Marquis Basin Boat Ramp offers two concrete launching lanes with courtesy docks, making it suitable for both motorboats and hand-launching kayaks and canoes.

The facility includes parking for approximately 15 boat trailers, porta-potties, and picnic areas, with operating hours from 7am-10pm (though open 24 hours for fishermen).

Located at the northeast end of Blackwater Bay in Milton, this is a well-maintained public access point for recreational boating and paddling activities.
