The Accokeek Foundation Boat Dock at Piscataway Park provides free public access to the Potomac River for passenger boats, with water depths of approximately 6 feet at high tide and 3 feet at low tide.

The dock is accessible via stairs (not universally accessible) and is located near the Saylor Grove fishing pier and kayak launch facilities.

Note that fishing is not permitted at the boat dock itself, though equivalent accessible fishing facilities are available at the nearby fishing pier.
