The Window Cliffs State Natural Area covers 275 acres (111 ha) in Putnam County, Tennessee, near Cookeville. The Window Cliffs is the name of a prominent group of natural bridges in a narrow 200-foot-tall (61 m) ridge in the neck of a meander of Cane Creek. The day-use area is only accessible by hiking a 2.7 miles (4.3 km) trail. The Window Cliffs was an acclaimed destination in the nineteenth and early twentieth centuries. The area contains several state-listed endangered plants. (Ref: https://en.wikipedia.org/wiki/Window_Cliffs_State_Natural_Area)
