River park is located on the river in the city of Menominee, MI. Located next to city boat launch ($3).  It is a mature park with many medium size trees and grass roads are paved as are the sights.  There are a number of good fishing areas within the park and just outside park. The river is on one side of the park with a canal on two sides. If you bring a boat you can beach it in the park. There is also a couple of concrete pads to store your trailer in the park (limited space , 6 I believe).  Relatively close to shopping in Marrinette and Menominee. Overall a very nice park we try to stay there a couple of times a year.  Now the negative.  It is with in the city very close to the main highway / bridge. There is an active train track on the opposite side of one of the canals. One tends to come through nightly.  The park is located right on a main waterway with so there are a lot of water fowl around along with there droppings.
