 Despite all the dangers, the Bottleneck is still technically the easiest and the fastest route to the summit.Most climbers choose to use it to minimize time required to spend above 8,000 metres (the "death zone").The standard route, the Abruzzi Spur (SE), as well as the Cesen route (SSE Ridge, which joins SE Ridge), and the American variety on the NE Ridge (traverse across E Face to SE Ridge), all attain the summit via the Bottleneck.
