Kenilworth Park & Aquatic Gardens
Washington, D.C.
The only National Park Service site grown from a water lily hobby: a Civil War veteran's daughter kept expanding her father's lily ponds until the government bought the marsh to save it from becoming a dump. Come July, water lilies and giant lotus blossoms cover acres of ponds a mile from the Anacostia — the most surprising 'garden' in the federal park system, and free.
Why Roamward picked it
Family-friendly, free, and visually stunning in bloom season (a built-in photo/check-in payoff) — anchors the Anacostia River pillar and is a genuine hidden gem most Beltway-only visitors skip entirely.
