All of the free campsites on the GAP do not require reservations. Just show up and pitch your tent.
With you traveling the last week of October, the campsites will be wide open. Even during peak summer, I’ve never seen campsites full….you’ll have the trail and campsites to yourself.
That said, there are only four free sites on the GAP. Check the guides so you can find to locate them. They are located at mile markers 89, 99, 110 and 122.
All others are traditional fee based campsites and may require a reservation just to make sure you get a spot. Can’t see you not getting one though. There are way fewer thru-cyclists in late October and campsites would be glad to take your money, compared to peak
Summer. :-)
