*The Commander of USS Constitution held a Public Lottery providing opportunities for the public to join the crew on board the Ship for the Independence Day cruise. The lottery was held in early Spring 2025 and is currently closed. All other events are by invitation-only and have been determined for 2025. The public is encouraged to view the Ship from various vantage points throughout Boston’s harbor.
All underway dates are subject to change or cancellation, at any time and at the discretion of the U.S. Navy.

View the Ship from shore! Here are the best places to see it:
The public can see “Old Ironsides” depart and return from the pier at Charlestown Navy Yard. Traditionally, the Ship departs at approximately 10:00 am and returns between 1 pm – 2 pm.
South Boston’s Castle Island is the location of a 21-gun salute around 11-11:30 am. The public is welcome at this South Boston location where crowds traditionally gather.
Additionally, the Ship can be seen from points along the Boston Harborwalk.
