Silfra Fissure

Silfra Fissure is one of Iceland’s most extraordinary natural wonders - a crystal-clear rift where you can snorkel between the North American and Eurasian tectonic plates.

Silfra Sissure Snorkeling, Iceland

Beneath the rugged lava fields of Iceland’s Thingvellir National Park lies a geological marvel: Silfra Fissure. This narrow chasm, filled with icy glacial water, captures the clash of continents and the purity of Iceland’s glacial landscape. It is both a breathtaking natural wonder and a living record of the restless planet beneath our feet.

Today, visitors from around the world enter Silfra’s waters to snorkel and dive between the tectonic plates, experiencing unmatched visibility and the rare sensation of floating directly in the divide of continents.
