Walker Spur Route
The North Face of the Grandes Jorasses and the Walker Spur route.


This classic route up the huge North Face of the Grandes Jorasses, finishing on the summit at Pointe Walker (4208m), is considered to be one of the finest in the Alps.

It was first climbed on the 4-6 August 1938 by R.Cassin, L.Esposito and U.Tizzoni and it is also known as the Cassin Route.

There are now many routes on the face, some of them among the hardest in the Alps, but the Walker Spur remains the most popular.

I climbed the route during my first season in the Alps in 1980. I don’t have many photos, so feel free to add more to the page.

Getting There

The route is in France in the Mont Blanc Massif. It is approached from Chamonix, a bustling resort about 1 hr 15 min by road from Geneva airport.

A rack railway goes from Chamonix to Montenvers (1909m). From here it is 2 hr 30 min-3 hr walk up the Mer de Glace and Leschaux Glaciers to the Leschaux Hut (2431m). The foot of the spur is reached in 2 hr 30 min from the hut. 

The Route

The route is mostly on rock with some ice and mixed. The climbing is free on open faces and cracks with pitches up to UIAA VI (5.9).

Although nowhere very difficult, this is a serious route due its length (1200m) and the difficulty of retreat in bad weather. It should only be attempted by a fit and acclimatised party in good conditions.

A fast party can complete the route in a day with a bivouac on the descent (usually down the south-west side into Italy). Most parties will bivouac once on the climb.

The route is sometimes climbed in rock shoes, but an axe and crampons are needed. Take two 50m half ropes. A rack of a set of nuts, a set of cams up to Camalot 2, ten quick draws and some slings should suffice. There will probably be quite a few pegs in place. 

Route descriptions are available in guidebooks such as the Alpine Club’s Mont Blanc Massif Volume 1. Topos are available on the internet.
