As of 2026, the primary cruise lines operating out of the Port of San Francisco (Pier 27) are Princess Cruises and Carnival Cruise Line. Princess Cruises is a major fixture in the city, frequently using the Ruby Princess or similar ships for round-trip itineraries to Alaska (10-11 days) and the California Coast/Mexico. Carnival also maintains a significant presence, often positioning ships like the Carnival Luminosa for shorter 4-to-5-day "getaway" cruises to Ensenada, Mexico. Occasionally, luxury lines like Cunard (Queen Elizabeth) or Hurtigruten include San Francisco as a departure port for grand voyages or expedition cruises. Because San Francisco is a "home port," it offers a convenient jumping-off point for West Coast travelers who want to avoid flying to Seattle or Vancouver for an Alaskan adventure, though the "Fog City" departures can be quite chilly.
