Day 1: DC Highlights in 24 Hours
National Mall & Monuments
Start at the Lincoln Memorial at sunrise — the 19-foot marble Abraham Lincoln gazes across the Reflecting Pool toward the Washington Monument. Walk the length of the Mall, stopping at the Vietnam Veterans Memorial (the black granite wall is devastating at any hour), the World War II Memorial, and the Washington Monument. The walk from Lincoln to the Capitol is 2 miles. Grab coffee and a breakfast sandwich from a food truck near the Smithsonian Metro ($6–8).
Smithsonian Museums
The Smithsonian Institution has 21 museums — all free. The National Air and Space Museum has the Wright Flyer, Apollo 11 command module, and the Space Shuttle Discovery. The National Museum of African American History and Culture is the most powerful museum in the city (free timed-entry passes required, book online months ahead). If you can only visit one, choose that. The Natural History Museum has the Hope Diamond and dinosaur halls. Allow 2–3 hours per museum minimum.
Georgetown & Monuments by Night
Head to Georgetown — DC's oldest neighborhood with Federal-era rowhouses, a waterfront boardwalk on the Potomac, and Wisconsin Avenue's shops and restaurants. Dinner at Mambo Sauce for DC's signature mumbo sauce wings ($10–14) or at Martin's Tavern — where JFK proposed to Jackie (burgers $18). Return to the Mall at night — the memorials are illuminated and the crowds vanish. The Lincoln Memorial reflected in the pool at night is one of America's most powerful images.
