Washington, D.C.

D.C. is a great museum city. Some of the world's most-visited museums are here, and many national galleries and museums are publicly funded, so they're free to visit. A few others, like the Newseum and the International Spy Museum, are worth paying to see. Elsewhere, in its neighborhoods, D.C. is a melting pot of cultures. During the entire month of May, D.C. celebrates its global community with embassy tours and events that take place throughout the city.

There’s always a festival of some sort going on in D.C. One of the most popular annual events is the Fourth of July fireworks celebration that takes place on the Mall. You can crowd in with the masses on a sultry July night. Or, take a boat cruise and see the fireworks from the water—the view is just as spectacular, and you can duck inside to cool off.
