The mighty Langjökull, the ‘Long Glacier’, is the second-largest glacier in Iceland occupying 935 square kilometers. Langjökull is about 50 kilometers long and up to 20 kilometers wide, and the ice is sometimes around 580 meters thick. The glacier reaches the highest point in its northernmost part, which is called Baldjökull, rising around 1450 meters above sea level. The local guide told us, that usually there is bad weather here and if it is sunny, then it’s very windy. But today we got a nice sunny day without any wind. We drove on top of the ice cap with a modified glacier vehicle specially made to explore the glacier environment. Then we explored the biggest man-made ice tunnel in the world, which lead us to the blue heart of the glacier.
