Appalachian Trail - Boiling Springs to Rt 850 is a 16.4 mile moderately trafficked point-to-point trail located near Boiling Springs, Pennsylvania that features beautiful wild flowers and is good for all skill levels. The trail offers a number of activity options and is accessible from March until October.
A fairly easy 16 mile hike on the AT. It's easily done as an overnighter. This is my least favorite section of the AT that I've done so far. It was flat for the first 12 miles. The problem is, that you are never out of earshot of a road. A lot of the hiking is through corn fields and cow pastures. The last two miles are in the woods and were nice. It was mostly up hill as I recall. Double check your maps. I believe camping is not permitted for 15 miles or so along the trail before Darlington Shelter.
This is a great day trip that included a good sample of the areas different local landscapes. If slightly challenging ascents aren't something you want, I might recommend reversing the trip to start on the north side. If it's been raining make sure to plan appropriately for some soggy ground at the southern section. Thanks to the poster for the great hike.
