Ever thought of swimming in extremely clear glacial water, in some of the most unique diving and snorkelling sites in the world? If so, Iceland will be your heaven. If not… well, you should!

Within the past decade, Iceland has become known for its diving and snorkelling sites. The “out of this world” water clarity together with the extraordinary underwater landscapes make Iceland a top destination for adventurous divers and snorkellers, wishing to experience the chill of a cold-water experience. So, here is a written a complete guide for you to dive in.

Silfra fissure

Many divers worldwide have heard about the dive between the continents, the famous Silfra fissure. Silfra has become one of the top 5 dive and snorkelling site in the entire world, and for good reason!

Silfra is a fissure made by the motion of the two tectonic plates that are ripping Iceland apart – the North American and the Eurasian continental plates, which are in constant movement. The fresh water that flows through Silfra is melted glacial water coming from Langjökull glacier. It has been filtered through decades before surfacing into Silfra. It is not enough to say that the water is clear… you will hardly find any clearer water on earth. The underwater visibility is over 100 meters (330 feet), which makes the quality of your mask the only limiting point of how far you will be able to see. The underwater canyon-like landscape of the site is astonishing – you will feel like you are flying.

Silfra is in Þingvellir National Park, about a 50-minute drive from Reykjavík. Þingvellir provides a picturesque surrounding area with a waterfall, a lake and mountains in the backgrounds. We at What’s On can arrange transportation to Silfra, include this activity as part of a bigger tour or combo, or, you can add this activity to your day exploring the Golden Circle.

How cold is the water in Silfra?

The melted glacial water flowing through Silfra does not really warm up from the time it melts at the glacier. The water temperature hardly gets over 2°C (36°F) all year around, which makes it a very cold diving site.

But do not be afraid of the cold. The equipment provided on site will keep you dry and warm. A warm undergarment underneath the dry suit, together with a thick hood and gloves will make you look like an astronaut and believe me, you will not feel the cold very much. If you do, the speechless views are totally worth the cold. It is a memory you, your family, and friends will never forget.
