TAKE THE FERRY TO THE ISLAND. A brand new feature for our parties in 2025 is the ability to take a ferry to our shows. Red & White Ferry will offer the best and easiest way to get to Gold Bar. Simply select a departure time on the ticket link, head to GATE B at the Ferry Building at your selected time and enjoy a quick 15 min trip across the bay to the doorstep of the venue. It's quite honestly the best way to get to the island. At the conclusion of the party, the ferry will run continioulsy from 9:15pm to 10:45 pm to get everyone back to the ferry building. Service for the outbound ride back to SF will be boarded on a first serve basis, your rouindtrip ticket guarantees a ride back to SF. Ferry ticket holders will be allowed to enter the Gold Bar lounge after the show is over if you don't get on the first ride.
