Plane

The closest airport is National Airport (DCA), followed by Dulles International (IAD) and Baltimore-Washington International (BWI).

Metro

The closest Metro stop is Dupont Circle (North/Q Street Exit) on the Red Line. Use WMATA's trip planner or Google Maps (top of this page) to plan your trip via bus. However, Sunday service for both the train and the bus can be slow. Check WMATA's website for the schedule and changes due to track work, etc.  

Your GPS will direct you, and the entrance is on Decatur Street. If you'd like more details, visit the Friends' site.

Driving

Most street parking restrictions and meters are suspended on Sundays. Please do read the signs carefully.

For commercial paid lots, here are your options:

Universal South Public Parking: 2005 Florida Ave NW, just across Connecticut Avenue on the left when heading east from the Meetinghouse, between the drug store and the post office.

Universal North Public Parking: across from the side entrance to the Washington Hilton (take a left onto T Street from the first parking garage option, if that's full).

Both parking garages take credit cards.
