Iceland – Dive Between Two Tectonic Plates
Known For Silfra rift valley, where you can dive between two tectonic plates
Overview of diving in Iceland
Diving in Iceland is not for the faint hearted, with freezing cold water greeting those that venture beneath the surface. However those divers will be rewarded with one of the most unique diving experiences in the world. The Silfra Fissure is a spectacular dive, with crystal clear water resulting in 100m visibility.
The capital of Iceland Reykjavik has a range of dive centers that offer diving, freediving and snorkeling trips to the Silfra Fissure. Prior dry suit experience and certification is needed to scuba dive in the Silfra Fissure. Snorkelers are able to use a dry suit without prior experience. We decided to use 7mm wetsuits with gloves and boots, as we wanted to try explore a bit deeper in the fissure by freediving. It was an extremely cold experience in the 2° C water however gave going deeper gives an perspective which snorkelers miss out on.
The Silfra Fissure is located in the Thingvellir National Park and is the only place in the world where you can snorkel and dive between two continental plates. The fissure is located between the North American and European continental plates, which are drifting apart at around 2cm a year.
Water in the fissure is crystal clear, with visibility reaching over 100m. A chilly 2°C to 4°C in temperature, the water is filtered through porous volcanic rock over 30 to 100 years, which never freezers due to continually flowing into the fissure.
The dive starts with a short walk from the car park to the access steps into the fissure. As you enter the water, the depth varies between 30m to 2m. The clarity and colours is certainly spectacular! At the end of the fissure is a shallow lagoon with a luminous green tinge to it, great for some interesting photos.
