The Deanwood Metro Station on the Orange Line is closest to the Kenilworth Aquatic Gardens entrance.  From the lower station exit go out the Polk Street tunnel to the pedestrian overpass that crosses Kenilworth Avenue.  Use the overpass to cross Kenilworth Avenue.  As you come down the overpass, Douglas Street will be straight ahead.  Make a left on Douglas Street and go to the end of the street, about two blocks.  Make a right at the end of Douglas Street onto Anacostia Avenue and enter any open gate on your left.

The Minnesota Avenue Metro Station on the Orange Line is the closest metro station to Kenilworth Park, about a mile away.  From the station go north on Minnesota Avenue to Burroughs and go left under the overpasses.  The park entrance is a few blocks from there at the end of Burroughs.  Busses run north and south along Kenilworth Avenue and are best for accessing Kenilworth Park.
