SF Winery Cruise
Wine is the focus of this four-hour tour, which crosses the bay aboard a vintage 1958 motor yacht that doubles as a tasting bar. Begin with onshore wine-tasting, followed by champagne toasts and hors d'oeuvres as you ferry to nearby Treasure Island and two small onshore tasting rooms. At day's end, you return glass in hand to Pier 39. Reservations essential.
