The nation's capital has a lot going for it. Iconic landmarks like the Lincoln Memorial and the Washington Monument allow you to sightsee for days. Plus, the city's plethora of Smithsonian museums gives you plenty to do on rainy or hot days. When the weather cooperates, explore some of the District of Columbia's green spaces, such as the U.S. National Arboretum or Rock Creek Park. And no visit would be complete without checking out the city's lively restaurant and bar scene.
