Discovering Silfra Fissure Iceland

What Is the Silfra Fissure?

Silfra fissure is an underwater abyss that was made when the North American and Eurasian plates pulled apart. In Þingvellir National Park, the fissure appears because of continual volcanic activity and movement for thousands of years. Here, you can explore between two continental plates by diving or snorkeling, which is hard to do anywhere else. The depth of the fissure is up to 63 meters, yet snorkeling tends to be in the shallower places. The unusual features of Silfra’s geology make it a famous tourist site in Iceland’s volcanic country.

Why Snorkel Silfra?

Swimming through Silfra gives an amazing feeling because the water is remarkably clear and you can pass from one continent to the other. Over many years, the lava-filtered glacial water gives the ocean exceptional clarity so divers can see up to 100 meters, or more than 300 feet. Underwater snorkeling allows people to observe bright scenery with unique rock formations and clear views that look almost unreal. Because of its lovely scenery and interesting geology, lots of people from different countries visit Iceland to observe how its land changes and is shaped by the forces below.

When to Snorkel Silfra

You should try snorkeling in Silfra between May and September since the weather is more comfortable at this time. Even if it’s summer weather, the water temperature is always lower than 5 degrees Celsius; hence, it’s necessary to be well prepared with suitable gear. During the summer, there are more hours of daylight and slightly warmer air, which makes things more enjoyable. Going on an early tour means you’ll encounter fewer people, and the water will be calmer too. The dive site at Silfra is open the whole year round, while snorkeling is only available in warm-weather seasons.
