Mountain Park is home to Indian Spring, a spring Cherokee Indians believed had medicinal, life-sustaining value. Braves would leave their homes in the hills and travel miles to retrieve Indian Spring water for an ailing Cherokee chieftain. Local lore holds that those who find their way into Mountain Park and the area of Indian Spring are drawn by the powers of the healing waters. Interestingly as well, until the 1960s, Indian Spring was the only source of water for many residents.
For more than 25 years before incorporation in July 1927, Mountain Park largely revolved around life in the summer cottages of Atlanta's elite. Some of these cottages had, and still have, special names including The Buzzard's Roost, The Owl's Nest, Paradise and Nuth-in-Much. More recent residents have continued the tradition of naming their homes, too.
