Mallows Bay Access at Mallows Bay Park provides a boat ramp and soft launch for kayak access to explore the Mallows Bay–Potomac River National Marine Sanctuary, home to the "Ghost Fleet" of over 100 historic WWI-era shipwrecks.

The park offers gravel parking for approximately 20 trailers, portable toilets, a walking trail with interpretive signs, and picnic areas; groups of 10 or more should pre-register their paddle trips at least two weeks in advance to minimize congestion at the water access area.
