About Ramapo River

The Ramapo River flows through Bergen and Passaic counties along the base of the Ramapo Mountains, offering a mix of stocked trout water and some holdover fish in deeper pools. It's a larger river than most NJ trout streams with more varied structure, accessible via Ramapo Valley County Reservation. Best fished in spring and fall when water temperatures are in range for trout.
