Fly from St Louis to Washington DC

Anyone living in St Louis interested in seeing the sights in the nation's capital can fly to Washington DC in less than two hours. Several flights depart daily from Lambert-Saint Louis International Airport (STL), and the plentiful long-term parking makes it convenient to get away for a while.

Attractions

DC is filled with museums that are free to the public, including the American Art Museum, the American History Museum and the Air and Space Museum, all of which are part of the prestigious group of Smithsonian museums. They're concentrated along the National Mall, a vast stretch of land that has the White House on one end and the Lincoln Memorial on the other. A number of other memorials are very moving, including the National World War II and the Vietnam Veterans Memorials. If you'd like to relax your feet, you can grab a meal or a drink at one of the trendy restaurants or bars in the neighborhoods of Adams Morgan, Georgetown or Dupont Circle.

Hints and tips

The region is served by Washington Dulles International Airport (IAD) and Ronald Reagan National Airport (DCA). The Metro is clean and convenient, and it saves you from navigating busy streets like Connecticut and Pennsylvania Avenues by car. Many visitors come in March and April to see the cherry blossoms and take part in the Cherry Blossom Festival, and they're usually greeted with pleasant temperatures in the low 60s during the day.
