Experience an extraordinary underwater journey by snorkelling between two tectonic plates at the Silfra Fissure. Located in the heart of Thingvellir National Park, a UNESCO World Heritage Site, Silfra is frequently ranked among the top dive and snorkel sites in the world. The glacial water is remarkably pure, having filtered through underground lava fields for decades to reach a level of clarity that allows for up to 150 metres of underwater visibility.

The adventure begins with a scenic drive from Reykjavik into the dramatic landscapes of the national park, or select meet on location to meet the team directly at Thingvellir. Upon arrival, professional guides provide all necessary equipment, including high-quality dry suits designed to keep you buoyant and protect against the chilly glacial temperatures. You will spend approximately 45 minutes floating through the ethereal blue waters of the fissure, witnessing the literal gap where the North American and Eurasian continental plates drift apart by two centimetres every year.

While the near-freezing water is too cold for most marine life, the vibrant shades of blue and the jagged underwater rock formations create a surreal, cathedral-like atmosphere. The gentle current makes the experience effortless, allowing you to drift peacefully through the four main sections of the fissure: the Big Crack, Silfra Hall, the Cathedral, and the stunning Silfra Lagoon.

After exiting the water, the group gathers to warm up with hot chocolate and cookies, providing a perfect moment to share stories from the swim. Leave with memories of one of the clearest and most unique aquatic environments on the planet.
