Washington D.C.'s Metro system is the best way to get around the city. A one-way fare is $2.00 - $6.00 depending on the time of day and distance traveled. Taxis and ride-sharing services such as Uber and Lyft are also available but can be more expensive than public transportation. It is recommended that you use public transportation during your trip to save money and time.
If you have extra time, consider visiting the United States Holocaust Memorial Museum or the National Museum of African American History and Culture. Both museums are highly recommended and offer a unique perspective on the history of the United States. If you have less time, skip the National Zoo or the National Cathedral and spend more time exploring other areas of the city such as Adams Morgan, The Wharf or H Street Corridor.
