This scenic section of the Bull Run Occoquan Trail runs through Hemlock Overlook Regional Park and connects to some of the other trails in the park's network. There is a pretty cool view from the remains of the old dam at the southern end of this trail section.

The Rocky Run Stream Valley Trail runs from the Fairfax County Parkway to Ellanor C. Lawrence Park. It's 4.6 miles long, and the trail has a mix of asphalt and stonedust surfaces. It is a great tree-lined route with bridges, stream crossings, fairweather crossings, and paved swales. For most of its length, the trail follows Rocky Run Creek, and due to the fact that certain sections are of stonedust, it is best done on a bike with decent tires or on a gravel bike.
