Description

Slesse is one of the better-known summits in the Chilliwack River Valley, and certainly one of the most prized. Alpine climbers flock to the northeast buttress (the king line) but the voie normale ascends 2200m out of Slesse Creek and follows a system of gullies and ledges to the summit. The route goes at 5.6, although the climbing portion is short-lived and the majority of the route consists of exposed 3rd and 4th class scrambling. 

In Kevin McLane's Alpine Select, he describes the voie normale as a "grand route, a classic test of mountaineering, winding its way across the mountain from the northwest to the south to meet a steep juggy wall barring the bay to the summit."

This route has a bit of everything - a bushwacky start, a sustained steep climbers trail, an involved scramble requiring solid route-finding skills, and some real climbing to reach the summit. 

**This very much qualifies as an alpine climb and deserves respect as such. Bring a good alpine rack & a minimum 40m rope for rappels

Refer to the following trip report for more detailed images & descriptions of the climb.
