The Bull Run Mountains Natural Area Preserve is a rugged mountain range in northern Virginia offering diverse ecosystems, rare plants, and scenic hiking opportunities amidst a largely undeveloped landscape.
Located in Fauquier County, Virginia, the Bull Run Mountains Natural Area Preserve protects one of the northernmost examples of the Blue Ridge Mountains foothills within the state. The preserve covers rolling ridges, steep slopes, and narrow valleys that rise to an elevation of approximately 1,300 feet. It features a complex habitat that includes forested slopes, rocky outcrops, hardwood cove forests, and serpentine barrens. This diverse terrain supports several rare and endangered plant species, including the southern Appalachian rare plants like Torrey’s mountain mint and the dwarf larkspur.
The preserve's geology, shaped by ancient metamorphic rocks and serpentine soils, creates unique conditions for unusual flora that are not commonly found in surrounding lowlands. Wildlife includes small populations of black bears, white-tailed deer, and a wide variety of songbirds and other native fauna. The area is largely undeveloped, with access limited to several hiking trails that offer views of the Piedmont region, birdwatching, and wildflower observation. Visitors can explore steep wooded trails like the Bull Run Mountains Trail or the Blue Trail, which traverse through mixed hardwood forests and rocky ridges. While camping is not permitted, the preserve draws hikers and naturalists interested in exploring a relatively untouched natural area close to the Washington, D.C. metropolitan region. The Bull Run Mountains Natural Area Preserve is managed by the Virginia Department of Conservation and Recreation to ensure the area's ecological integrity and provide low-impact recreational opportunities.
