There is a nice walking trail along the river just before it turns into Niagara Falls.

After a substantial rain fall the water is roaring over the falls. I got pretty wet trying to take this picture.

The Passaic River rushing and churning loudly to find a way around the cliffs.

The forces and the roar of the water is incredible when you get this close. Your camera definitely will get wet.

It was a perfect day to photograph the falls. The water was churning wildly.

During a drought the water recedes and exposes the rock wall beneath the falls.

The Great Falls are the second-highest on the east coast (second only to Niagara). The Great Falls thunders over a rocky ledge, 70 feet deep, about 60 feet wide to a broad basin descending 20 feet through traprock and sandstone to the City of Paterson.
Even though the falls were declared a landmark, the US Department of Parks, the State of New Jersey, and the city of Paterson have done little to beautify the area and make it a safe place to visit. We always get our hopes up for improvements, but so far nothing has happened. The wilderness in the front shows the neglect. You would never believe that this natural wonder is in the center of Paterson, New Jersey.

It is a shame that the city planners and the State of New Jersey have little regard for this natural wonder. It has been neglected for a long time and there is little hope for improvements.

This area is a landmark and in dyer need of restoration. There are posters of plans for restoration, but it has been years of neglect and no end in sight. We have stopped going there. http://www.nps.gov/pagr/parkmgmt/parkplanning.htm
