South Sister

Standing tall at 10,358 feet as Oregon’s third-highest peak, South Sister (Charity) is a magnificent, towering objective that anchors the southern boundary of the Central Cascades. While it offers a demanding, non-technical wilderness hiking route during the high summer months, winter and spring transform the mountain into a premium arena for steep snow climbing clinics and world-class backcountry ski descents down its open volcanic faces.

Timberline Mountain Guides provides tailored, expert-led trips up South Sister for trekkers and winter alpine athletes alike.
