7 lakes, from data published on each lake's page. See all states.
These lakes have at least one campground or RV park within 5 miles of the shoreline. Campground locations come from Recreation.gov (federal recreation data) and OpenStreetMap, and distances are straight-line from the nearest point on the shore, so the drive is longer. Each lake page lists every campground we found within 15 miles, with the type of site and amenities where the source gives them. Reservations, seasons and fees change, so check with the campground before you go.
