Plan a trip to Washington, D.C.
The idea to build a national capital along the Potomac River was approved by the new American government in 1790; Congress held its first session in Washington, DC, 10 years later. America's traditional political hub now buzzes with international shops and street festivals. Walk, run, or cycle by the Reflecting Pool to the Lincoln Memorial and Washington Monument. Get an eyewitness view of the history of journalism at the Newseum, and test your spy skills at the International Spy Museum. Outdoor fountains and glass-domed rooms of rainforests, flowers, and deserts await you at the United States Botanical Garden. Wander along the Chesapeake and Ohio Canal, and through the beautiful historic Georgetown neighborhood.
