The Great Valley Grasslands State Park boat access site provides a convenient entry point for paddlers and small boaters on the San Joaquin River. Located just off Highway 165 near Stevinson, the access features a paved boat ramp for launching kayaks, canoes, and lightweight motorized craft.
The San Joaquin River at this location is a broad, slow-moving waterway ideal for peaceful flatwater paddling. Boaters should be aware of the river's size and plan accordingly, as the wide channel can be exposed to wind. Nearby recreation areas like the San Luis National Wildlife Refuge and Grasslands Wildlife Management Area offer opportunities for exploring the diverse wetlands and grasslands surrounding the river.
While the park has limited developed facilities beyond the boat ramp, it provides a valuable access point for those looking to experience the San Joaquin River's tranquil waters. Paddlers and boaters should check for any seasonal closures or other use restrictions before visiting.
