Dyke Marsh Wildlife Preserve

Important Notices

COVID-19 & the VBWTBefore heading out to visit a site on the Virginia Bird & Wildlife Trail, be sure to check if that site has any COVID-19 policies or closures in place. This information is typically posted on a site's own website.


Dyke Marsh Preserve features a well-developed wetland forest, expansive mudflats, and vistas of the Potomac River. Over 250 species of birds have been seen at this park. Like Jones Point, this preserve’s juxtaposition to the Potomac and urban environments makes it an oasis for wildlife. A trail runs through the wetland forest with an extensive understory that attracts fall and spring migrants. Red-eyed and white-eyed vireos, great crested flycatcher, and warblers galore can be seen in these woods after a massive migration event. The trail also runs adjacent to the extensive Hunting Creek mudflats, which is a great spot to view foraging shorebirds, and waterfowl. The lucky visitor can see up to a dozen bald eagles on the mudflats. Flowering plants throughout the site are also sure to attract a diverse array of butterflies.
