Paul's Favorite Trails.
Buck Ridge Trail - 14 mile out-and-back - Great trail
connecting Pine Grove Furnace and King's Gap state parks. Well
marked and used enough that the trail is not overgrown, but on
any given day you pretty much have the whole trail to yourself.
Parking and plumbing at both ends is icing on the cake. I like
to park at the furnace stack in Pine Grove, 7 miles to King's
Gap, lunch-bathroom-refill water, 7 miles back.
Sunset Rocks - 5/10/15 miles - A very nice overlook, plus a
half-mile of rock scrambling which is great fun (although I'm
always wary of snakes on the rocks). The trail is blue-blazed
connecting to the AT at two points; with the AT it forms a loop
about 5 miles. You can jump onto the loop by parking on Michaux
Rd. off PA233 near Pine Grove Furnace, or walk in from Pine
Grove Furnace (10 miles total) or the AT parking lot on
Shippensburg Rd (15 miles total) and do a lollipop. The Sunset
Rocks trail meets the AT just west of Tom's Run Shelter, and
east of Michaux Rd where the AT crosses Tom's Run again in a
very pretty clearing.
Flat Rock - 5 mile out-and-back - Short but keeps your
attention the whole time. A seriously steep stretch early on,
some tricky uphills with rocks, topped by a great overlook. The
trailhead is in Colonel Denning State Park so parking is not a
concern. Upon entering the park from the south, turn right on
the road just beyond the park office, then park in the lot after
switchbacking down the hill.
