Camp Mack's River Resort occupies a high bluff along an oxbow of the Kissimmee River at the eastern edge of Polk County, an area described as Tyson's Camp on an 1836 geological map. A pair of wealthy executives with the Coca-Cola Company – Leon Grady (L.G) Bruce and the man known as "Mr. Mack"—acquired the land in the early 20th century and created a private retreat for company employees from Tampa. L.G's wife Josie Bruce worked in the general store for many years.
