C. Lynn Keller Trail is a 6.7 mile loop trail located near Mansfield, Pennsylvania and is rated as moderate. The trail is primarily used for hiking and is best used from March until November.
Another way to access this trail is to follow the dirt road at the parking area. Look for the pond on your right, the trailhead will be on your left. A 1.5 gradual ascent will bring you to the scenic overlook.
A nice 8 mile long loop. It took me a little over 2 1/2 hours to complete the whole loop. There are two trail-heads, one located near the Corp Of Engineers Center /Stephenhouse Road (The one I used) and another in the Ives Run Campground/ Mid-state Trail. If your not in the mood to climb up a steep grade right at the get go, I'd suggest using the last of the two trail-heads as the starting point. It also seems to have a longer, but easier accent from this side. (I was walking downhill at this point, so maybe it just seemed easier)
Overall, it was a very nice way to spend an afternoon.
