Ellanor C. Lawrence Park is located in Chantilly, Virginia, just north of Centreville, on Route 28. The park preserves the cultural and natural resources of western Fairfax County and has a long and complex history lasting 8,000 years. The land was originally inhabited by Native Americans, but as Europeans settled in Virginia, the land was shaped by only three families: the Browns, Machens and Lawrences. Through these periods, the land was used as a tenant farm, family homestead, and country estate until it was deeded to Fairfax County Park Authority as a 640-acre nature park in 1971. On the eastern side of Route 28, visitors can learn about the site’s natural and cultural history at Walney Visitor Center, where visitors can see the park’s several significant structures including Walney, an 18th-century farmhouse, and 19th century outbuildings and features, including a smokehouse, dairy, ice house and ice pond remnants. Cabell's Mill and Middlegate stand in the southeastern end of the park. Middlegate is an early 19th-century stone house associated with Cabell’s Mill, which was built in the 18th century. Cabell's Mill is a popular setting for weddings and is available for rent through the Fairfax County Park Authority. Middlegate is used for park administrative offices. Approximately four miles of mostly earthen trails are accessible from the Visitor Center, the pond, Cabell's Mill and the park's northern terminus on Poplar Tree Road. The trails pass through the park's diverse habitats and are popular with birders, runners, dog walkers, and families. Trail maps are available at the Walney Visitor Center. Bicycles are not permitted on most park trails except the paved or gravel Big Rocky Run Stream Trail, which begins near Cabell's Mill and ends at the Fairfax County Parkway. Fishing under state regulations and licensing is permitted in the pond and Big Rocky Run. On the western site of Route 28, the park houses playgrounds, athletic fields (including soccer, baseball, and softball fields), and a fitness trail with stations.

The Enola Gay () is a Boeing B-29 Superfortress bomber, named after Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets. On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb in warfare. The bomb, code-named "Little Boy", was targeted at the city of Hiroshima, Japan, and caused the destruction of about three quarters of the city. Enola Gay participated in the second nuclear attack as the weather reconnaissance aircraft for the primary target of Kokura. Clouds and drifting smoke resulted in Nagasaki, a secondary target, being bombed instead. After the war, the Enola Gay returned to the United States, where it was operated from Roswell Army Air Field, New Mexico. In May 1946, it was flown to Kwajalein for the Operation Crossroads nuclear tests in the Pacific, but was not chosen to make the test drop at Bikini Atoll. Later that year, it was transferred to the Smithsonian Institution and spent many years parked at air bases exposed to the weather and souvenir hunters, before its 1961 disassembly and storage at a Smithsonian facility in Suitland, Maryland. In the 1980s, veterans groups engaged in a call for the Smithsonian to put the aircraft on display, leading to an acrimonious debate about exhibiting the aircraft without a proper historical context. The cockpit and nose section of the aircraft were exhibited at the National Air and Space Museum (NASM) on the National Mall, for the bombing's 50th anniversary in 1995, amid controversy. Since 2003, the entire restored B-29 has been on display at NASM's Steven F. Udvar-Hazy Center. The last survivor of its crew, Theodore Van Kirk, died on 28 July 2014 at the age of 93.

The Steven F. Udvar-Hazy Center, also called the Udvar-Hazy Center, is the Smithsonian National Air and Space Museum (NASM)'s annex at Washington Dulles International Airport in the Chantilly area of Fairfax County, Virginia. It holds numerous exhibits, including the Space Shuttle Discovery, the Enola Gay, and the Boeing 367-80, the main prototype for the popular Boeing 707 airliner. The 760,000-square-foot (71,000 m2; 17-acre; 7.1 ha) facility was made possible by a $65 million donation in October 1999 to the Smithsonian Institution by Steven F. Udvar-Házy, an immigrant from Hungary and co-founder of the International Lease Finance Corporation, an aircraft leasing corporation. The main NASM building, located on the National Mall in Washington, D.C., had always contained more artifacts than could be displayed, and most of the collection had been stored, unavailable to visitors, at the Paul E. Garber Preservation, Restoration, and Storage Facility in Silver Hill, Maryland. A substantial addition to the center encompassing restoration, conservation and collection-storage facilities was completed in 2010. Restoration facilities and museum archives were moved from the museum's Garber facility to the new sections of the Udvar-Hazy Center.

The Mitchell-Weeks House is a "Potomac Valley style" log farmhouse first built in 1789. Descendants of builder Benjamin Mitchell lived in the house, located in Chantilly, Virginia just west of the intersection of Lee-Jackson Highway and Lee's Corner Road, until approximately 1940. Subsequent owners renovated and remodeled the house, but it currently preserves the Early American-era log front wall and stone chimneys. The Fairfax County Park Authority erected a historical marker for the house in 2003.

Sully Historic Site, more commonly known as Sully Plantation, is both a Virginia landmark and nationally registered historic place in Chantilly, Virginia.The earliest recorded claim to the land was made by the Doeg. Later the Lee family of Virginia owned the land from 1725 to 1839. Richard Bland Lee did not build the main house until 1794. Following the purchase by William Swartwort in 1838, Sully was used as a home, a working farm, or both by a series of private owners. Then in 1958, Sully was acquired by the federal government as a part of the area to be used for the construction of Dulles Airport. Today the Fairfax County Park Authority operates the site with a specific focus on the Lee family.

Schneider Crossroads is an unincorporated community in Fairfax County, in the U.S. state of Virginia. State Route 620 and State Route 609 cross here and it is located 5.3 miles northwest by road from Centreville. It contains little more than a florists' and a site called Cox Farms. Pleasant Valley Golf Club lies to the northeast, with the two other quadrants also incorporated into yet undeveloped Fairfax County Park Authority parks. As the crossroads is a major traffic bottleneck, with traffic flow formally managed by 4-way stop signs, Loudoun County, just west of the crossroads, offered over a million of the county's funds in 2012 to pay for the intersection upgrade as their residents were inconvenienced the most by the traffic problem, although the intersection is completely in Fairfax County. The Virginia Department of Transportation determined that the optimal solution was a roundabout which was built from 2015 to 2016. Although traffic is much improved, the poor nature of the two-lane Braddock Road to the east of the traffic circle is now the main impediment of east-bound morning traffic.
