Okefenokee Swamp | Blackwater, National Geographic Magazine: Camping On The St. Marys RIver

Children lie in a hammock during a family camping trip along the St. Marys River, a quiet meandering river popular with local families on a 4th of July weekend. White sand beaches line the black water river as it makes it 126-mile long trek from the Okefenokee Swamp to the Atlantic Ocean, forming the border between Florida and Georgia.
