Bull Run Mountains Natural Area Preserve occupies a series of rocky ridges and steep valleys on Virginia's northern piedmont. Straddling Fauquier and Prince William Counties, the preserve's 2486 acres are owned by the Virginia Outdoors Foundation, a state-supported organization dedicated to protecting open space across the Commonwealth. The preserve harbors outstanding examples of several forest and woodland community types, including some that are rare in Virginia. Other interesting communities occupy white quartzite cliffs and the boulder fields beneath them on High Point Mountain near the southern end of the preserve. The site was dedicated as a Natural Area Preserve in 2002.
The non-profit group, Bull Run Mountain Conservancy (BRMC), maintains public access facilities at the southern end of the preserve, including parking space and hiking trails. The group also provides interpretive and environmental education programs. For details, visit their website at www.brmconservancy.org
