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 North American and Eurasian tectonic plates, experiencing unmatched visibility and the rare sensation of floating directly in the divide of continents.
Snorkeling
Snorkeling is the most accessible way to experience Silfra Fissure. Participants wear insulated drysuits that allow them to float along the fissure’s surface in comfort despite the 2–4 °C water.
Even without diving experience, snorkelers are able to glimpse Silfra’s otherworldly geology, making it one of the rare adventure activities open to almost anyone.
Diving
Diving tours are available for certified drysuit divers, with guided dives averaging 30 to 40 minutes depending on conditions.
The dive is considered challenging not because of depth, but because of the cold water and drysuit requirements. Still, it remains one of the most celebrated dive sites on Earth.
Thingvellir National Park
Silfra is located in Thingvellir National Park, a UNESCO World Heritage Site and one of Iceland’s most important cultural and geological areas. Beyond snorkeling and diving, visitors can explore lava fields, rift valleys, and historic sites tied to the world’s first parliament.
