Snorkel in between two continents at one of the top diving sites in the planet! Silfra is located in Iceland’s National Park, Thingvellir, and is a fissure that was formed by the divergent tectonic drift of the Eurasian and North American plates. What makes Silfra exceptionally unique is not only its geological significance, but it is also world-renowned for its crystal clear, fresh glacial water. No diving experience or diving license is needed for this 5-hour guided experience, and all the gear that you need is provided. This is a small-group tour for no more than 8 guests.
