When travelling the Natchez Trace Parkway through Lewis County, TN, there is a small parking area for a small scenic stop known simply as Fall Hollow. I have uploaded 6 photos describing what you'll see here. From the parking lot, it's a 100 foot walk along a paved sidewalk to a wooden observation deck. From here, you can see the upper half of the Fall Hollow Waterfall, where you can see the water tumble about 30 feet. There is a second stream right next to it that tumbles just as far and they meet just a few feet below. (See images #2 and #5.) The official paved trail stops here, but in another 5 minutes of steep hiking, there is much more to see. As you leave the overlook, and walk along the top, unless it's dry season you'll see another 30 foot waterfall of side drainage. From here you can make a steep decline to the area below and if you make a left, you get to a small bridge crossing the tiny trickle and look up at this smaller falls. (See photos #3 and #6). Still at the base but off in the other direction, you see what I think is the best site here. The two streams that we saw merge from the observation deck now free falls 20-25 feet into a small pool below. Behind this is a small grotto where you can walk behind the falls. (See photos 1 and #4.)
