Phoebe by Julia FlanaganSponsored by Prince William Conservation Alliance and Prince William Streams and Trails Coalition

Ten years ago we led the first hike down the Occoquan Greenway Trail from McCoart Government Center to the Town of Occoquan, beginning a community effort to improve conditions and open the trail to the public.

Today, about 2.4 miles of contiguous trail is available for hiking, from Lake Ridge Park to Cotton Mill Drive.  

On October 28, we will hike about 7 miles, beginning at Lake Ridge Park and ending in the Town of Occoquan about three hours later. Transportation back to your car at Lake Ridge Park is provided.

The trail surfaces include well-established natural surfaces, cleared paths in the woods, blacktop paths, sidewalks along streets and fair-weather stream crossings, which may include some steep banks.

Please dress accordingly – we recommend long pants, sturdy hiking shoes, a hat and long socks. Bring a bag lunch, plenty of water, binoculars, and a camera to capture the beautiful scenery along the way! Click here to read about previous hikes.
