About this swimming hole

Below Great Falls Dam, the Caney Fork swirls into a deep, blue swimming hole that locals have jumped into for generations. Sandstone bluffs and riverside trails frame one of Middle Tennessee's classic summer scenes. Watch the dam release schedule - the river is calm and swimmable between generations.
