Destination guide
Washington: Free museums and the monuments at your feet
Washington, DC is one of the best-value city breaks in the country: the Smithsonian museums and monuments are free, the Metro reaches all three airports, and competition between Reagan National, Dulles and Baltimore keeps fares low.
Best time to visit: Late March–April (cherry blossoms) and September–October are ideal. Summer is hot, humid and crowded with school groups; winter is cheap and the museums are empty.
