On a recent road trip through Tennessee I discovered this outstanding waterfall. The trail is a not too difficult with exception to the last nearly vertical walk on rough 'stairs'. Even then it is just a matter of taking it easy.
Jump over to my Flickr account where I have this location tagged. I highly recommend searching this waterfall out.
There was also a second fall at this location that I did not have the time to visit. I would make sure you have the time to really explore the area. Look for Short Springs State Natural Area.
