Just southeast of I-10, the Inman Park neighborhood also has some leafy streets for exploring.
Druid Hills This attractive neighborhood stretches from Ponce de Leon north to Emory University, and features some terrific roads for running. Some of the nicer, shaded streets with set back homes include Springdale and Oakdale. At the southern end of the neighborhood, the Olmsted Linear Park trail is a paved path paralleling Ponce de Leon for nearly 2 miles, passing through Springdale Park, Dellwood Park, Shady Side Park, and Deepdene Park. The Freedom Park Trail is just south of there.
