Charleston is the oldest city in South Carolina, and has a ton of things to do. Check out the beautiful architecture of the Cathedral of Saint John the Baptist. The stained-glass windows are particularly stunning. Enjoy a boat trip out to Fort Sumter National Monument and immerse yourself in the Southern history of the Civil War. Take a tour of Middleton Place; the plantation grounds are beautiful and green even in winter. There is a restaurant on site, and you might even spot an alligator in the lake. An RV rental on a budget can make your Charleston vacation even more fantastic. Try a ghost tour, learn stand-up paddle boarding, or make the sightseeing rounds by bike.
