The paved South Peachtree Creek Trail isn’t the longest running trail in Atlanta: it runs a single mile through Decatur’s Mason Mill Park. But this trail does rack up major points for its scenic beauty. The trail travels a good bit of its length on a raised wooden boardwalk, that winds through the forest’s treetops beside a tumbling creek.

The South Peachtree Creek Trail connects Mason Mill Park and Medlock Park in Decatur, crossing only a single, quiet neighborhood road. The trail’s first half mile is moderately challenging, descending into a railway corridor and then rolling through a hilly forest. The trail’s second half levels, traversing a raised boardwalk that meanders through the forest’s shady hardwood trees. A run along this trail isn’t long, but it’s a stunningly beautiful one, with scenic treetop views and historic structures dotting the suburban landscape. And for a longer workout, the two-mile roundtrip is easily doubled for a great four-mile adventure.
