At Mallows Bay-Potomac River National Marine Sanctuary, the synergy of history and nature provide a truly unique experience. There’s something for everyone, whether you prefer to walk the shore, view wildlife, fish, or paddle the waters. The ships emerge at low tide and provide habitat important to osprey, bald eagles, herons, and an array of fish, plants, and animals.
