The Angel Island Ferry Landing in Ayala Cove offers regular passenger ferry service to Tiburon and San Francisco. The Angel Island to Tiburon Ferry provides a 15-minute crossing of the Racoon Strait to the Tiburon Ferry Terminal. The island is car-free, providing safe trails to hikers and bikers. Unlike the Tiburon and Sausalito ferry piers, private boats can moor at Ayala Cove Pier under Angel Island State Park's rules. Late in the day, lines can grow long, and on busy dates, visitors may be left waiting at the pier when the ferry reaches capacity.

This island is the largest in San Francisco Bay, with a long history. It has been a hunting and gathering location for the local native tribes, a haven and supply stop for Spanish explorers, a cattle ranch, a place to process hundreds of thousands of immigrants, and a refuge for the military dating back to the Civil War era, up to the 1960s. The island's transition into a California State Park took over to protect the remains of the former immigration and quarantine stations, as well as military defense installations, and allow visitors to enjoy this beautiful hidden gem surrounded by the urban Bay area. Ayala Cove is the landing area for Angel Island State Park and is only accessible by ferry. It is a passage from Tiburon or a longer ride from San Francisco. From here, the entire island is car-free and reserved for hikers and bikers to explore this fantastic island.
