Clifton Road, near Emory University
Freedom Parkway may boast a longer and better-known jogging path, but for serenity and cleanliness, nothing beats Lullwater Park. Lush trees provide ample shade for joggers and walkers on the two cement paths that encircle a small lake. You also can check out the posh digs of Emory University president's grand Victorian-style mansion, previously owned by Coca-Cola scion Asa Candler. No playgrounds mean your run won't be tripped up by screaming kids, but look out for amorous co-eds, who sometimes use the less-trodden dirt paths for some intensive studying.
