The South Boat Ramp at Moro Bay State Park provides access to the Ouachita River and is located at the park's marina facility, which offers gas, boat slip rentals, and a full-service store.

The ramp accommodates various watercraft including motorboats, kayaks, and canoes, with ample parking available nearby for vehicles and trailers.

The marina is the only facility on the lower Ouachita River in Arkansas offering gas and slip rentals, making it a convenient access point for both day-use and extended paddling or boating trips.
