HIGHLIGHTS: The Appalachian Trail in Pennsylvania covers 229 miles of trail and starts just 0.2 miles north of the Pen Mar State Park. Pennsylvania is notorious for its foot-bruising, boot-destroying rocks, and there are some fairly strenuous climbs in and out of gaps in the ridges of the Allegheny Mountains. This short section covers only a few miles from the Pen Mar State Park to PA 16 between the towns of Waynesboro and Blue Ridge Summit. Laid Back Sue and I hiked it one morning and then caught a ride into town to re-supply for the week.
