Anna Ruby Falls lies in the heart of the Chattahoochee National Forest. Although often crowded this is one park you don't want to miss. The thundering rush of water flowing over the rugged cliff face is where Anna Ruby Falls marks the junction of Curtis and York Creeks. Both Creeks begin on Tray Mountain . Curtis creek drops 153 feet and York Creek 50 feet to form the twin falls. From the falls, Smith Creek progresses downhill to Unicoi Lake and then to the Chattahoochee River. It flows south, eventually joining the Appalachicola River in Florida and ending its 550-mile journey in the Gulf of Mexico.
