Alcatraz ferry dock: 2 of 5 pilings replaced, island closed Oct. 26 to Nov. 18

Every visitor to Alcatraz arrives by boat, and every boat ties up at one floating dock on the island. Since Monday, Oct. 26, that dock has been a work site: crews are driving new pilings to replace two of the five that hold it in place, and the National Park Service has closed the island to visitors until Nov. 18. It is the third time in 2026 that the dock has shut Alcatraz, and the last, if the plan holds. Here is what failed, why the job is squeezed into these weeks, and what you can still do on the water from San Francisco.

What is wrong with the Alcatraz ferry dock

The landing on the island is a floating barge held in position by five vertical pilings driven into the bay floor. Two of them are being replaced.

Jan. 14, 2026
One piling fails. The island closes for nine days while Alcatraz City Cruises inspects all five: two need repair, three are sound. Ferries go back in service carrying fewer people per boat, with extra vessels to keep up with ticket sales.
April 2026
A six-day closure to strengthen the three good pilings. Afterwards the boats can run at greater capacity again, enough for the peak season.
Oct. 26 – Nov. 18, 2026
Third and final phase: pile driving and full replacement of the two remaining pilings. The island is closed to visitors throughout.
Nov. 30, 2026
The San Francisco Bay Conservation and Development Commission restricts in-water work after this date. The NPS says that limit is what sets the schedule.

Pile driving in the bay is regulated, and the window for it closes at the end of November, so the replacement could not wait for the quiet of winter. Once the two new pilings are in, the NPS expects the whole floating barge piling system to last 20 to 30 years.

The repair is not paid for with public money. Under its concession agreement, Alcatraz City Cruises, the park's ferry operator, covers the cost of inspecting and repairing the dock and is doing the work itself. The company runs more than 3,200 ferry trips a year and carries about 1.5 million visitors to the island.

Reopening: Nov. 19 at the earliestThe NPS says the repairs are expected to be finished by Nov. 18 and lists the closure as Oct. 26 to Nov. 18. Several outlets give Nov. 19 as the reopening day. That is the first possible day, not a date the park has confirmed, and both the NPS and Alcatraz City Cruises warn the timing depends on the weather and the progress of the work.

Ferries and cruises still running on the Bay

None of these lands on Alcatraz. They are the boats you can still take while the island is closed.
