Sandbanks Provincial Park's boat ramp sits within the Outlet River A Campground, southwest of the bridge over the Outlet River, near where the river opens onto Lake Ontario.

It is a seasonal facility suitable for boats under 18 feet in length; the water at the launch is notably shallow, making it better suited to smaller craft such as canoes and kayaks than larger powerboats.

A small parking lot directly across the street is designated for vehicles with trailers. Boaters launching here can access East Lake via the Outlet River, as well as Lake Ontario.

Those wishing to explore the West Lake dunes shoreline may find alternative public launches outside the park more practical.
