River Island State Park features a three-lane boat ramp located in a calm cove with 20 boat-length parking spaces, making it ideal for launching motorized and non-motorized watercraft.

The cove operates as a no-wake zone with an island reef in the center—stay near the cliffs to access the main river channel and follow all navigational buoys. The park offers year-round access with camping, picnic facilities, and a nearby market for supplies.
