Coastal Plains  

The Coastal Plains region of Georgia is known for its flatlands, marshes and swamps. One of the best-known wetlands in the United States - the Okefenokee Swamp - is located in this region of Georgia. This area covers the southern and southeastern half of Georgia. It is the largest region of Georgia.

The Coastal Plains go east and south of the Fall Line. The Fall Line is the natural boundary that divides the Piedmont region from the Coastal Plains region.

The main rivers of Georgia meet in the Coastal Plains region as they make their way to the Atlantic Ocean. In this region, you can find the Oconee, Ocmulgee, Flint, Savannah, St. Mary's and Altamaha Rivers.

The Oconee River and the Ocmulgee River come together to form the Altamaha River in south Georgia. It is the largest river of the Georgia coast. The Ocmulgee River crosses the Fall Line where waterfalls and rapids  form.

The St. Mary's River forms the boundary between Georgia and Florida. It is a black water river that drains part of the Okefenokee Swamp. It begins in the Okefenokee swamp and flows into the Atlantic Ocean at Cumberland Island.


The Savannah River is a large river that has its source in the foothills of the Appalachian Mountains. It forms most of the border between South Carolina and Georgia. The river is about 350 miles long. Its mouth is at the city of Savannah.


The Flint River, named for the stones found along its shores, is the home for many types of wildlife, including the shoal bass. The river gives farmers water for their crops. The Flint River feeds into the Chattahoochee River. The Creek Indians lived in the river bottoms and valleys of these rivers.


Natural Wonders of Georgia

Three of Georgia’s natural wonders, Radium Springs, Providence Canyon, and the Okefenokee Swamp are located in the Coastal Plains.

Radium Springs has bright blue water. The springs first opened in 1927 and has now closed. When it was open, it was a favorite spot to visit. Bands played on Sundays and everyone had a good time swimming in the springs. The springs are underground water supplies that come up to the surface of the land and form a pool of water.

Providence Canyon is called Georgia's "Little Grand Canyon." It was formed from erosion 150 years ago. All of the canyons were formed by an ancient ocean. There are 16 canyons altogether.


The Okefenokee Swamp is a swamp on the Georgia and Florida border. The Okefenokee Swamp gets its name from Native American words that mean "Land of the Trembling Earth". There are hundreds of birds, mammals, reptiles, and amphibians, many of which are endangered or threatened. The St. Mary's River and the Suwannee River begin in the Okefenokee Swamp. Many of the plants found in the Okefenokee were used by the Georgia Native Americans for food and medicine.
