Tallulah Gorge is a roughly 2-mile-long, nearly 1,000-foot-deep canyon in northeast Georgia, carved by the Tallulah River through the Tallulah Dome and protected largely within Tallulah Gorge State Park. Formed by ancient folding during the creation of Pangaea and shaped further by water, it contains varied ecosystems and the endangered persistent trillium. Long celebrated as one of Georgia’s natural wonders, the gorge became a major tourist destination after the Tallulah Falls Railway arrived in 1882, then changed dramatically when a hydroelectric dam built in 1913 diverted most of the river. Conservation efforts later helped secure the gorge’s protection, and it remains a recreation and filming site.
