There are a number of routes, but there is no easy way to climb this spectacular mountain. The easier two are perhaps the south-southeast ridge or the north face; all the other routes are more difficult. The south-southeast ridge and the north face are rated TD-, the south buttress is TD, the southwest face is ED1 and the east buttress is ED1/ED2.
The east buttress on the southwest face, known also as Fowler-Watts route was climbed on the 26 May 1982 and since has defeated many competent parties. It is a serious undertaking on mixed ground, steep sections of rock (difficulty UIAA V+) with key passages at A3+ and vertical rotten ice. A variation of the Fowler-Watts route is the Sykes-Clay, climbed on 10 July 1989 and rarely repeated since.
