The Klingle Valley Trail is a trail in the northwest quadrant of Washington, D.C. In 1990, erosion led to the closure of a 0.75-mile section of the road between Cortland Place and Porter Street.

In 2017, that portion of Klingle Road became Klingle Valley Trail, reserved for hikers and bicyclists.

Woodley Park is a neighborhood in Northwest, Washington, DC. It is bounded on the north by Woodley Road and Klingle Road, on the east by the National Zoo and Rock Creek Park, on the south by Calvert Street, on the southwest by Cleveland Avenue, and on the west by 34th Street. Adjoining neighborhoods are Cleveland Park to the north, Mount Pleasant and Adams Morgan to the east, Kalorama to the south, Woodland-Normanstone Terrace to the southwest, and Massachusetts Heights to the west. Woodley Park is served by the Woodley Park-Zoo/Adams Morgan Metro station, between Dupont Circle and Cleveland Park on the Red Line. Straddling Connecticut Avenue south of the National Zoo is a neighborhood of fine early 20th-century row houses, a throwback to the days more than a century ago when developers hoped that this wide avenue that runs northward to the Maryland border would be a boulevard lined with elegant homes. Modern-day Connecticut Avenue north of the small Woodley Park historic district, however, is now mostly filled with high rent, high rise apartment houses — although the city's height limitation restricts them to no more than eight stories, they are considered high-rise by Washington standards. To the east, the neighborhood's curved streets overhang Rock Creek Park. On the west, they bend on the slope leading to the heights of Mt. Saint Albans, the site of Washington National Cathedral. The stately rows of meticulously designed houses are preserved intact, presenting streetscapes that have changed little for nearly a century. Though busy Connecticut Avenue is always just around the corner, the residential streets are leafy, green, and serene. The neighborhood provides access to several nature trails, including Rock Creek Park, Tregaron Conservancy, and Klingle Valley Trail. On Connecticut Avenue, former row houses along the street have been converted into commercial properties, including restaurants, offices and retail shops. Two large hotels are located on Calvert Street (the Omni Shoreham Hotel) and Woodley Road (the Marriott Wardman Park hotel, the second largest hotel in D.C.). At night, the place is a hive of activity, particularly since a shuttle bus (The Circulator) now runs between the Metro stop (Woodley Park/Adams Morgan) to the heart of Adams Morgan and the U Street Corridor. Shops and restaurants lining Connecticut Ave include many chains (such as Chipotle, McDonald's, and CVS), but also many fine local restaurants and shops. The area was named after Woodley House, built by Philip Barton Key (the Uncle of Francis Scott Key) in 1801. Woodley has housed many political elites from President Grover Cleveland to World War II Secretary of War Henry Stimson. Nowadays Woodley House serves as the library and administrative building of the Maret School. The Woodley Park Community Association was established to support the in-town neighborhood quality of life in Woodley Park. It has several hundred members and works on issues of general neighborhood interest.

The Kennedy–Warren is a historic eleven-story apartment house in Washington, D.C. It is located at 3131–3133 Connecticut Avenue, N.W. between the Cleveland Park and Woodley Park neighborhoods. The Art Deco building overlooks the National Zoological Park and Klingle Valley Park, which is near the Art Deco Klingle Valley Bridge. The original main building was built between 1930 and 1931 with 210 apartments. The plans of its architect, Joseph Younger, called for a northeast wing and a south wing as well, but construction of these was stopped because of the onset of the Great Depression. The northeast wing was later built in 1935 with 107 additional apartments, as economic conditions improved in Washington. And the B. F. Saul Company, owner of the building since 1935, added the south wing between 2002 and 2004. The architect of the northeast wing was Alexander H. Sonneman, and of the south wing was Hartman-Cox. The current total number of apartments, ranging from efficiencies to three-bedroom units, is 425. The Kennedy–Warren is considered the largest and best example of an Art Deco building in Washington. In 1989, the building was listed as a District of Columbia Historic Landmark, and in 1994 it was added to the National Register of Historic Places. The newer south wing won numerous awards for the quality of its architecture, and for attention to historical detail, including the 2005 Award of Excellence for Historic Resources by the American Institute of Architects.
