QUANTICO, Va. — The National Museum of the Marine Corps says it will open later than usual on Tuesday, Sept. 30, 2025. The announcement, posted to the museum’s Facebook page, notes a noon opening. The museum is normally open 9 a.m.–5 p.m. daily with free admission and parking.
The delayed opening comes as Defense Secretary Pete Hegseth is slated to address a rare gathering of senior military leaders at Marine Corps University on base Tuesday. While the event is closed to the public, Potomac Local is checking whether commuters and visitors should expect heavier gate traffic or temporary changes on roads serving the base and the museum.
