The main section of the park comprises 1754 acres (2.74 mi2, 7.10 km2), along the
Rock Creek Valley. Including the other green areas the park administers (Glover Archbold Park, Montrose Park, Dumbarton Oaks Park,
Meridian Hill Park,
Battery Kemble Park, Palisades Park, Whitehaven Park, etc.), it encompasses more than 2000 acres (3 mi2, 8 km2). The parklands follow the course of Rock Creek across the D.C.-
Maryland border to connect with Rock Creek Stream Valley Park and Rock Creek Regional Park in
Montgomery County. The Maryland parks are operated by the
Maryland-National Capital Park and Planning Commission. The Rock Creek Historic District was listed on the
National Register of Historic Places on October 23, 1991. In 2014, it was named "best obscure memorial" by
Washington City Paper.
Horse Center Rock Creek Park Horse Center, founded in 1972, is located in the middle of the park near the Nature Center. The barn, run by Guest Services Inc, has 57 stalls, two outdoor rings, one indoor ring, and three bluestone turnout paddocks. The stable provides trail rides, pony rides, and lessons for the public, along with boarding for private horses. The stable primarily teaches English riding, with an emphasis on lower-level jumping and
dressage. The barn is also home to Rock Creek Riders, a therapeutic riding program for adults and children with special needs in the D.C. area. Past participants in the program include brain-injured veterans of the conflicts in
Iraq and
Afghanistan and people with
autism,
cerebral palsy, or
attention deficit disorder. The program is volunteer-run and relies on donations and contributions for funding. Previously, Rock Creek Riders has worked with the United States Mounted Police, National Park Service, Wounded Warrior Project, and the Caisson Platoon Equine Assisted Programs to provide these therapeutic riding services.
Peirce Mill Peirce Mill is a water-powered
grist mill in Rock Creek Park. There were at least eight mills along Rock Creek within what is now Washington, D.C., and many more farther upstream in
Montgomery County, Maryland. Of those eight, only Peirce Mill is still standing. It was built in the 1820s by Isaac Peirce, along with a house, barn, and other buildings. It was later owned by a son, Joshua Peirce, and a nephew Peirce Shoemaker. It became part of Rock Creek Park in 1892. The mill was listed on the National Register in 1969 as Peirce Mill. The trail remains on the west side until just south of Klingle Bridge where it crosses back to the east and leaves the park to enter the Zoo property. The Park Service began to experiment with trails in August 1963 when mile-long Ross Drive was closed to cars from 6 am to noon on Sundays, but planning for a separate trail system didn't begin until 1965, when the federal "Trails for America" report identified a trail along Rock Creek as one of many trails for the D.C. area. That same year, the "Fort Park System, A Re-evaluation Study of Fort Drive, Washington, D.C." report suggested running the Circle Fort Trail through the park. Planning for trails led to action. In January 1967, NPS announced weekend road closures in April over a 5-mile loop in the center of the park, made up of Beach, Ross, Ridge and Joyce and they announced a plan to build a trail from Military Road to the District boundary. That trail, the first hiker-biker trail in the park, was built in the summer of 1967. The crushed bluestone trail was constructed from the Nature Center, past Wise Road to a turnaround loop just southwest of Beach Drive and the D.C. boundary. Over the next few months, NPS announced plans to add additional unpaved trails along Military Road from Oregon to Beach, along Wise to Fenwick Branch, beside Fenwick Branch to the District boundary and through Pinehurst Parkway Park (most of which were never constructed). In 1968, they built a second trail along Beach from Joyce to Bingham. By 1969, the two existing northern trails were connected with a trail along Bingham from Oregon to Beach. Later that year, NPS built the final section of the loop along Military between Oregon and Beach. By 1972, NPS had paved all of these trails except the section north of Wise to the DC Boundary. The section along Military Road was originally intended to serve as part of the Fort Circle Trail, passing by
Fort DeRussy, but work on the Fort Circle Trail ended in the 1970s with only three parts, the one in Rock Creek, a section of the C&O Canal towpath and another from
Fort Stanton to Fort Mahon, completed. Farther south, a trail along the creek was extended into the park in 1972. A trail along the Potomac built prior to 1967 was extended along the Rock Creek and Potomac Parkway in 1971 and then into the park in 1972. It was built on a bridle path that dated back to the early 20th century up to the Bluff Bridge, which was built in 1934. The section of bridle path used between P and Q streets was built in conjunction with
the Pentagon, as that project needed dirt and the park service needed dirt removed. These first sections of trail were 4 to 8 feet wide with rough pavement, steep slopes, poor visibility and sharp curves. By 1977, the trail was extended to Broad Branch Road, crossing the creek at Bluff Bridge and twice on newly constructed "breakaway" bridges. NPS and cyclists have long sought a way to close the gap on the north end of the park. After a 1973 proposal to extend the trail, NPS launched a study and announced a plan to do so in 1983, but quickly retracted it. In 1980, NPS, inspired by road closures in
New York's Central Park, prepared an assessment of alternatives for a Bicycle Trail Study of the park that analyzed nine alternatives for completing the trail system, including construction of a new bike trail and alteration of the existing road network. After a period of public comment, NPS proposed expanding the weekend closure; constructing an additional of trail, designating Beach Drive north of Bingham a bicycle route and studying the suitability of a trail in that section. After years of additional study, public hearings and trial closures, NPS announced in February 1983 a plan to expand weekend closures and close Beach between Joyce and Broad Branch to automobile traffic. At first only one lane of Beach would be closed during rush hour, but after
Metro's
Red Line opened in Montgomery County in 1985, the section would be permanently closed. Six months later, under pressure from The American Automobile Association and the governments of D.C. and Montgomery County, the park service decided not to close the section of Beach. Instead, they decided to go ahead with the weekend closures and build a bicycle trail along a horse trail between Joyce and Broad Branch by 1986. But that trail was never built. As well, a high-water bridge was built just south of Peirce Mill, replacing the low-water breakaway bridge that had been washed away by
Hurricane David in 1979. By 1990, biking on foot trails or bridle paths was no longer allowed. In 1991, a high-water bridge replaced the trail bridge beneath Porter Road, the other low-water breakaway bridge built in the 1970s. The prospect of completing a bike route across the park re-emerged in the 1990s when the park was required to come up with a General Management Plan. In 1991, a loosely knit, cyclist-dominated group called "Auto-Free D.C." renewed the push to ban automobile traffic on Beach Drive. They suggested limited road closures to discourage commuters, but allow access to most locations in the park by car. When NPS failed to take up their suggestion, the group led a series of "rolling road block" protests which aimed to peaceably draw attention to the cause by disrupting rush hour traffic. Nonetheless, the protests led to some confrontations and arrests, and at one point the Military Road Bridge was graffitied with anti-automobile slogans. In 1996, NPS initiated a federally mandated General Management Plan for the park. In June 1997, NPS laid out several management alternatives, one of which would improve and expand the paved multi-use trails and add a new trail along Wise, with the police substation converted to a visitor center and bicycle rental facility. Another alternative suggested that sections of Beach Drive be permanently closed and converted into a wide multi-use trail and that Wise Road, Sherrill Drive, Bingham Drive, Grant Road, and Blagden Avenue be converted to paved trails. Both of these alternatives were less popular than the status quo. An additional alternative created by the People's Alliance for Rock Creek (PARC), a group consisting of the Washington Area Bicyclists Association, the
Sierra Club,
Friends of the Earth and 18 other advocacy groups, suggested making Beach Drive auto-free north of Broad Branch as a means of completing the trail envisioned in 1965. The plan had popular support, but no political support. Mayor Anthony Williams who had supported closure as a candidate, opposed it as mayor, citing the need to evacuate in a post-9/11 world. In May 2004, NPS proposed instead to only close the section from Joyce to Broad Branch, but again found opposition among politicians. So, in November 2005, the Park Service finalized their management plan which included no further road closures, the prospect of lowering speed limits and adding speed bumps, and improvements to the trail south of Broad Branch. However, speed limits were never reduced and no traffic calming was ever implemented. The management plan completion cleared the way for the Park Service and DDOT to rebuild Beach Drive and the trail. Despite planning that started in 2005, work on the project didn't begin until September 22, 2016. The project rebuilt both Beach Drive and the trail. The trail section between Shoreham Drive and Broad Branch was widened to , repaved and realigned; the Shoreham Drive crossing, reworked in 2006, was again improved; the traffic lanes in the Zoo Tunnel were narrowed to widen the trail through it by ; a new access to Harvard Street was built and of new trail was constructed between the Porter Street Bridge and Bluff Bridge. In conjunction with the project, the trail through the
Klingle Road intersection was redesigned to connect to the new
Klingle Valley Trail, which was built on the washed out section of Klingle Road and opened on June 24, 2017. The work on the trail south of Broad Branch was completed on January 8, 2018. Work on Beach Drive between Joyce and Bingham, which improved a short section of trail near the bridge over the creek was completed on September 27, 2019. In 2018, DDOT announced plans to rehabilitate and expand the trail within both Rock Creek Park and outside of it. Within Rock Creek Park, they will rehabilitate a section between Klingle Road and Bluff Bridge and a section on the west side of the creek south of Broad Branch Road. They will also build a new trail along Piney Ridge Road from Beach Drive to
Arkansas Avenue. Though the 2005 D.C. bicycle plan only identified a need for "an improved bicycle connection" between Broad Branch and the Maryland Line, the 2013 MoveDC Multi-modal transportation plan includes a future trail on this section. Sections of park roads have been subject to weekly closures to motor vehicles since the 1960s, though the times and locations changed. After the 1963 closure experiment, another was attempted in 1967 on Beach between Joyce and Broad Branch on Sunday mornings, but the response was not positive and it was discontinued. In 1970, NPS tried again, closing of Beach, and part of Morrow, every Sunday from 9 a.m. to 6 p.m., but was again discontinued due to a lack of use. But, in 1972, NPS tried for a fourth time, again closing Beach between Broad Branch and Joyce from 8 a.m. to 6 p.m. on Sundays and it became a permanent feature. On more than one occasion in the 1970s they experimented with Saturday closures in the summer, once to support a new bicycle concession near Carter Barron, which generated no negative response, but also little use. By 1980, they added the section from Tilden to Piney Branch Road and expanded the hours to 7 a.m. to 7 p.m. and in August 1981, they expanded the closure to Saturdays and holidays as an experiment. In August 1983 they made the closures, between 7 a.m. and 7 p.m. every Saturday and Sunday, official policy as part of the scaled back 1983 Plan. == Administration ==
