St. Mary's at US 17

The St. Mary's River begins in the peat bogs of the Okefenokee Swamp in Georgia. It provides a continuous water and land corridor that extends 125 to 130 miles from the Okefenokee National Wildlife Refuge, Osceola National Forest, and Pinhook Swamp area, through the Ralph E. Simmons Memorial State Forest and large private tracts and preserves, to the Cumberland Island National Seashore, Fort Clinch State Aquatic Preserve, and Atlantic Ocean.
