Los Angeles is one of the world’s great port cities, but visitors can spend days in the region without ever seeing the waterfront that helped build it.
The ports of Los Angeles and Long Beach form an enormous maritime complex where commercial shipping, naval history, historic vessels, marine science, and waterfront communities overlap.
For visitors interested in ships or the sea, the harbor offers far more than one museum.

Battleship IOWA — Best Overall Historic Ship Experience
Battleship IOWA is the largest-scale maritime museum experience on the Los Angeles side of the harbor.
The historic battleship served during World War II, the Korean War, and the Cold War, and now serves as home to the National Museum of the Surface Navy.
Visitors explore multiple decks of the actual ship while learning about sailor life, naval service, engineering, weapons, communications, traditions, and the teamwork required to operate a warship at sea.
The Life of a Sailor experience strengthens the human side of the visit by connecting the ship’s machinery and spaces to the people who worked inside them.
What visitors consistently like: Physically exploring the battleship; knowledgeable staff and volunteers; the 16-inch guns; sailor stories; authentic spaces; and views across the working port.
What to know before you go: The ship includes ladders, narrow passages, and authentic maritime conditions. Allow roughly two to three hours for a general visit.
Best for: Naval history, families, veterans, engineering fans, teens, and visitors wanting an immersive experience.

LA Maritime
Los Angeles Maritime Museum — Best for Understanding the Port
If Battleship IOWA tells the story from aboard a ship, the Los Angeles Maritime Museum provides broader context about the harbor itself.
Located on the San Pedro waterfront, the museum explores the Port of Los Angeles, maritime industries, ships, harbor communities, and Southern California’s relationship with the sea.
That makes it a great companion visit to the historic ships nearby.
The museum is open Wednesday through Sunday and currently charges just $5 for adult admission, with children 12 and under free.
What visitors consistently like: Local history, ship models, maritime artifacts, port stories, affordability, and location.
What to know before you go: The museum is relatively compact. It works well as a one-stop option within a larger waterfront itinerary.
Best for: Port enthusiasts, local-history visitors, families, maritime fans, and anyone interested in understanding how Los Angeles became a global trade center.

Lane Victory
SS Lane Victory — Best for Merchant Marine History
SS Lane Victory tells a different maritime story from Battleship IOWA.
The ship is a preserved World War II-era merchant vessel and serves as a museum and memorial to Merchant Marine sailors and Navy Armed Guardsmen.
Visitors can explore the vessel and learn about the cargo ships and crews that supported wartime logistics worldwide.
That distinction is important. Battleships may attract more public attention, but merchant vessels were essential to supplying military operations.
The Lane Victory currently recommends allowing at least two to three hours for a thorough visit. Its public operating schedule is limited, so check ahead.
What visitors consistently like: Authentic shipboard spaces, knowledgeable volunteers, merchant-marine history, machinery, and the chance to explore a historic cargo vessel.
What to know before you go: Public hours are limited, and sailing cruises remain suspended while the ship undergoes major boiler repairs.
Best for: Maritime-history enthusiasts, veterans, engineers, World War II history visitors, and people who enjoy historic ships.

Cabrillo Marine Aquarium — Best for Southern California Marine Life
Cabrillo Marine Aquarium shifts the maritime story from ships to the surrounding ecosystem.
Located near Cabrillo Beach in San Pedro, the aquarium focuses on Southern California marine animals, tide pools, coastal habitats, and ocean science.
Its proximity to the actual shoreline makes it especially effective for families who want to connect what they see inside with the natural environment outside.
What visitors consistently like: Marine-life education, family appeal, local focus, approachable scale, and proximity to the beach.
What to know before you go: This aquarium is smaller and more locally focused than the Aquarium of the Pacific.
Best for: Families, younger children, tide-pool enthusiasts, school groups, and visitors spending a day in San Pedro.

Aquarium of the Pacific — Best for Pacific Ocean Ecosystems
Across the harbor in Long Beach, the Aquarium of the Pacific offers the region’s largest marine-life experience.
Its exhibits explore species and ecosystems throughout the Pacific Ocean, making it a strong destination both for families and visitors interested in marine conservation.
The aquarium’s Downtown Long Beach location also makes it easy to pair with dining, waterfront activities, and other museums.
What visitors consistently like: A variety of marine animals, family appeal, touch experiences, immersive habitats, and its waterfront location.
What to know before you go: It is one of the area’s major family attractions, so busy weekends and holidays can draw substantial crowds.
Best for: Families, marine-life enthusiasts, younger children, ocean lovers, and visitors staying in Long Beach.
