Iceland’s Silfra Fissure, located within Thingvellir National Park, offers one of the most extraordinary diving experiences on the planet. This unique underwater marvel, formed by the separation of the North American and Eurasian tectonic plates, provides divers and snorkelers with crystal-clear glacial waters, dramatic rock formations, and the chance to explore a geological wonder.
Whether you are an experienced diver or a beginner seeking an unforgettable adventure, diving at Silfra promises unmatched beauty and a rare glimpse into a rift where two continents drift apart.
Silfra Fissure owes its existence to the tectonic movements of the Mid-Atlantic Ridge. As the North American and Eurasian plates slowly drift apart, cracks and fissures form in the Earth’s crust. Silfra is one of the few places where these tectonic movements are visible above and below water.
What truly sets Silfra apart is its water. Melted ice from the nearby Langjökull Glacier travels underground for 30-50 years through porous lava fields before emerging in Silfra. This natural filtration results in visibility of over 100 meters, making it one of the clearest diving sites in the world.
Diving at Silfra is more than just a water activity; it’s an otherworldly experience. From the moment you descend into the fissure, you are transported into an aquatic landscape unlike any other.
