Twin Falls - Rock Island State Park
Waterfall · Tennessee
About this swimming hole
A waterfall born from dam seepage, Twin Falls pours in twin ribbons down a limestone bluff into the Caney Fork - and the plunge basin is a beloved local swim spot. It's an only-in-Tennessee oddity: an accidental waterfall better than most natural ones. The park's rugged gorge trails add more swimming downstream.
