This is a really nice waterfall to visit, near Mendota, Virginia. I can't find a source to back me up on this, but I've heard its height is about 65 feet. It looks about that, to my untrained eye at least.

This Google Map will get you to the correct road; however, it calls it "Abrams Falls Rd". The only sign posted at the end of this road reads "634". Once you get to 634, turn onto it and follow it past a couple of houses, for no more than a mile, until you reach a gravel parking lot. Once you park, there will be a trail at the end of the parking lot, your side of the creek. Follow this trail along the bank above the creek. It's about a 15 minute hike, and pretty easy with the exception of a couple of rough spots where it would be easy to lose footing and go tumbling down the bank, but nothing the experienced and cautious hiker couldn't handle.
