Snorkeling in a wetsuit 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 colors of this stunning, exotic underwater fissure.

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

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 group 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 sources in the world comes at a price, as the temperature lingers around 2 - 4 degrees Celsius (35 degrees Fahrenheit) all year round. The wetsuit covers your whole body. It won't protect you entirely from the just-above-freezing glacier water, but the wetsuit keeps you relatively warm. 

Unlike the drysuit, which allows you to float above the surface, the wetsuit enables you to dive a little under the surface to explore the beauty of Silfra a bit closer.
