We are committed to the safety and health of our citizens. As the fight against COVID-19 continues, all Naturalist-led programs are suspended but county parks remain open for outdoor use. If you visit a park or any other public location, follow CDC guidance on how to protect yourself, including recommendations for social distancing.
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.

Meet the Ranger
DeKalb County Park Naturalist, Jonah McDonald, is stationed at Mason Mill Park and leads nature programs that are open to the public, 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. Though Naturalist-led programs are suspended during the COVID-19 pandemic, you can follow Ranger Jonah on YouTube, Facebook, or Instagram!
