Serenade of the Seas: 7-Night Ensenada, Cabo & Mazatlan

San Diego is a major cruise port on the Southern California coast, about 120 miles south of Los Angeles and directly on the Mexican border. The B Street Cruise Ship Terminal and adjacent Broadway Pier sit in downtown San Diego along the Embarcadero waterfront, within walking distance of the Gaslamp Quarter, Seaport Village, and the USS Midway Museum.

Ensenada sits on the Pacific coast of Baja California, 80 miles south of the US-Mexico border. It's the closest foreign port to Southern California, which makes it the default quick-cruise stop for ships departing Los Angeles, Long Beach, and San Diego on 3-5 night itineraries.

Cabo San Lucas sits at the very tip of Mexico's Baja California Peninsula, where the Pacific Ocean meets the Sea of Cortez. This is a tender port: ships anchor in Cabo San Lucas Bay and passengers ride small boats to the marina.

One of Mexico's oldest beach resorts, Mazatlan's cruise port is walkable to the historic Centro Historico with its 19th-century architecture and vibrant Plazuela Machado. The city's famous cliff divers perform daily, and miles of golden beaches stretch along the coast.
