Dyke Marsh is teeming with diverse plant and wildlife. It's one of the largest mudflats in the DC area, made up of 380 acres (1.5 km2) of floodplain, swamp forest and tidal marsh that were formed several thousand years ago.

If you enjoy birdwatching, you'll love it here! The lower Potomac lies on the migration route for many waterfowl. Over 300 species of birds have been spotted at the wildlife preserve. You might catch a glimpse of beavers too.
