The former Twin Sisters Trail, which began directly west of the summit in Tahosa Valley, has been
abandoned by the National Park Service.
To reach the newer Twin Sisters Trail, follow Highway 7 to
the Lily Lake area, between mile posts 6 and 7. Turn east at the Lily Lake Visitor Center (across
the highway from Lily Lake). Bypass the visitor center and continue on a gravel road as it turns south
and heads uphill. After about 0.4 miles, this road deadends at the trailhead. Parking is available along
the side of the road on one side only.

The trail begins on an abandoned road just uphill from the parking area, at the large trailhead sign.
This trail heads in and out of National Park lands as it winds south, then east through numerous
switchbacks to timberline. After reaching the summit area, the trail leads past a communications tower
and building to one of the high points on the main summit block, at 11,413 feet. This point was
formerly the location of a fire lookout building overlooking the Tahosa Valley to the west. The true
summit of Twin Sisters (11,428 feet) is not directly accessible by trail, but can be reached by a brief
scramble by heading east about 0.1 mile from the communications building.
