gsnakehill - I found out about this campground on the Internet, and I RV camped there in September 2005.
Campground Review
I really don't want anyone to know about this campground because you can usually drive up and get a site, but it is a gem with no services. This is a state campground for RVs only in a parking lot next to the beach and an inlet where one can canoe. Some sites look out on to the breachway where one can watch the fishermen, and the other sites are in rows in the back. You can ride your bike around this area and there are also restaurants close by for seafood. There are only 75 sites here with a bathroom but no showers. It is on the beach and looking out to Block Island Sound. It is beautiful. There are no reservations just first come first serve, and the maximum stay is one week. The season runs from April 15 to October 31, and rates with no services are $14 for residents and $20 for non-residents with extra charges for additional cars. This campground is south of Route 1 in southern RI in the town of Charlestown. For those with tents, or if you want more services, there is another RI state park that offers camping and swimming. Burlington State Park is just north of Route 1 in the same area.
