Colditz Cove is one of Tennessee’s newest natural areas. It is characterized by high bluffs, rugged gorges, lush rhododendron, large trees and a beautiful waterfall. Colditz Cove is a 165-acre natural area located approximately two miles east of Allardt, Tennessee, in Fentress County. An impressive feature is Northrup Falls. This is one of Tennessee’s most stunning waterfalls, plunging more than 60 feet over a protruding rock ledge into a scenic, narrow gorge along Big Branch Creek. The waterfall is named for the family who settled here and operated a mill above the falls in the 1800s. These high cliffs and “rock houses” (cavelike overhangs) at the falls and along the creek gorge were once used by cliff-dwelling Woodland Indians over 3,000 years ago. The Woodland Indians primarily used these shelters during hunting season. Colditz Cove is also home to several, relatively rare animals including the Black Mountain dusky salamander (Desmognathus welteri), the woodland jumping mouse (Napaeozapus insignis), the smoky shrew (Sorex fumeus), the pygmy shrew (Sorex hoyi) and the southeastern shrew (Sorex longirostris).
