The entrance (and exit) road for Chinn Ridge are a one-way loop beginning and ending at two different points along Sudley Road.  In the middle, there is a two-way side road leading to the parking area.

There is habitat variety all along the one-way portion - woods, field edges, and a stream. So it's beneficial to drive and stop along that road, and along the two-way section as well. You can bird just from the parking lot, or (like all of this Park), begin walking trails in multiple directions. For one example, you can walk about 0.7 mile, mostly through woods and past a stream, to the New York Monument hot spot.

On the last part of the one-way section, the road crosses a stream, with riparian habitat.

Chinn Ridge is a slight elevation rise within the Park.  The parking area along the ridge has views of fields and woods.

Manasssas National Battlefield Park is managed by the National Park Service primarily to preserve and display the rich civil war history here. At the same time, it provides a fine variety of birding habitats. There are many places to park, walk the trails, or even view some of the fields from your car. All of the extensive field areas are managed to provide a variety of mown, brushy, and succession grassland.

Manassas National Battlefield Park encompasses nearly 5,100 acres of land and includes more than 40 miles of hiking trails.

Unlike many other National Parks, this sprawling and accessible park is free - no entrance or parking fees. Many of the street entrances and parking areas have gates; but in recent years, most of the gates have remained open 24 hours. It is usually possible to bird at any time of day.
