Wall Street Mill is a moderate two mile out and back hike to an old mill site. This mill was used to process gold from local mining operations. At the end of the trail the homestead and mill still stands and there are several old rusted cars around the area. Please leave all artifacts for future visitors to enjoy as well.

The trail can be started from the trailhead in the Barker Dam Parking Lot, pictured here, or just east of the Barker Dam area from a dirt parking lot off of Queen Valley Road.

This trail has little shade and no cell service. Always check the weather forecast before heading into the park and consider changing plans if the weather conditions are too extreme. Before hiking, tell a safety buddy where you are going and when you plan on leaving the park.
