Located in the UNESCO designated Thingvellir National Park, less than an hours drive from the capital Reykjavík, Silfra Fissure is where the Eurasian and North American tectonic plates meet to form part of the Mid-Atlantic Ridge. The magical underwater world has three main caverns with depths ranging from 10 to 60 meters: Silfra Lagoon; Silfra Cathedral; and Silfra Hall, where the continental plates are so close they are tantalisingly within reach of your fingers.
The average depth of a dive is between 7 and 12 meters. Underwater visibility is crystal clear to distances over 100 meters, creating spectacular views of the sublime lava rock formations, luminescent algae and dazzling displays of the colour spectrum as sunlight reaching into the depths is reflected, refracted and dispersed into the darkness and distance.
The extraordinary visual clarity is due to both the constant annual temperature of between 2°C and 4°C and the purity of the water. The drinkable water takes a century to trickle down from the Langjökull glacier and filter through 50 kilometres of Thingvellir’s subterranean lava fields to reach the surreal underworld of Silfra.
