[[File:K2_Abruzzi_Spur.jpg|thumb|right|The south side of K2 with the Abruzzi Spur route]]
The standard route of ascent, used by 75% of all climbers, is the Abruzzi Spur,<ref name="him_alpine_style"/><ref name="world_mountaineering"/> located on the Pakistani side, [[#Notable2|first attempted]] by [[Prince Luigi Amedeo, Duke of the Abruzzi]] in 1909. This is the peak's southeast ridge, rising above the [[Godwin-Austen Glacier]]. The spur proper begins at an altitude of {{convert|5400|m|ft}}, where Advanced Base Camp is usually placed. The route follows an alternating series of rock ribs, snow/ice fields, and some technical [[rock climbing]] on two famous features, "[[House's Chimney]]" and the "Black Pyramid." Above the Black Pyramid, the route continues along dangerously exposed and difficult-to-navigate slopes leading to the easily visible "Shoulder" and then on to the summit.  The last major obstacle is a narrow [[couloir]] known as the "[[Bottleneck (K2)|Bottleneck]]", which places climbers dangerously close to a wall of [[serac]]s that form an ice cliff to the east of the summit. It was partly due to the collapse of one of these seracs around 2001 that no climbers reached the summit in 2002 and 2003.<ref name="aaj_2005"/>

Between 1 and 2 August 2008, 11 climbers from several expeditions died during [[2008 K2 disaster|a series of accidents]], including several icefalls in the Bottleneck.<ref name=cnn_2008_0803/><ref name=bbc_2008_0803/>
