We did not have a reservation but could stay overnight on one of the tarmac RV sites next to the marina parking. Toilet and shower facilities were limited for the size of the campsite. Otherwise and okay site.
The campsite is conveniently located on junction 16 and 302. Large playground area in the center of the campground. Sites, mostly shaded, have picnic tables and fire pits. Wifi works fine and is free.
Quietly located off Highway 1 between Bath and Wiscasset, Chewonki campground is an oasis of peace and quiet. The terrain is park-like and set with chairs from which you can enjoy the stunning views on the area. We didn't use the saltwater pool although IT was tempting. The sane goes for the tennis court.
Facilities were clean and well kept.
If we would have had more time, we would have stayed longer than the one night we did.
Top marks!
Very quiet location in pine wooded area of Cape Cod National Seashore park. Friendly welcome. Large plots. Showers metered. Next door's Maurice's deli wasn't very well stocked.
