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
Park Hours: Dawn to dusk
Meet the Ranger
DeKalb County Park Naturalist, Jonah McDonald, is stationed at Mason Mill Park and leads nature programs, coordinates volunteer activities, and serves as point person for safety and maintenance at the park. Before working for the county, Jonah ran outdoors programs for independent schools, led history tours, and wrote a hiking guidebook about Atlanta-area trails.
