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.
The trail enters the Three Sisters Wilderness Area shortly after leaving the trailhead. Wilderness Permits are required for both day-use and overnight travel in the Wilderness from Memorial Day Weekend until Oct. 31. Permits are available at the trailhead.
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.
