The Trango Towers 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.

In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs.
