Located in Warren County, Tennessee is a hidden gem called Rock Island.
Rock Island was created when the Army Corps of Engineers dammed the Caney Fork River in the early 20th century to help provide hydroelectric power to Nashville. The resulting reservoir has steep wooded banks leading down to the lake with lots of generations-old vacation homes taking full advantage of floating boat docks and water activities. Twin Falls is a striking cascade near the powerhouse where water flows out of an underground cave before falling 80ft into a pool below.
Hiking trailes will take you right up to the falls and the caves.
