Why Snorkel in Iceland?
Snorkeling in Iceland is unlike anywhere else in the world. You can float on crystal-clear glacial water between two tectonic plates at Silfra Fissure, with visibility reaching over 100 meters. Thanks to dry suits and guided tours, this unique experience is possible year-round and suitable for beginners.
The Unique Experience of Silfra Fissure
Þingvellir National Park is one of Iceland’s most famous and historically important sites. Located around 45 kilometers northeast of Reykjavík, it is not only visually stunning but also geologically unique.
Silfra Fissure is the park’s most famous attraction for underwater exploration. It is the only place in the world where you can snorkel directly between the North American and Eurasian tectonic plates. The fissure was formed by the slow movement of these plates pulling apart, creating dramatic cracks in Iceland’s volcanic crust.
Floating through Silfra feels surreal. You are suspended in water that cuts straight through the Earth itself, surrounded by lava formations shaped over thousands of years.
Crystal-Clear Glacial Water
Silfra is known for having some of the clearest water on the planet, with visibility often exceeding 100 meters. The water originates from Langjökull glacier and travels underground through porous lava rock for decades before reaching the fissure,
This natural filtration process removes almost all particles, resulting in incredibly pure water and exceptional visibility. Many snorkelers describe the sensation as flying rather than swimming.
Year-Round Snorkeling at Silfra
One of Silfra’s biggest advantages is that it is accessible all year. The water temperature stays consistent at around 2-4°C, regardless of season, and dry suits keep participants warm and comfortable.
- Winter offers snowy landscapes and fewer visitors
- Summer brings long daylight hour and milder conditions
No matter when you visit, the underwater experience remains equally impressive.
Preparing for Your Snorkeling Adventure
Before snorkeling in Silfra, it is important to prepare properly for cold-water conditions. While all tours provide specialized equipment, wearing warm thermal layers and understanding basic safety guidelines will help ensure a comfortable and enjoyable experience. A little preparation goes a long way in making your snorkeling adventure smooth, safe and unforgettable.
