The Tallulah Gorge is a gorge formed by the Tallulah River cutting through the Tallulah Dome rock formation. The gorge is approximately 2 miles (3 km) long and features rocky cliffs up to 1,000 feet (300 m) high. Through it, a series of falls known as Tallulah Falls drop a total of 150 metres (490 ft) in one mile (1.6 km). Tallulah Falls is composed of six separate falls: l'Eau d'Or (46 ft (14 m)), Tempesta (76 ft (23 m)), Hurricane (the tallest at 96 feet (29 m)), Oceana (50 ft (15 m)), Bridal Veil (17 ft (5.2 m)), and Lovers Leap (16 ft (4.9 m)). The Tallulah Gorge is located next to the town of Tallulah Falls, Georgia. Tallulah Gorge State Park protects much of the gorge and its waterfalls. The gorge is one of the Seven Natural Wonders of Georgia.

Just above the falls is Tallulah Falls Lake, created in 1913 by a hydroelectric dam built by Georgia Railway and Power (now Georgia Power) in order to run Atlanta's streetcars. The dam still collects and redirects most of the water via a 6,666-foot (2,032 m) tunnel sluice or penstock around the falls to an electricity generation station downstream that is 608 feet (185 m) lower than the lake, except for a few days each year. The days when water is released are very popular for recreation, such as kayaking and whitewater rafting

History
Since the early 19th century, Tallulah Gorge and its waterfalls have been a tourist attraction. In 1882, Tallulah Falls Railway was built, increasing the accessibility of the area to tourists from Atlanta and south Georgia, and the gorge became North Georgia's first tourist attraction. Resort hotels and bars sprang up to serve the tourist trade which, after the addition of the railway, swelled to as many as 2,000 people on any given Sunday. In 1883, tightrope walker Professor Bachman crossed the gorge as part of a publicity stunt for one hotel. On July 18, 1970, Karl Wallenda became the second man to walk across the gorge on a tightrope.

In the 1910s, Georgia Railway and Power began building dams on the river. The town of Burton, Georgia, was purchased and flooded as Lake Burton in 1919. Many area residents opposed the dams, including the widow of Confederate general James Longstreet, Helen Dortch Longstreet, who led a campaign in 1911 to have Tallulah Gorge protected by the state. The Georgia Assembly was unable to raise the $1 million required to purchase the gorge; Longstreet's unsuccessful campaign was one of the first conservation movements in Georgia. When the dam was completed in 1913, the roar of the Tallulah Falls (the roar could be heard for miles from the gorge) was quieted, and tourism dwindled. The park was created by Georgia governor Zell Miller in cooperation with Georgia Power.[2]

Although tourism promoters in the late 19th century described the word Tallulah as meaning "loud waters" in Cherokee, it actually has no meaning in that language. Talula is the Itsate Creek word for a small town with one mound.[3] The same word in Muskogee-Creek is talufa. Some references state that the word tallulah means "leaping water" in Choctaw. However, the Choctaw word for water is oka.

Hi,

Hope you enjoy one of the treasures in state of Georgia which not many people are aware of.
Go up and down to the bottom of the gorge could be a challenge especially in the summer heat and humidity with so many stair steps.

Best regards
