Beautifuk falls at Rock Island State Park in Tennessee. I live in Cookeville,TN so by auto follow this: take Hwy 111 to Sparta.
From Sparta take Hwy 70S toward Doyle, Walling, Rock Island and Mcminnivlle. Before reaching Rock Island there will be a small sign on right side of road stating: "twin falls". Turn right at sign and follow winding road to the falls.
