Known as one of the most spectacular treks in the world, the traditional expedition route to K 2 (8611 m), the second highest mountain on earth, cuts through the greatest concentration of world's highest peaks. From pasture areas this adventurous trek leads up and down gorges, across rushing icy torrents, among broken rocks, over wire-rope bridges and through impressive glaciers up to Concordia, the so-called "throne room of the mountain gods", a spectacular junction of the Godwin Austin, Abruzzi and Baltoro glaciers. At Concordia the high mountain scenery is striking: the impressive Baltoro Glacier glaciated wilderness and, all around, countless high snow-capped peaks including Hidden Peak (8068 m), Gasherbrum II (8035 m), Broad Peak (8051 m) and K 2 (8611 m). From Concordia, after a trip to the K 2 base camp, the 21-day program continues over the Gondogoro pass. The 22-day program includes the K 2 and Gasherbrum base camps before turning back to Askoli.
