Yes, in 2026, you can go inside the Washington Monument, but it requires timed-entry tickets. These tickets are free but highly sought after; they can be reserved up to 30 days in advance via the National Park Service's official website or obtained through a limited number of "day-of" walk-up tickets distributed at 8:45 AM. Once inside, an elevator transports visitors to the 500-foot observation deck, offering 360-degree views of the U.S. Capitol, the White House, and the National Mall. Note that the monument typically closes one day each month for routine maintenance; for instance, it is closed today, March 3, 2026. Visitors should also be prepared for airport-style security screenings at the ground-floor entry lodge before beginning their ascent.
