The Karakoram, the ‘Black Gravel Mountains’, this great and splendid collection of gloomy brown and black metamorphic rocks is the most unrivaled mountain range. The K-2, of all the world’s second only to Everest, shreds the jet stream at 8611 meters, at its foot stretches another wonder of the world, Concordia, a rippling, pitted, pockmarked river of ice, where great glaciers slide and slither together before separating to go their different ways. Like a proscenium, Concordia is part of the main stage of a natural amphitheatre that has no equal. Within a radius of twenty-four kilometers, stand ten of the world’s thirty highest peaks, including K-2 (8611m), Broad Peak (8047m), Gasherbrum-I (8068m), and Gasherbrum-II (8035m).
The temperatures in the area are extreme and there is a large difference between lowest and highest temperatures during a day. The monsoons do not affect the Karakoram. The best climbing and trekking season is from May to till end of September each year. However, Climbing and trekking can be possible during winter.
