The historic cities in Maryland are delightful to explore. The state on the shores of Chesapeake Bay was one of the earliest settled by European immigrants, with cities such as St. Mary’s City and Cambridge being some of the oldest in the nation. Maryland welcomes millions of visitors every year because of the state’s central location near DC, New York and Philadelphia, even though you’ll find Maryland cities such as Baltimore and Frederick that are excellent metros to explore without leaving the state. From large and storied suburbs in southern Maryland that make up the DC metro to the idyllic coastal vacation destinations packed along Maryland’s Eastern Shore, it’s easy to see why so many travellers love visiting the Old Line State repeatedly.
