|Best Rhode Island summer beach camping – Charlestown Breachway Campground on Charlestown Beach Road in (guess where) Charlestown. Because the beach is steep, the waves are a little rough, but you can enjoy trailer camping just yards away from the beach. They have room for 75 trailers. A close second is the Ninigret Conservation Area – but there is room for fewer trailers and civilization is a bit more distant. If you are into birding, then Ninigret becomes first place.
