The Kenilworth Aquatic Gardens are a series of ponds set into the tidal marshlands on the upper Anacostia River. The ponds are set up to grow waterlilies and lotuses, but when I was there they were mostly inhabited by ducks, geese, heron and one sneaky little turtle.
The park is a bit hard to find and is bordered by a huge government housing project. That, plus the fact that they are not really accessible by public transit make the gardens a quiet place to visit on weekends that normally see big crowds at places like Great Falls.
Naturally, amid all of this scenic beauty I was most amused by this garbage can that looked like R2D2.
