Trail is prone to seasonal closures, please call ahead to confirm that it is open. 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.

this was very hard to follow. this particular image is of the green trail (or should I say NEW green trail). the original trail up to the cliffs has been closed since 2015. this new trail crosses several other trails and is not clearly marked or well maintained. several trees down and had to walk through the river several times. paths to the old Mill all closed yet you can see it from a distance. all information plaques about Mill and well taken down. I missed the cemeteries as they are on the red trail. VERY DISAPPOINTING

The beginning and end of the green trail we were flooded with mosquitos and sounds of 66. But the other 3/4 of the trail were peaceful and lovely. Lots of birds and chirping bugs. We were also visited by a darling fawn. Nice morning.

We drove out to this trail because we were looking for a moderately long hike (4-6 miles) with a fair amount of elevation (700-1000 ft). The trail was interesting but just as it started to get somewhat strenuous (what we were hoping for), we ran into a "trail closed" sign. The highest parts of the trail -- the part that takes you to the top of the mountain -- is closed. It was disappointing. The lesson here is always call the park service to make sure the status of the trails beforehand.

The mountain peak is closed for restoration.

Part of the trail was closed. There were multiple versions of the map which made it confusing on where you were going. This hike is pretty easy and would be a good trail to run on.

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

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.

shame they had to close this... hopefully once the trail repairs itself it will open up again.

one of our favorite hikes, no small effort, but definitely a great beginner hike for kids to an amazing payoff of an overlook. even you don't go to the top, there are a lot of great loops and a ton of really cool historical markers including the old mill and 150+ year old graveyards.

Trail beyond the Conservancy property to the overlook is closed.

This is one of my favorite hiking areas in Northern Virginia because of its convenient location and the ability to tailor a hike that suites your time constraints.

A large network of trails wind through the property, which is maintained by the Bull Run Mountain Conservancy. This means you can plan an easy hike with the kids that will take less than an hour, or you can plan to spend 4-5 hours winding through the trails. Unfortunately, since they've closed the trail that leads up to the cliffs, some of the difficulty has been taken out of this area.

A number of ruins, old graveyards, and Civil War historic markers dot the trails and make it an appealing adventure for occasional hikers or nature walkers.

The appeal of this location means it's frequently crowded on weekends, so arrive early. Also, some of the trails get rather muddy after a good rainstorm, so plan your footwear accordingly.

The top part of the trail is still closed off and we actually got off the trail a number of times onto other trails. So, if you want to stay on a particular trail, it's a little tricky, but if you just want to have a great afternoon criss-crossing around the mountain, it's great! Not hard or technical, but anough ups/downs/obstacles to make it fun. I've been there a number of times, and each time see something new. Yesterday we ran across an old family cemetery from the 1800s! My son and I covered 5.1 miles in 1hour 40 minutes -- with lots of stops for pictures and looking at spiders, etc. There's great canopy coverage so even though it was a sunny day it was very pleasant on the trail. The trails are well maintained and there are blazes which are easy enough to see. This is a trail system worth doing at different times of year because the experience changes completely! The only bummer to me is that there are no dogs allowed. This would be a perfect hike for the pooches!

it wasn't that bad of a hike! I didn't really get to see the view during the day but at night it was amazing just star gazing and laying on the rocks. Had a ton of fun with a group of people. Worth a trail to check out.

My boys and I hiked this a few days ago. The trail that has the view is closed off. There are several trails at this location. Take a picture of the map at the entrance so you have something to help guide you. We didn't and it seemed like the trails crisscrossed several more times than the map showed and we had nothing to reference. All in all, it was a nice hike.

Awesome trail, high points been closed off for a while but still some really nice views

1. Apparently the cliff trail is closed :-( 2. The trail map on the website doesn't reflect the closed trails. Or what they have renamed things to. There is a map at the trail head that shows whats open and distances. Did red trail to yellow loop with the little one. Description says you can see a stream, but we couldn't see it. Maybe its visible in the winter.
