With more than 131 acres, Grant Park is a giant greenspace that provides a natural foil to urban living. It may not be as well-known as its sister parks, but that's OK with the runners, dog-walkers and nature lovers who make the park part of their daily routines.

Tucked just south of Interstate-20 in a neighborhood of the same name, Grant Park is Atlanta's oldest surviving park. Railroad engineer Lemuel P. Grant, for whom the park is named, donated 100 acres in 1883. An additional 44 acres were added in 1890, according to the Grant Park Conservancy. The park houses Zoo Atlanta and Atlanta Cyclorama — a Civil War museum that boasts a giant oil painting depicting the Battle of Atlanta — and some of the city's grandest old trees.

Downtown Atlanta is seen through the trees from the top of Fort Walker.

Before the trees leaf out, downtown Atlanta can be seen from the top of Fort Walker, which was part of a line of fortifications created to protect the city during the Civil War. What remains are the tell-tale berm and a historical marker.
