Must check-in at a North Maine Woods checkpoint and pay the hefty entrance plus camping fees to stay in this public land. After quite a drive, cross your fingers and hope people aren't occupying multiple sites or holding for others (we ran into this issue--sites seem to be two right next to each other throughout this area, so people would set up a tent or place their trailer in order to not have a neighbor right on top of them.) We got there late morning on a Friday and grabbed the only site that was open after being told we'd have plenty to choose from when checking in (which, I'm sure there would have been several open if people weren't occupying multiple sites). But anyway, my husband and I were happy enough with our site--just frustrated with some of the other campers making the experience more difficult than it needed to be. The weird part was everyone cleared out Saturday morning/early afternoon and we had the whole section to ourselves. Besides all that, great hiking and kayaking in the area.
