Union Mill and Bull Run Occoquan Trail is a 4.3 mile moderately trafficked loop trail located near Manassas, Virginia that features beautiful wild flowers and is good for all skill levels. The trail offers a number of activity options and is accessible year-round.
Caution: as this loop is marked in AllTrails today, it could be broken into a northern and southern loop. The northern loop is great. The southern loop is not actually a loop. If you follow the southern half counter-clockwise the trail will end about 2 miles in. If you continue following the AllTrails marked path from that point you will end on private property (the nearby winery) just before reaching the park's parking lot.
Aside from this problem, the trails are great. A nice bit of exercise for us and our 10 year old boxer who has had two surgeries for torn cruciate ligaments. It challenged him a few times, but he made it through and seemed to have a great time overall.
Beautiful view, well marked trails.
Beautiful trail easy for all family members
This trail is a gem tucked behind the estates of Clifton. If you live in the surrounding suburbs, this easy trail offers a quick, welcome getaway from the hustle and bustle. Beautiful groves of mountain laurel and hemlocks nestle themselves in the slopes leading down to Bull Run. The occasional rock outcropping offer the more adventurous a chance to respectfully go off trail and explore. Our sunny but cold winter walk gave us a chance to view the stream looking clearer than ever and we kept our fingers crossed that a VRE train would pass oblong the neighboring tracks. There was only one moderately steep climb in the trail that tested our lungs. Very doable for hearty preschoolers with maybe a shoulder ride or two along the way.
We parked right outside the park and took the yellow trail to blue by the water and picked the yellow trail back up. At times the trail is challenging. There are a lot of geological rocks on certain parts of the path and because of fall, there were a ton of leaves, so at times it was slippery. Fitbit showed we had climbed 32 floors. Sometimes the trail was well marked sometimes it wasn't. I only heard that gun range way off in the distance just for a short period time. This was a well traveled trail on Saturday.
Parking can be a problem since there is a busy winery next door.
Good walk down to the river and back. The doggy loves the small beaches by the river.
