South Sister Climbers' Trail -- Trail #36

Deschutes National Forest - Bend/Fort Rock Ranger District

Current Conditions

ACCESS: This trail begins at Devil's Lake Trailhead, 29 miles west of Bend just off Century Drive.

DESCRIPTION: This primitive trail climbs steeply over rugged terrain and loose cinders to the summit of South Sister. Now dormant, this composite volcano last erupted about 2,000 years ago. Rapidly changing and harsh high mountain weather requires thorough preparation for this climb, even when the skies are blue at the trailhead. Early season snow climbs require an ice axe and knowledge of its use for safety. Avoid weekends, if possible on this overused trail. 

Camping at Green Lakes, 4.4 miles from trailhead, is restricted to designated campsites only, typically full by Friday evening each weekend. Campfires are not permitted within 1/4 mile of the lakes to protect the fragile ecosystem.
