A favorite destination for birders, geologists, and all kinds of naturalists, Rock Creek Park is an outdoor classroom for studying nature, history, and the effects an urban setting can have on a park. This forested oasis in Washington, D.C. boasts a wealth of subjects for exploration—from flora and fauna to abandoned quarries, old mill sites, and Civil War forts—each a story unto itself. The landscape includes captivating natural features—a winding, rocky creek in the bottom of a steep valley with a stretch of rapids; patches of flat, fertile floodplains with infrequent seasonal pools and groundwater seeps; valley walls that rise dramatically with jagged rock outcrops to high ridges and bluffs; moist, fern-laden ravines, hillsides cloaked with American beech, and cobblestone-sprinkled dry hilltops dense with oak trees and mountain laurel.

How the Park Came To Be

Rock Creek Park is the oldest and largest urban national park in the United States. Recognized in the early days of Washington, D.C., as a remarkable, peaceful retreat for residents and visitors to the nation’s capital, the area was established as a national park by Congress in 1890 for the preservation “of all timber, animals or curiosities … and their retention in the natural condition, as nearly as possible.”1 Its core 1,754 acres consisted of a roughly six-mile stretch of Rock Creek with its accompanying valleys and ridges as it flows from the Maryland state line south to the Smithsonian's National Zoological Park (the National Zoo), along with two of its major tributaries and their valleys—Broad Branch and Piney Branch.2  3

Rock Creek Park administers 2,800 acres in Washington, D.C.In the years that followed, more natural areas were added to the park, including Rock Creek south of the National Zoo, other tributaries of Rock Creek, and other forested parks farther west. Historic and cultural areas, such as the Fort Circle Parks and other sites of Civil War defenses, were also added. Altogether there are now 99 distinct areas (and over 2,800 acres) that Rock Creek Park administers—nearly 7% of the District of Columbia. Even those parcels that bear unique names (such as Glover Archbold Park, Battery Kemble Park, and Dumbarton Oaks Park) are included in the interactive map of Rock Creek Park

Because of its size, Rock Creek Park offers ample space for recreational pursuits (among them picnicking, hiking, biking, jogging, horseback riding, tennis, and golf), while also functioning as a nature oasis for residents and visitors to Washington, D.C.—human AND animal.
