Of course there is the national mall and all of the amazing Smithsonian Exhibits, but when in DC don’t forget to see the White House! The White House Tour takes some preparation as you will need to seek out a pass from your states congressional office. For those visitors from abroad, please see your local DC embassy for details on acquiring this pass. Tours are offered in the early morning hours for security reasons, so it is wise to try to get your pass the day before your projected tour.
