Tectonic Diving: Iceland offers one of the most unique diving experiences in the world: Silfra Fissure. Located in Thingvellir National Park, Silfra is a crack between the North American and Eurasian tectonic plates filled with glacial water filtered through lava rock for decades.

The water is incredibly cold (35-39°F) but offers unparalleled visibility exceeding 300 feet. Wearing a drysuit, you will float through breathtaking shades of blue and green rock formations in some of the purest water on Earth.
