Hey Cyrus, Yesterday we checked out different routes into the Gettysburg Campground from Rt 15 coming from the south….(actually or the north…) The smoothest route without going through the Gettysburg square is the Rt 140 exit off 15 at Emmitsburg, MD (the next to last exit before PA). You take 140W off the ramp and go straight through Emmitsburg. It turns into PA Rt 16. You take an easy right turn onto Rt 116 E and this road goes through the town of Fairfield and then right to the campground on the right hand side…about one mile before Gettysburg.
The shortest route, without going through the square and without any hard turns, is…. Rt 116 exit off Rt 15, Hanover Rd. Go west toward Gettysburg and just after you enter town, you turn left on 6th St. After one block you turn right at the “Right turn, keep moving” sign and continue on this street (Middle St.), which turns into Rt 116 again and goes straight to the campground which is on the left about one mile out of town.
