The Silfra Rift in Iceland offers you the opportunity to dive between the American and Eurasian continental plates. It’s one of the only places in the world you can witness the crack between these plates (they move apart at a rate of 2 cm a year) let alone dive between them. A dive in the subzero glacial waters that fill these lava formations has its advantages by way off offering a diver visibility of over a 100 meters. Lack of fish in this clear water gives the diver a chance to witness beautiful nature formations and landscapes in the water; not something an ocean diver is used to! If you happen to get thirsty during your dive, don’t worry, you can drink the water you are diving in, it’s water in its purest form, resulting from melting glaciers around 50 km away. The dive site is a 45 minute drive from the Reykjavik area and you should put aside a whole day for this diving adventure. The tour costs approximately $290 and I had booked it through: http://www.dive.is.
