Amazing visibility and underwater landscape

Snorkeling in Iceland is an activity that everyone who has learnt to swim can enjoy.

The Silfra fissure in Thingvellir National Park is notorious for its amazing visibility and underwater landscape. Melt water from Langjökull glacier, located about 50 kilometres from Lake Thingvellir, travels for over 30 years through lava fields before flowing into Silfra River. This filtering process makes the Silfra water as clear as water can be.

Snorkelers experience a visibility of over 100 meters and can drink the water while swimming in it.

The fissure is the result of the American and Eurasian continental plates drifting apart. Divers are literally diving between the continents.

Your guide will walk with you to the platform and give you a briefing before gearing up. Since the water is cold, the snorkeling tour is conducted in dry suits. These suits will keep you dry and the thermo undergarments provided will keep you warm and comfortable.

Non-swimmers and pregnant women are not allowed on this tour.
