From Los Angeles south to the Mexican Riviera, or from San Francisco or Seattle north toward Alaska, the Pacific side of the U.S. and Canada holds a wealth of fascinating cities and gorgeous natural wonders. The variety of cruises to choose from is also vast, whether you have a couple of days or more than a week. Many are repositioning cruises for ships moving between seasons in Alaska and the Caribbean, Mexico, or the Panama Canal. Short jaunts from LA visit Ensenada, Mexico, or Catalina Island or Santa Barbara, California, while small ships focus on areas farther north, such as Washington’s San Juan Islands.
