Bull Run Mountain Quarry Trail is a 4.6 mile moderately trafficked loop trail located near Broad Run, Virginia that features a great forest setting and is rated as moderate. The trail is primarily used for hiking, walking, and birding and is accessible from March until November.
Spectacular views, enchanting creek, and solitude. The Bull Run Mountains are the most easterly chain in the Piedmont, and they protect the headwaters of two major watersheds: Occoquan and Goose Creek. Seven perennial streams originate in the mountains. Approximately 45 miles from Washington, D.C., the mountains are part of an important greenbelt around the nation's capital and are vital because of their proximity to ever-increasing population and development. The Bull Run Mountains are composed of rock masses of metamorphic sandstones called quartzite. They are remnants of an earlier erosion cycle that occurred when the whole Piedmont was level with their summits. The Bull Run Mountains' varied elevation, topography, soils, and hydrology contribute to a great diversity of habitats and species. These ridges provide an isolated, rugged highland terrain within the generally lowland piedmont.
Dogs are not allowed and VOF closes the trails too often.
2016-2017 WINTER CLOSURE ANNOUNCEMENT: As part of ongoing property management and maintenance efforts, the Virginia Outdoors Foundation will be closing public access to the Bull Run Mountains Natural Area Preserve in Fauquier and Prince Williams counties for the winter season starting on December 1.
VOF will use the closure as an opportunity to improve the preserve’s wayfinding and interpretive signs, conduct deer management activities, and address erosion on trails, which are especially vulnerable during the winter months.
The need for more active management of the preserve has increased in recent years as the number of visitors to the preserve has grown. Although the preserve offers hiking trails, its primary purpose as a state-designated Natural Area Preserve is the protection of rare plants, animals and natural communities. Active management is necessary to ensure that recreational use of the property does not impair these sensitive ecological resources.
VOF expects to re-open the preserve in early spring, but has not yet set a date. Updates on the closure and the anticipated re-opening date can be found on the foundation’s website: www.vofonline.org
FYI, dogs are NOT permitted on this trail
There are 5 trails with 4 being rated easy and one moderate (green). Good for the family. Slightly muddy.
Great mix of terrain; good for families
This is a great place to hike with many variations in the trail. While none of the trails are extraordinarily difficult, they do provide several attributes that make it more interesting, such as small ravines, tree roots, rocky paths, and fallen tree trunks. It's usually very quiet with not too many fellow hikers, but not too few as to make the hike eerie and creepy. This is definitely one of my favorite places to hike in the NOVA area thus far! You don't get the swarms of people like you do at Great Falls or some of the other more popular spots.
Great hiking, easy going, my three year old daughter loved it! Would have been better and more challenging if the top part/ overlook wasn't closed.
Really enjoyed exploring the mill and surrounding trails. Great, easy hiking with tons of history, well maintained trails and beautiful views.
Really beautiful setting and well maintained. Part of the trail was closed for renovation which was a bit of a bummer, but over all it was a good workout and my family had a good time.
Honeysuckle and Mountain Laurel awakened by senses. Even though the trailhead is right at 66 the noise subsided with minutes. The fern walk introduces all the varieties. Gentle creeks rippling through the trails, birds sing and gentle winds. Moderate yes. Will return yes
One of my son and I favorite parks--versatile, easy to access... I recommend giving it multiple visits during the different seasons.
