The Silfra fissure in the National Park Thingvellir is famous for its amazing visibility and underwater landscape. About 50 kilometers from the lake Thingvellir lies Iceland's second largest glacier Langjökull. The melting water from the glacier travels for over 30 years through lava fields before it flows into Silfra. This filtering process makes the Silfra water as clear as water can be. Divers experience a visibility of over 100 meters and can drink the water on their dives.

The Silfra Fissure

The Silfra crack has been created by the tectonical drift of the American and Eurasien continental plates. Divers are literally diving between the continents.
