The Trango Towers (Urdu: ٹرینگو ٹاورز) are a family of rock towers situated in the Gilgit-Baltistan region, in the northern part of Pakistan. The Towers have some of the world's largest cliffs and offer some of the most challenging big wall climbing opportunities. Each year, climbers from around the world embark on expeditions to the Karakoram region to climb these granite faces. The Trango Towers are situated to the north of the Baltoro Glacier and are part of the Baltoro Muztagh, which is a sub-range within the Karakoram mountain range. The highest point within the group is the summit of Great Trango Tower at 6,286 m (20,623 ft), the east face of which features the world's greatest nearly vertical drop.
