Alcatraz City Cruises ferry hits Pier 31, jolts passengers in San Francisco

A routine ride to Alcatraz turned into a frightening jolt Sunday evening when an Alcatraz City Cruises ferry struck Pier 31 while docking on The Embarcadero, shattering passenger windows and throwing people off balance. Riders described panic as the vessel hit the pier, and one passenger said a woman tumbled down a staircase as others feared the boat might be in real danger.

No injuries were reported, but the impact was enough to rattle a route that thousands of visitors and local residents treat as a dependable link to one of San Francisco’s best-known attractions. Alcatraz City Cruises said it would investigate what caused the docking incident, a process that now carries added weight because the waterfront operation is not an isolated sightseeing trip but part of the city’s core visitor infrastructure.

The Port of San Francisco says more than 1.7 million people each year travel through Pier 31 1/2 on their way to Alcatraz Island. Port documents describe Piers 31, 31 1/2 and 33 as the long-term sole embarkation site for public access to the island under a General Agreement that can last up to 50 years. That makes any collision at the berth more consequential than a simple bump against the dock: it hits the gateway for one of the city’s most heavily used tourism operations.

San Francisco has served as the embarkation point for Alcatraz visitors since 1972, and the city has continued to invest in the site. The Port approved the Alcatraz Ferry Embarkation Project at Piers 31-33 in 2018, with documents saying the work was expected to bring about $34 million in waterfront investment. The timing of Sunday’s incident also comes after the National Park Service temporarily closed Alcatraz Island from April 20 through April 24 for dock repairs, with all scheduled tours refunded, a reminder that the island’s access system has already been under maintenance this spring.

Alcatraz City Cruises’ current schedule shows multiple departures and returns every day, underscoring how many riders rely on the route and how disruptive any mechanical or docking problem can be. At a site built to move millions of passengers over decades, even a single collision can quickly raise bigger questions about training, docking procedures and how much confidence tourists should place in a ferry ride that is supposed to be one of the city’s most familiar experiences.
