The Corio Bay – St Helens Ramp, also known as St. Helen's Boat Ramp, sits on Swinburne Street along the shores of Corio Bay, southwest of Port Phillip.

The facility features a two-lane concrete ramp with floating pontoons, making launching and retrieval straightforward for a range of vessel sizes. Boaters should note that shallow water at low tide can complicate launching.

The ramp is a well-regarded fishing destination, with anglers targeting snapper, flathead, and whiting. A shoreline platform also provides access for land-based fishing. Adjacent St. Helen's Park offers a relaxed waterfront setting for swimming and picnicking.

The ramp has been rated among Victoria's better public facilities, with boaters generally satisfied with water depth, water quality, and wait times.
