Getting Here

The use of public transportation or taxis is strongly recommended in the Washington, D.C., region because parking is very limited and traffic is often heavy.

By Metrorail: Take either the Yellow or Blue Line to the Pentagon Metro Station.

After arriving at the Pentagon Station, exit the platform through the turnstile and take the left escalator to the top. Once off the escalator, veer left around the barrier and turn right into the Pentagon Visitor Entrance.

By Bus: Several public bus lines service the Pentagon Transit Center including buses operated by the Washington Metropolitan Area Transit Authority (WMATA) and Arlington Transit (ART).

After arriving at the Pentagon Transit Center, exit the bus and follow the signs to the Pentagon Visitor Entrance.

Trip Planners: Convenient public transportation trip planners for both Metrorail and Bus are available on the WMATA and ART websites.

Driving is not recommended because there is no public parking for tours on the Pentagon Reservation.

The nearest public pay-for-parking facility is located adjacent to Macy's at the Fashion Centre at Pentagon City.

Once parked, walk across Army Navy Drive, and proceed through the Hayes Street Pentagon Pedestrian Tunnel to the Pentagon South parking lot.

Walk through the Pentagon South parking lot and cross North Rotary Road to the sidewalk between the two big staircases ahead. Turn right along the North Rotary Road sidewalk and follow the signs to the Pentagon Visitor Entrance.

Taxis and Ride Share drivers can drop off and pick up passengers on the sidewalk at the right side of North Rotary Road between the large stairwells for Corridors 2 and 3.

After drop-off, walk counterclockwise around the Pentagon building and follow signs to the Pentagon Visitor Entrance.
