Iceland - Silfra Rift Diving (Thingvellir)

Silfra is a fissure between the North American and Eurasian tectonic plates, meaning that you dive or snorkel right where the two continents meet and drift apart about 2 cm per year. Silfra is the only place in the world where you can dive or snorkel directly in a crack between two tectonic plates. This filtered glacial water is incredibly clear, allowing for underwater visibility of over 100 meters.... means you feel almost like flying.
