What to know

Kenilworth Aquatic Gardens stands as the only National Park Service site dedicated specifically to the propagation and display of aquatic plants. This 12-acre sanctuary is a botanical treasure, featuring over 45 ponds filled with lotus, water lilies, and other aquatic species. The gardens are nestled within the larger 700-acre Anacostia Park, providing a lush escape from the urban bustle of Washington, D.C. The site has a fascinating origin, beginning as the personal hobby of a Civil War veteran. For 26 years, the location operated as a commercial water garden before the federal government purchased the property in 1938. Following this acquisition, the facility ceased its commercial operations and was integrated into the National Park system, where it is currently administered by National Capital Parks-East. Visitors can explore the landscape via a boardwalk that leads directly into the marsh, which is recognized as the largest remaining tidal marsh in Washington, D.C. For those seeking a longer stroll, a dedicated trail runs along the Anacostia River. These paths offer prime opportunities for nature observation, allowing guests to spot turtles and frogs hopping through the ponds. Beyond the flora, the park is a haven for wildlife. The environment is ideal for birdwatching, and the park offers engaging activities for younger guests, including the Junior Ranger program and the opportunity to collect national park passport stamps at the visitor center.

Visitor tips

  • Visit the visitor center between 8:00 a.m. and 4:00 p.m. to collect your national park passport stamps.
  • Bring binoculars for birdwatching and spotting turtles and frogs in the 45+ ponds.
  • Wear comfortable walking shoes for the boardwalk and the trail along the Anacostia River.
  • Plan your visit around the seasonal hours: the grounds typically close at 5:00 p.m. in summer and 4:00 p.m. in winter.
