Located in the central portion of the District, Mason Mill Park and Recreation Center has many recreational opportunities in both it’s developed and non-developed sections. The park boasts two playgrounds as well as a tennis center and is an excellent place to hike, bike and picnic. The area is also a great place to observe wildlife; some of the creatures that call Mason Mill Park home include hawks, blue heron and snapping turtles. The park also has 1.8 miles of paved trail connected to it that allows visitors to enjoy scenic views. In the woods along the banks of Burnt Fork Creek and South Peachtree Creek lie the ruins of the old Decatur waterworks which are over a century in age.
Plans to revitalize the Mason Mill Park began in 1988 and the project was revamped in 2008/2009. Once the updated master plan was established, improvements have steadily been added over the years. Some additions to the area include a fenced-in, off-leash dog park as well as a nature preserve in the non-developed areas in and around the historic district. Other amenities in the plan include connecting pedestrian trials to the Toco Hill Avis G. Williams library, a treetop pavilion for wildlife observation and continuing efforts to remove invasive plant life.
