A small ravine situated beneath the iconic Thingvellir National Park, the Silfra Fissure is consistently rated as one of the best diving sites in the world. It is famous for its crystalline glacial waters, which allow divers to see more than 100 meters in each direction and the beautiful emerald plants that populate the fascinating rocks below. It is part of the Mid-Atlantic Ridge, which cuts through Iceland and marks the spot where Europe ends and America begins. This means that in the Silfra Fissure, you will literally swim between the Eurasian and North American tectonic plates. The glacial water of Silfra is so clean and pure that you can take a small drink of it before you dive down into its gorgeous blue depths.

The dive begins via a small steel ladder: when you enter you will be fully insulated in your dry suit, although it may take a second for your face to get used to the temperature. Then as we explore this majestic turquoise world, you will get a profound sense of the beauty that nature creates. The dive itself is divided into four parts: The Silfra Deep Crack, the Silfra Hall, the Silfra Cathedral and the Silfra Lagoon. The most famous of these is the lagoon, where the water stretches into the distance and divers can see more than 100 meters in each direction.

Silfra is a diving site that inspires awe and wonders in equal measure, the ideal place to have an unforgettable experience, which will whet your appetite for the sport and leave you wanting more.

Please read our Diving Handbook for more information about the tour.

The first day of the tour is all about learning, as our expert diving instructors teach you how to safely dive in a Dry Suit. In the morning we will be in the classroom, where we will learn about diving theory, how to communicate underwater and how to manage your equipment.

The morning will be spent in a local swimming pool, where you can practice being underwater and test all the new knowledge that you have gained followed by open water training dives. The open water diving take place in a lake or protected ocean site in the Reykjavik area depending on the weather conditions. We often go to Lake Kleifarvatn or Lake Thingvallavatn (Davidsgjá), all amazing places to test those new diving skills.

The guide will normally not take a camera on the first dive. Silfra can be a challenging dive, and the guide needs to have his or her hands-free in case a diver needs assistance in the water.

The maximum depth we are allowed to go to in Silfra is 18 meters. Most of the dive is spent at a shallower depth due to the topography of the site. The dive time is about 30 minutes per dive.

The water temperature is 2-4 degrees C (35-37 degrees F) all year round. The water comes from the Langjökull glacier which keeps it nice and cool, and very refreshing!

We use high-quality neoprene dry suits from Fourth Element.

Yes, you must be able to swim independently without a lifejacket, and you must be comfortable in the water.

Yes, there are 2 toilet facilities at Silfra. However, we don’t recommend that you use them for changing, as it can result in long queues.

Sometimes fish venture into Silfra from Þingvallavatn lake, but they will quickly swim back, as they don’t like chilly glacier waters. However, there is plenty of colorful seaweed, including a bright green variety known as “troll hair”, which makes the fissure unlike anything on the surface.

Before reaching Silfra, the water coming from Langjokull Glacier is filtered through porous underground lava rock for 30 – 100 years! This makes it the clearest water in the world, as lava rock is an excellent filter. It also means that the water is the clearest in the world allowing for underwater visibility of over 100 m (328 ft).
