The Appalachian Trail in Georgia traverses the Chattahoochee National Forest. This area features rugged wilderness hiking, with highway crossings spaced about a moderate day’s journey apart. Hiking includes many steep ups and downs, but the Trail is lower here than in nearby North Carolina and Tennessee, mostly along ridges of between three and four thousand feet.
Those tempted by the southerly latitude to plan spring-break hikes in March will often be disappointed to find cold rain, sleet, and snow.

When to go April and May. September and October. Georgia is crowded with thru-hikers in March and April, and spring-break crowds make this even worse. Heat and humidity can be oppressive in July and August.
