The Smithsonian Institution, National Mall, and nearby exhibits and attractions are a very dense collection of national treasures, indeed. Other options range from the Spy Museum to Chinatown to exotic plants at the National Arboretum to Air & Space Museum to riding electric scooters in front of the White House. Fun, educational, sometimes sobering, sometimes momentous.
