Flosagjá Fissure is a remarkable gorge located within Iceland's historic Þingvellir National Park, a UNESCO World Heritage site. This natural wonder, sitting at an elevation of 109 meters, is a visible manifestation of the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates are slowly pulling apart. Known for its exceptionally clear, blue glacial water, the fissure maintains a constant temperature of 3-4°C year-round, offering a unique glimpse into the Earth's geological processes.
Visitors are consistently captivated by the pristine clarity of the water at Flosagjá Fissure gorge, which allows visibility up to 25 meters deep. Many describe it as a paradise for divers and snorkelers, eager to explore the underwater landscape and impressive basalt columns. The opportunity to witness the visible separation of tectonic plates on land, combined with the stunning azure waters, makes it a truly unique and memorable destination for those exploring Iceland's natural beauty.
Before visiting, it's helpful to know that while the water is cold, specialized dry suits make snorkeling and diving possible for those interested in exploring beneath the surface. The fissure is easily accessible, benefiting from its proximity to the main trails and efficient visitor management within Þingvellir National Park. Historically, a branch of the fissure, Nikulásargjá, earned the nickname "Peningagjá" or "Money Fault" due to visitors throwing coins into its clear waters, a practice now discouraged to protect the delicate environment.
The best time to visit Flosagjá Fissure largely depends on your preferred activities. While water activities like snorkeling and diving are possible year-round due to the constant water temperature, visiting during sunset is particularly recommended for stunning photography opportunities. The area is ideal for those looking to combine geological exploration with gentle walks and breathtaking natural scenery.
Stepping into the area, you'll appreciate the sheer depth and length of the Flosagjá Fissure, which stretches approximately 730 meters and reaches depths of up to 25 meters. The historical context also adds to its allure; the gorge is named after Flosi Þórðarson, a character from the Icelandic Brennu-Njáls saga. The impressive clarity of the water, revealing the geological formations below, creates a truly immersive experience.
Whether you're interested in the unique geological features, the historical significance, or simply the serene beauty of the clear waters, Flosagjá Fissure offers a compelling experience.

Is wild swimming permitted in Flosagjá Fissure?
While the clear waters of Flosagjá Fissure are tempting, general wild swimming is not permitted. The fissure is primarily known for organized snorkeling and diving tours, particularly in the nearby Silfra fissure, which require specialized dry suits due to the extremely cold water (2-2.5°C). Unauthorized entry into the water is discouraged to protect both visitors and the delicate natural environment.
What is the historical significance of the name 'Peningagjá'?
The eastern branch of Flosagjá Fissure, known as Nikulásargjá, earned the nickname 'Peningagjá,' which translates to 'Money Fault' or 'Cracked Coin.'

How does Flosagjá Fissure compare to Silfra for snorkeling and diving?
Both Flosagjá Fissure and Silfra are part of the same tectonic rift system within Þingvellir National Park and are known for their incredibly clear glacial waters. While Flosagjá offers stunning views and is a beautiful sight, Silfra is the primary location for organized snorkeling and diving tours.

Flosagjá is more for viewing from above, though its waters are equally pristine.
