Description
Snorkel between the North American and Eurasian tectonic plates in Silfra Fissure on this small-group tour from Reykjavik to Thingvellir National Park, with free underwater photos.
The tour starts with a drive from Reykjavik to Thingvellir National Park, a UNESCO World Heritage Site on the Golden Circle route. The park sits in a rift valley formed by the separation of two continental plates, and Silfra Fissure lies in this rift.
Silfra's water comes from Langjokull Glacier, about 37 miles (60 kilometers) to the north, and is filtered through porous lava fields for decades. This gives visibility of about 328 feet (100 meters), and Silfra has some of the clearest water on Earth.
At Silfra, you put on a fully insulated drysuit to stay warm in the glacial water. Your guide gives you a full briefing about the area, safety instructions, and how to use your equipment.
After a short walk of about 490 feet (150 meters) to the entry point, you slip into the water. A slow-moving "lazy current" carries you through the rift, an experience often called "liquid meditation."
Silfra has four main sections: Big Crack, the narrowest part, where the plates nearly touch; Silfra Hall, a wider area filled with giant rocks; Silfra Cathedral, a deep corridor with some of the clearest views; and Silfra Lagoon, a shallow, calm pool.
After about 30 to 35 minutes in the water, you get out at Silfra Lagoon and walk about 1,150 feet (350 meters) back to the parking area. Then you warm up with hot chocolate and cookies, with views of the lava fields and mountains of Thingvellir, before returning to Reykjavik.
