4. Go Museum Crazy at the Smithsonian
The National Mall holds even more free and fabulous attractions through multiple museums of the Smithsonian Institution. There’s the National Museum of American History, The National Museum of Natural History, the National Air and Space Museum and the American Indian Museum, for starters, and plenty more scattered throughout the city. All in all, there are 19 Smithsonian museums, galleries, sculpture gardens and parks within Washington housing over 142 million eclectic items including the Hope Diamond, the Apollo lunar landing module, an 80 ft. dinosaur skeleton, the original Star Spangled Banner, Lincoln’s top hat, the Fonz’ leather jacket and Dorthy’s ruby slippers. You’d need a lifetime to explore it all, so save yourself the overwhelm and just hone in on a few highlights at a time. The rest can wait for subsequent visits to Washington.
