Tour Details
Silfra Snorkel Adventure
Your subaquatic adventure to the Silfra Fissure, designed for the entire family to enjoy, is set in the Thingvellir National Park, a UNESCO designated World Heritage Site. Book this Reykjavik tour now for an incredible Iceland experience at a low price.
Begin your Reykjavik tour by being comfortably transported to the continental rift separating America and Europe. The resulting tectonic activity here made the Silfra Fissure and its unique rock formations. Idyllic, blue waters fill and form this narrow channel near a giant lava field and active volcano.
First, your PADI certified diver/guide will equip you with snorkeling gear and a specialized dry suit, keeping you warm in the glacial waters. Then, you're all set to venture out, allowing the current to sway you through this otherworldly waterscape. Silfra Iceland offers a breathtaking snorkeling experience which is frequently rated as one of the world's top ten dives. Snorkeling here in the canyon between the American and Eurasian tectonic plates, which have been moving apart at the rate of 2 centimeters per year, will take you into a magical sub-aquatic world. Colorful marine algae, including the bright green kind, often called "troll hair," add jewel bright colors to this deep blue world. The water at Silfra flowed from the Langjokull Glacier, and has been purified on its journey through lava for around half a century, giving Silfra the unrivaled crystal clear visibility for which it is famous. Widely celebrated among the diving set, the crystal clear waters in the Silfra Fissure offers up to 328 feet of underwater visibility. Moreover, the total experience lends a feeling of absolute weightlessness. This really is a remarkable dive, truly a once in a lifetime dive!
As you glide through Silfra, extraordinary rock formations will be revealed to you. There are four sections, each with a different character: the deep Silfra Crack, the majestic Silfra Hall, the expansive and rich blue world of Silfra Cathedral, and Silfra Lagoon, which has the most incredible visibility.
