Silfra fissure exists due to the North American and Eurasian tectonic plates separating around 2 centimeters a year - leaving a rift in the landscape between them. This rift is filled with glacial water from Langjökull glacier that has been filtered through lava fields for decades before reaching Silfra - making the water exceptionally clear and drinkable.Special effects, including wind, mist and scents, combine with the ride’s motion to create an unforgettable experience.
