Every Smithsonian museum in Washington, DC — the Air and Space Museum, Natural History, American History, the National Zoo, and more than a dozen others — is free every single day, no tickets or membership required (a couple of popular spots use free timed-entry passes). It's the world's largest museum complex, permanently free by design, making DC arguably the best budget family trip in the country.
