Old Mill Falls is right near the Old Mill in Robert H. Treman State Park. Check out the Old Mill while you’re there. You can walk in and see the inside of the mill. The Old Mill and the falls are in the Upper Entrance. It is by no means the largest of the falls in the park, with Lucifer Falls being the main attraction. Lucifer Falls requires more effort to visit, though, and may even be closed during the winter and spring months. Old Mill Falls, on the other hand, is very easy to visit since it’s near the Upper Entrance.
1) Turn onto NY-327 W from NY-13.
2) Take the road 2.5 miles to the Upper (second) entrance. You’ll have to take a sharp left turn to enter the park.
3) Drive down to the parking lot. The Old Mill is off in a corner of the parking lot. There is no trail to the falls, as there is no hike required.
