Silfra is a world-renowned underwater fissure located in Thingvellir National Park in Iceland. This unique dive site is celebrated for its exceptionally clear water and the opportunity to swim directly between the North American and Eurasian tectonic plates. With visibility often extending over 100 meters, Silfra offers divers and snorkelers an unparalleled experience of floating amidst captivating geological formations in some of the purest water on Earth.
The key feature that makes Silfra stand out is its crystal clear water, which comes from the Langjökull glacier. It takes decades for the water to filter through the porous lava fields, resulting in a clarity that makes underwater explorations feel almost surreal. The site is divided into four main sections: Silfra Big Crack, Silfra Hall, Silfra Cathedral, and Silfra Lagoon, each offering its unique underwater landscapes.
Located within the Golden Circle route, Silfra is easily accessible from Reykjavik. The fissure lies within a UNESCO World Heritage site, Thingvellir National Park, known for its historical significance and stunning landscapes. Nearby attractions include the Geysir geothermal area and Gullfoss waterfall.
