Parking is available on SR 666. Between FR 413 and 103 notice the old hemlocks as you approach SR 948. Parking is not safe on SR 948 - dangerous shoulders. Cross the South Branch of Tionesta Creek via the FR 148 bridge. Parking and dispersed camping are available on FR 148 near the creek.
Fishing is excellent.
The next area of big rocks are at the Tionesta Scenic Area. Big timber much of it 300-400 years old, is yours to enjoy. For an outstanding view of the 1985 Tornado Swath take the short loop road to the viewing platform. Hemlocks and small waterfalls. On the trail, note a Red Pine plantation just west of the RR tracks.
