Mason Mill Park

As the fight against COVID-19 continues, DeKalb County parks, playgrounds, and trails are open for outdoor use. Stretch your legs and enjoy some fresh air.

We are happy that you have chosen to use the South Peachtree Creek Trail as your source of exercise during the pandemic, but please refrain from parking on Hill Park Court to enter the trail off of N. Druid Hills Road. All vehicles should use the parking provided at Mason Mill Park.


Directions, hours, and park rules

Mason Mill Park contains a 120-acre forest with a network of some of the nicest hiking and biking trails in the county. The South Peachtree Creek Trail is a multi-use boardwalk and paved route that connects Mason Mill Park, Medlock Park, the Leafmore neighborhood, and Emory University. A network of soft surface trails also provides miles of hiking opportunities within Mason Mill, Ira B. Melton, and Medlock Parks. The forest is also the location of the old Decatur Waterworks, which is on the National Historic Registry.

Directions: 1340 McConnell Dr, Decatur, GA 30033-3539
