The Navesink River in New Jersey is a broad, brackish tidal river approximately eight miles long, connecting to Raritan Bay near Sea Bright. Its character is more like a large lake for much of its length, with generally negligible current, though it can become choppy due to wind exposure across its wide sections. The primary exception is the narrow channel near Sea Bright where tidal currents become very strong and boat traffic is heavy, making it a zone paddlers should avoid. The river's water quality is generally clean, especially in contrast to the nearby Swimming River. Multiple public access points facilitate paddling, including specific launches at Red Bank, Fair Haven, and Rumson, with Maple Cove in Red Bank noted as a sandy launch with a short walk from parking. The Oceanic Marina in Rumson offers kayak and paddleboard rentals, with services typically available from spring into mid-November. Paddling the western section towards the Garden State Parkway is recommended during high tide, as low tide exposes mud patches in the marshlands. A trip eastward towards the Oceanic Bridge and the ocean involves significant tidal currents; one account noted a difficult paddle against the current on the return leg, suggesting careful timing is required. The riverbanks offer views of impressive estates, the Red Bank skyline, and natural marsh areas. Wildlife includes various bird species such as seagulls, geese, swans, herons, and blue jays. Motorboat traffic is generally not too bad except in the constricted area near the bay. Facilities vary by launch, with some offering boat ramps, parking, and seasonal bathrooms.
