As we cover in our complete Sausalito Art Festival Guide there are two ferry routes that serve the Sausalito Art Festival, both convenient, with multiple purchase options:
1. Buy a combined Sausalito Art Festival - Blue and Gold Ferry ticket, and take a ferry from Pier 41 at Fisherman's Wharf directly to the Festival grounds, where there's a pier located on the shore right next to the fairgrounds at Marinship Park
2. Take a regular Sausalito Ferry from the Ferry Building or Fisherman's Wharf to Sausalito, where free air-conditioned buses run on frequent schedules between the pier and the event.
