For visitors in 2026, the Washington Monument typically operates from 9:00 AM to 5:00 PM daily, with the last available tour ticket usually timed for 4:00 PM. It is important to note that the monument is strictly accessible by timed-entry tickets, which must be reserved in advance through Recreation.gov. Tickets often sell out weeks in advance for peak morning and afternoon slots. During the summer months or specific holiday seasons, the National Park Service occasionally extends these hours until 9:00 PM or 10:00 PM, allowing for stunning night views of the National Mall; however, these "Evening Hours" are seasonal and should be verified on the official NPS website before your visit. The monument is closed on December 25 and July 4. Security screening at the base of the monument requires you to arrive at least 15 minutes before your ticketed time to ensure you don't miss your elevator ascent.
