Another set of shots dug up during my film scanning project, I went to these in 1992 with my father. Dunn mentions these in the Hudson Valley book but says they are inaccessible. When I was there, I didn't notice any posted signs, and we just parked along the road and walked down. The situation could have easily changed since then, of course, considering I was there almost 20 years ago. Then again, my father knew many different people from his job and could very well have had permission to go in there, I don't really know. In any case, here's the shots I took back then, on semi-decent film with a semi-decent camera on a nice spring day.
From what I remember of these, the stream splits many times and flows around and over many drops along the course of the falls, so there's not one spot where you can see the whole thing.
No map since I don't know the accessibility situation, but a simple search on the town name will tell you where they are.
