Mallows Bay-Potomac River

Mallows Bay - A Historical Treasure

Welcome to the Mallows Bay–Potomac River National Marine Sanctuary virtual trail. A partnership between the sanctuary, the National Marine Sanctuary Foundation, and Terrain360, this website takes you on a virtual tour around the sanctuary waters and the park, all with a 360-degree view. Choose from many hiking and water trails, or other themes, such as shipwrecks or ecology. On each trail, don’t miss the clickable “hotspots” for photos, videos, and fun facts about the features of Mallows Bay. Click along the maps on each page to start your virtual tour or jump to your favorite hotspot!

The sanctuary protects and interprets the remains of more than 100 World War I-era wooden steamships, known as the “Ghost Fleet” and other maritime resources, including indigenous history and culture dating back nearly 12,000 years. The sanctuary is where history and nature come together to give a one-of-a-kind experience. There is something for everyone. You can walk the shore, see wildlife, fish, or paddle the waters. The shipwrecks are best seen at low tide. They form habitats for many fish, plants, and animals, such as ospreys, bald eagles, herons, beavers, and more.
