Commuter air carriers serve much of the rest of the state. Major car-rental companies maintain branches at all three airports. We recommend flying into one of the airports and renting a car to tour Maryland. Amtrak trains on the Washington, D.C.-New York runs all stop at New Carrollton, BWI Airport Rail Station, Baltimore and Aberdeen. Greyhound provides bus service between Maryland cities and to points outside the state.
Excellent roads connect most parts of the state.
I-68 runs from West Virginia to western Maryland. I-97 runs from just west of Annapolis to the Baltimore Beltway. Traffic on the beltways can be fairly hair raising, so study your map before you set out and avoid high-traffic periods, if possible.
