Iceland boasts some of the cleanest air in the world, which is crucial for water purity at its inception. Water evaporating over the rainforests of South America heads in the direction of the North Pole thanks to rotation and air currents. Pure natural ice is created from falling snow, which is formed in the atmosphere from water vapour. The water that freezes in atmospheric altitudes and changes into snow, receives oxygen during this process. The high amount of dissolved oxygen becomes a natural part of water, which is not quite common for European water. Raindrops freezing into snowflakes fall on Iceland’s volcanic soil. Here water was frozen for thousands of years and gradually under the pressure of other snowflakes changing into impermeable ice, it dropped down along the wall of a massive glacier all the way to the volcanic bedrock, where it began to melt under the natural influence of the temperature of the Earth’s crust.

Glaciers naturally melt away from the lower layers, which are 30,000-90,000 years old. Ice in itself does not contain minerals. Iceland has a unique geology created by the movement of the tectonic plates and a series of volcanic eruptions. Geologically, Iceland is a very young continent, where the European and American tectonic plates meet, and all volcanic and geothermal effects that this entails. Water from naturally melting glaciers undergoes natural filtration through basalt, tufa, obsidian, rhyolite and pumice. Such composition of “filtration” plates does not exist anywhere else on Earth. These rocks give the glacial water its inherent sweet taste and predetermine high pH. Thanks to these factors, the taste of glacier water from Iceland is unmistakable.

Around 11% of the area of Iceland is made up of glaciers, of which there are 269 different kinds: glacial masses, caves, tongues, mountain glaciers, glacial waterfalls, rivers and lakes… The biggest glacier mass is Vatnajökull with an area of 8,300 km², which is equal to the area of all European glaciers together. In order of area, it is followed by: Langjokull (950 km²), Hofsjökull (923 km²), Mýrdarsjökull (600 km²) and Drangajökull (200 km²). Iceland has a history of more than 300 years of scientific observation. Whatever adventure on glaciers you choose is bound to be an unearthly and unforgettable experience.
