Located in Chattahoochee Hills Georgia, just 20 miles southwest of the Atlanta Airport, Cochran Mill Park, with 800 acres of woods, fields, and streams, features stunning waterfalls, huge boulders, rock outcrops, wildflowers, native azaleas, mountain laurel, and the ruins of 3 historic mills. In 2010, donations from almost 400 local families in the City of Chattahoochee Hills allowed the City to purchase Cochran Mill Park from Fulton County.

In 2013, a $100,000 Recreational Trails Program Grant from the Georgia Department of Natural Resources provided the funds to create a remarkable park transformation. Eight miles of new sustainable multi-use trails have been designed and constructed and ten miles of old trails have been rehabilitated. Other park improvements include a 2.5 mile Interpretive Trail, additional parking, an information kiosk, and a trail entrance arch.  An ADA handicap accessible equestrian mounting block is easily accessible from the new parking areas.

Thanks to the RTP Grant and the work of many volunteers, Cochran Mill Park now has 18 miles of sustainable multiple-use trails shared by hikers, horseback riders, mountain bikers, and trail runners.
