Sandi - I found this campground in the Trailer Life Directory, and I camped there in April 2002.
Campground Review
This is a beautiful, quiet campground set in a 640-acre park along the Stono Marsh, ten minutes from the historic district of Charleston and about twenty minutes from the pier at Folly Beach. The sites are level, most are partially shaded, and almost all are situated to afford privacy. There is a beautiful little lake in the campground! The best part is that, despite being so close to a large city, the park has miles of paved walking/biking paths and rents bicycles to allow you to enjoy those paths. An excellent choice for touring the central South Carolina coastal area.
