Getting There and Getting Around Washington, D.C.

Washington, D.C., is served by three major airports: Ronald Reagan National Airport (DCA), Dulles International Airport (IAD) and Baltimore-Washington International Thurgood Marshall Airport (BWI). Reagan National is closest to downtown and is conveniently served by the Metro subway system. For those with window seats, flights in and out of DCA offer views of the Piedmont-Coastal Plain boundary along the Potomac River, in addition to exciting views of the National Mall. Dulles is a roughly 45-kilometer drive west of downtown D.C. in the exurbs of Northern Virginia. Window-seaters approaching IAD can spy quarries excavating rocks from the Culpeper Basin, as well as the Blue Ridge Mountains to the west. Flights to BWI, about 50 kilometers north of downtown D.C., offer views of the Chesapeake Bay and its tributaries draining the Coastal Plain. The airport is served by a commuter train that runs to Union Station, Washington’s downtown rail hub adjacent to the U.S. Capitol. Automobile traffic in and around the city is often heavy, and a cab or rideshare from IAD or BWI into the city can take upwards of an hour. Rail service aboard Amtrak into Union Station, which is on Metro’s Red Line, may be a convenient option for some visitors to D.C.
