Tour description

Diving in Iceland may sound like a daring idea but as soon as you dive into the pristine glacial waters of Silfra, your mind shifts away from the cold as you are immediately absorbed into exploring the vivid colours of this stunning, exotic underwater fissure.

Silfra is situated in Thingvellir National Park, where the earth drifts apart around 2 centimetres every year as the North American and Eurasian tectonic plates move in opposite directions – creating such natural wonders as is Silfra.

Clearest waters in the world
Glaciers melt and fill this deep crack with the clearest water that has been filtered for a century through volcanic lava rock before entering Silfra from the ground up. With an incredible visibility of more than 100 meters, Silfra is ranked as one of the clearest waters in the world.

However, one of the clearest water in the world comes with a price, as the temperature lingers around 2-4 degrees Celsius all year round (35 degree Fahrenheit).

Note: If someone in your group is not a certified diver it is possible for them to go snorkeling whilst you´re diving.
