Smithsonian National Carousel

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

The founding documents themselves, with interactive displays that explain them. The line can run long, so go early.

Landmark planes and spacecraft overhead, and a gallery on how flight works with a plane kids can sit in. Book the timed passes first.

Galleries inside and a sculpture garden outside, so when kids are done with paintings there is room to walk among the big pieces.

Wonderplace for small kids and Spark Lab for young inventors. Check the play areas are open before you go.

Artifacts and stories from Indigenous cultures, plus the imagiNATIONS activity center where kids get to try things with their hands.
