Mexican Navy Tall Ship Cuauhtémoc Opens for Free Tours in San Francisco — Hours, Pier & Sunday Departure

SAN FRANCISCO — One of the most visually distinctive ships visiting the Bay this year is opening its decks to the public for several days along the Embarcadero.

The Mexican Navy sail-training ship ARM Cuauhtémoc is scheduled to berth at Piers 15–17, beside the Exploratorium, for a San Francisco visit running from Wednesday, Sept. 23 through Sunday, Sept. 27. Public open-ship tours are free through Saturday.

The most useful detail for anyone planning a visit is that the latest published boarding schedule is not the same as the first schedule announced in August. The Sept. 18 organizer update shortens Wednesday's public hours and adds a four-hour break on Thursday.

What are the latest Cuauhtémoc tour hours in San Francisco?

SF News Today is using the Sept. 18 schedule because it is newer than the original Aug. 12 announcement, which listed Wednesday until 5 p.m. and continuous 10 a.m.–8 p.m. hours on Thursday.

Where is the Mexican Navy tall ship docked?

Cuauhtémoc is visiting Piers 15–17 on the Embarcadero at Green Street, the same waterfront complex as the Exploratorium.

The Exploratorium says Muni stops directly in front of its Pier 15 building and the nearest BART station is about 0.7 mile away. The museum does not have its own general visitor parking lot, although public garages and lots operate nearby. For a high-interest free event with uncertain walk-up crowds, public transit is the simpler option.

Do you need tickets for the free ship tours?

The local organizers are advertising the open-ship period as free public tours. The latest detailed notice does not publish a paid admission price or a ticketing requirement.

What it does not yet provide is equally important: detailed boarding procedures, security screening rules and accessibility instructions. The Sept. 18 organizer notice says additional information on public access, security and accessibility will be released. Visitors should therefore check the organizer's latest notice before heading to the pier, particularly if they are bringing bags or need accessibility accommodations.

What is ARM Cuauhtémoc?

Cuauhtémoc is the Mexican Navy's sail-training vessel, used to give naval cadets practical experience at sea. Mexico's Navy says the ship has been in service for 43 years and is known as the country's maritime “Ambassador and Knight of the Seas.”

The San Francisco stop is part of the 2026 North Pacific training cruise, a 92-day voyage of roughly 9,812 nautical miles. The Navy's published itinerary includes Honolulu, Seward, Victoria, San Francisco and San Diego before the ship returns to Acapulco.

Mexican government records authorized a 332-person complement for the cruise, including officers, crew, instructors and naval cadets.

Can you watch the ship leave San Francisco?

Yes. Organizers have scheduled a farewell at the dock at 9:30 a.m. Sunday, Sept. 27, with departure planned for about 10 a.m.

The ship is then expected to head back along the waterfront and out through the Golden Gate. Because vessel movements can shift with marine conditions and port operations, anyone going solely to watch the departure should treat the published time as a plan rather than a guarantee.

Why the hours online may not match

If you have already seen a different timetable, you are not imagining it. The first San Francisco announcement listed Wednesday noon–5 p.m. and Thursday through Saturday 10 a.m.–8 p.m. A later Sept. 18 update changed Wednesday to noon–3:30 p.m. and split Thursday into two windows.

That is why SF News Today recommends checking the date on any schedule before leaving for the Embarcadero.
