Parking lot in a fabulous location
If you have a self-contained RV (no pop-up/canvas; permanent toilets/water tanks), like the beach, fishing, boating, and/or windsurfing, this may just be the park for you. It is nothing more than a parking lot with no hookups and only composting toilets available, but you get access to Block Island Sound and all that it offers. Sites 58-75 are waterfront. For Rhode Island residents, the price can't be beat, and it's fair for out-of-staters, too, because of the location
No animals permitted. Generators only 8a-8p. Clam shack, marina, deli, and ice cream place nearby, but I doubt you'll want to fight the traffic on a summer day.
