South Sister, Oregon (10358 ft)
Deschutes and Ochoco National Forests
Route: South Side from Devils Lake
The South Sister Climbers Trail (No. 36) starts at the Devils Lake Campground just off the Cascade Lakes Highway (5480 feet). From this campground the trailhead sign indicates it is 6 miles to the South Sister Summit. Follow the South Sister Climbers Trail north across the highway and begin climbing through the forest along Hell Creek below Devils Hill. The trail soon leaves Hell Creek and climbs into a narrow canyon. The trail climbs the head of the canyon and reaches an open ridge where one finally gets a full view of the South Sister.
Follow the trail across the broad ridge above Moraine Lake directly towards South Sister and up its southern slopes. At about 8850 feet the trail intersects another climbers trail at the terminal moraine of the Lewis Glacier. Continue following the trail up the South Ridge on red cinder to the false summit at 10200 feet. Walk across the summit crater on snow and climb the last few feet on rocky ground to the true summit on the Northeast rim of the crater (10358 feet).
