We did the GAP and C&O from June 27th July 2nd. Few people camping at the free campgrounds. Not sure about the paying campgrounds. The closer to the parking spots or small towns the more people you will see. The closer to DC the more people you will see on the trail. Carry enough water especially on the C&O, I ran out of water between Cumberland and Little Orleans and a family camping at the Campground at L O save the day. Don't rely on the stores at L O they were both closed when we got there. If you take the Western Maryland Rail Trail out of L O a resident next to the trail sells bottled water out of a cooler.
