Antique furnishings, presidential portraits and beautifully appointed decorations make the White House (1600 Pennsylvania Ave. N.W.) a treasure trove of Americana. George Washington is the only president who never governed from the Executive Mansion, but it is one of the few buildings in today's city he would recognize. If you aren't able to take the self-guiding tour (travel requests must be submitted up to three months in advance through your member of Congress), learn more about this essential destination at the White House Visitor Center (1450 Pennsylvania Ave. N.W.).
Climb the steps of the Lincoln Memorial (2 Lincoln Memorial Circle N.W.) and contemplate Daniel Chester French's sculpture of the 16th president, seated in a colossal armchair. Then look to the east for an inspiring vista that takes in the Reflecting Pool, the green expanse of West Potomac Park and the Washington Monument.
The elevator that takes visitors to the observation room at the 500-foot level of the Washington Monument (15th Street and Constitution Avenue N.W.) is open after a three-year renovation. After enjoying the view from above, walk around the grounds and get an up-close view of the iconic D.C. landmark.
In late March or early April spring's arrival is announced by the blossoms of some 3,000 Japanese cherry trees, a 1912 gift from Japan. Their beauty is most fully appreciated on a trip around the Tidal Basin (part of West Potomac Park).
Attend a concert, play, opera or dance performance at The John F. Kennedy Center for the Performing Arts (2700 F St. N.W.). This world-class venue and living memorial to the nation's 35th president overlooks the Potomac River.

Let your imagination take you to new heights at the National Air and Space Museum (6th Street and Independence Avenue S.W.).

If you're looking for romantic things for couples to do, take a break from sightseeing—and endless walking—at the United States Botanic Garden (100 Maryland Ave. S.W.). Wander among tropical plants and flowers, then cross Independence Avenue to lovely Bartholdi Park and admire the grand, cast-iron Bartholdi Fountain.
The eco-friendly theme continues at Nationals Park (1500 S. Capitol St. S.E.). Home to the Washington Nationals (2019 World Series Champions), it's the nation's first green stadium, and it has plenty of great places to eat during games. If you're unable to catch a home game during your vacation, take a stadium tour instead.
