1. Silfra Fissure Snorkeling Tour with Underwater Photos
Take part in a once-in-a-lifetime experience and snorkel at a site that National Geographic called one of the top dive sites in the world. Gear up in all the necessary snorkeling equipment provided, including neoprene hoods and gloves, a thermal undersuit, dry suit, and your own mask, snorkel, and fins. Then, swim through the pure, filtered glacial meltwater for the ultimate bucket list experience. Only a few spots are available each day, so secure your place now. Located in the UNESCO World Heritage Site of Þingvellir National Park, the Silfra Fissure lies in a valley where the tectonic plates of North America and Europe drift further apart every year.
