Why snorkel in Silfra?
Silfra is famous for its exceptionally clear glacial water and its location between two tectonic plates. The water is cold all year, but guided snorkeling tours use drysuits and specialist equipment so you can experience the fissure while staying protected from the temperature.
The feeling is calm, surreal and very different from most Iceland tours. Instead of chasing waterfalls or crossing lava fields, you float quietly through clear blue water inside one of the most unique geological settings in the country. It is an excellent choice for travellers who want a once-in-Iceland experience without needing diving certification.
Planning your Silfra snorkeling tour
Silfra is located in Þingvellir National Park, around the Golden Circle route. That makes it easy to combine with other highlights in the area, especially if you are already planning to visit Þingvellir, Geysir and Gullfoss.
Tour requirements vary, so always check the individual tour page before booking. You normally need to be comfortable in the water, able to follow guide instructions and physically able to wear the provided drysuit equipment. Drysuits, masks, snorkels, fins and safety equipment are usually included, but exact inclusions can vary by operator.
