The Allegheny River and Justus Trails can be accessed from several trailheads:
Oil City Trailhead - From PA Route 8, cross the Allegheny River at the Petroleum Street Bridge (the first bridge if entering from the south, the third if entering from the north) and make a right turn at the second stop light onto West First Street. The trailhead entrance is 1.6 miles from this light, adjacent to the GPU Building, across from Venango Campus of Clarion University. Parking is 1/4 mile from the street on a tar-and-chipped surface. Look for the yellow gate at the trailhead. The portion of this trail from Oil City to Franklin is designated the Samuel Justus Recreational Trail. The trail is marked through Oil City and can be accessed from a number of Oil City parking lots on the trail. GPS N 41 24.50 W 79 43.89
