of the water, and monitor the untouched environment around you.

I read many feedbacks about Silfra, and everybody says this is really a unique snorkeling experience. Many visitors confirm, that the photos simply can not give back the million shades of blue, you just need to see them with your own eyes. It is absolutely normal here than it is snowing while you are snorkeling, is it not funny?!
