Yesterday I visited the Great Falls National Historic Park in Paterson, New Jersey. I thought it was pretty nice and worth seeing if you live nearby. It reminded me a bit (on a greatly reduced scale of course) of Niagara Falls. We have gotten some rain recently so the Falls may have been a bit more impressive than usual. There was some spray or mist from the Falls at some of the viewing locations which was fine on a hot day but might not have been as pleasant in colder weather. There is no charge to view the Falls and parking was no problem yesterday.
I took the picture near the parking area. With a little walking you can get a closer view of the Falls from the bridge in the background and from a viewing area on the other side.
