Okefenokee Swamp. The Okefenokee is the largest un-fragmented freshwater and black water wilderness swamp in North America. It covers over 600 square miles, most of which are in southeast Georgia, but a small portion spills across the Florida border. Paddle along one of the many waterways, or explore on a guided eco-tour. Adventurous souls can reserve an overnight camping paddle permit, allowing you to slumber under the stars at one of several hammocks and shelters along the water trails.

Providence Canyon. Georgia's "Little Grand Canyon" shows the impact man has on Mother Nature. Gullies up to 150 feet reveal a rainbow of color in the earth, shining red, pink, orange and purple like a painter's masterpiece. Hikers and campers can explore the area, created by poor farming practices in the 1800s. Visit the canyon's bottom to see magnificent fossils in what used to be the ocean's floor.

Radium Springs. Radium Springs pumps 70,000 gallons of 68-degree water per minute from an underground cave. Visitors can enjoy foliage-draped surroundings and flora both indigenous and exotic to the area, but can no longer swim in the crystal clear waters. The springs derive their name from traces of radium found in the water, once thought to provide healing properties.

Stone Mountain. At 825 feet high, our monstrous monadnock is nothing short of spectacular, and the park housing this behemoth is Georgia's most popular attraction. The dome of quartz monzonite is thought to have been formed at the same time as the Blue Ridge Mountains. The exposed rock is five miles in circumference and continues underground an additional nine miles. Visitors can reach the summit by taking the walk-up trail on the west side or by the Skyride aerial tram.

Tallulah Gorge. Tallulah Gorge, located at Tallulah Gorge State Park, plummets to over 900 feet deep, and it is the deepest gorge this side of the Mississippi. Visitors must get a permit to hike to the bottom, though there is no charge. In the late 1800s, the now defunct Tallulah Falls Railway was built, quickly making the gorge one of the first tourist attractions in the North Georgia Mountains.

Warm Springs. Warm Springs is an historic district that includes FDR's Little White House and the Roosevelt Warm Springs Institute for Rehabilitation, where Roosevelt indulged in its warm springs to help with his polio. The Warm Springs Institute currently treats about 5,000 patients each year, but the waters are not open to the public.
