Nearly cleaved in half by immense Chesapeake Bay, Maryland has a salty charm. Start your vacation in a Maryland campground near Annapolis, where 18th-century homes line narrow streets and sailboats fill the harbor. On your camping vacation, follow the bay’s meandering shoreline to discover crab-fishing fleets, wild ponies on Assateague Island and countless city attractions in Baltimore. Inland, take your RV on a self-guided driving tour of one of the Civil War’s most significant sites, the Antietam National Battlefield near Hagerstown. Farther west, take a rollicking raft trip down the famed Youghiogheny River. Use your Maryland campground as a base camp for tours of Washington D.C.
