Plotter Kill Preserve is a nature preserve near Rotterdam, NY. The Plotter Kill, a tributary of the Mohawk River, flows through a very rugged gorge. The forest here contains a mix of hardwoods and confiers. There are three beautiful waterfalls. The Upper Falls is 60 feet; the Lower Falls and the Rynex Creek Falls are both 40 feet.
Start on the red trail near the kiosk. Take the side trail (blue) which will take you to lookouts over the Upper and Lower falls.
Continue on the red trail which crosses the Kill on a foot bridge. You will pass by the Upper and Lower falls. The trail goes down a switchback taking you to the top of the falls on the Rynex creek. Cross the creek here.
If you have ample time, you can follow the red trail to the end of the preserve near the Thruway. There is a cascading waterfall there. I opted to turn around shortly after crossing the power lines for this trip.
