Vatnajokull is Europe's largest glacier. It´s size is 8300 km2 and it covers 8% of the Iceland.
It has the highest point in Iceland, Hvannadalshnúkur, which peak is 2119m over sea level.
The glacier-ice is on average 500 meters thick, but is 1000-1100 meters where thickest.
Vatnajokull is known for it's volcanic activity, so there's a true interplay between ice and fire.
Those strong forces of nature have played a key role in forming the landscape in southeast Iceland.
