Big rigs stay at the bottom of the mountain where it's flat and are close together. Upon arrival the nice ladies in the office gave me a campsite map and marked 4 sites that were available, asking us to choose one and let them know which one. Sites on the mountain are in mature trees and site surface is dirt. I didn't see any hookup pedestals in the traditional sense but they are there, sometimes on the backside of a tree. Same with water. You need to look around a bit. We received great info about the local area and where to catch commuter trains to Boston. Very helpful office staff. The bath houses are old, could use some paint but are clean and checked regularly. I thoroughly enjoyed this campground. We camped at Cape Ann Camp Site in a Travel Trailer.
