When in Iceland, there is no shortage of adventure and the Silfra snorkel experience is at the top of any adrenaline junkie's list. After all, where else in the world can you snorkel between two tectonic plates? Nowhere.

Located in Thingvellir National Park (Þingvellir), this natural wonder is caused by the North American and Eurasian tectonic plates moving approximately 2 centimeters further in opposite directions every year. The rift is filled with Langjökull glacier water, which is filtered through lava fields for decades, purified and then enters Silfra from the ground up. This process yields some of the clearest water in the world! In fact, the water is so pure you can actually drink it. Nothing tastes quite as refreshing as crystal clear glacial water!

With pristine visibility, a dive in the water will reveal a vivid spectrum of colors - every shade of blue and green you can imagine, along with exotic underwater fissure.

A choice between using a wetsuit and dry suit will allow you either more adventure, or more comfort. You'll also have the option to rent a GoPro to use while you snorkel, and a memory card to bring home.
