Parks and playgrounds with restrooms in Washington DC

A pirate-ship climber by the river at the Nicholson Street end. Another play structure in the park is closed, so head for this one.

Dinosaur skeletons, animal halls, minerals and ocean displays under one roof, so each kid finds a room they want to stay in.

Wide green grounds, garden paths and a bonsai collection, so kids can run around and then look at the tiny trees up close.
