Long Beach has a museum scene worth exploring on its own.
But one of the most useful things for visitors to understand is that the cultural landscape does not stop at the city line.
Immediately across the harbor, San Pedro is part of the City of Los Angeles. It offers historic ships, maritime history, marine science, and waterfront attractions that can easily fit into the same trip.
Rather than thinking of Long Beach and San Pedro as separate destinations, museum visitors can treat the harbor as one connected cultural area.

Museum of Latin American Art — Best for Art and Culture
MOLAA gives Long Beach a distinctive art museum identity.

The museum is compact enough to combine with another attraction but substantial enough to justify a visit of its own for art enthusiasts.
What visitors consistently like: Focused exhibitions, cultural perspective, accessible scale, and opportunities to discover artists outside the mainstream Los Angeles museum circuit.
What to know before you go: Check current exhibitions in advance because the experience depends heavily on what is on view.
Best for: Art lovers, culturally curious visitors, couples, and repeat Southern California travelers.

Long Beach Museum of Art — Best for Art With an Ocean View
The Long Beach Museum of Art offers a very different art experience from the city’s larger institutions.
Its Ocean Boulevard location combines exhibitions with a landscaped campus and coastal setting. The museum also operates a Downtown Long Beach space focused on emerging and established artists.
The oceanfront location adds to its appeal and makes it easy to pair with lunch or a waterfront itinerary.
The museum currently operates both LBMA Ocean and LBMA Downtown, so visitors should check which exhibitions are available at each location.
What visitors consistently like: Ocean views, manageable scale, exhibitions, architecture, gardens, and the ability to combine art with a relaxed coastal day.
What to know before you go: Gallery installations can temporarily close parts of the Ocean location, so check the current status before you arrive.
Best for: Art lovers, couples, visitors wanting a smaller museum, and anyone building a relaxed Long Beach itinerary.

Vicky the dog scavenger hunt aboard Battleship IOWA.
Battleship IOWA — Best Immersive History Experience Near Long Beach
Across the harbor in San Pedro, Battleship IOWA offers one of the area’s most distinctive museum experiences.
Visitors board an actual U.S. Navy battleship and explore multiple decks while learning about naval history, sailor life, technology, engineering, and the people who served aboard ships at sea.
The museum’s location on the LA Waterfront puts it close to Long Beach, even though it sits within the City of Los Angeles.
What visitors consistently like: The ship itself, enormous guns, authentic spaces, volunteers, sailor stories, and the sense of exploring rather than simply viewing exhibits.
What to know before you go: Some parts of the ship include ladders and confined passageways. Families and visitors with accessibility concerns should review available routes in advance.
Best for: Families, history enthusiasts, teens, veterans, engineers, and visitors looking for something unlike a traditional museum.

LA Maritime
Los Angeles Maritime Museum — Best for Port History
A short distance from Battleship IOWA, the Los Angeles Maritime Museum explains how the harbor itself helped shape Southern California.
Its exhibits cover ships, maritime industries, waterfront communities, and the development of the Port of Los Angeles.
Because admission is inexpensive and the museum is relatively compact, it works particularly well as part of a larger San Pedro museum day.
What visitors consistently like: Local maritime history, ship models, port stories, affordability, and waterfront location.
What to know before you go: Think of this as a focused history museum rather than an all-day attraction.
Best for: Port enthusiasts, local-history visitors, families, and maritime fans.

Rancho Los Cerritos — Best for Local History
Rancho Los Cerritos offers one of Long Beach’s strongest historic-site experiences.
The preserved home, gardens, and interpretation introduce visitors to California’s rancho era and the transformations that eventually produced modern Southern California.
The experience is quieter and more intimate than the major waterfront attractions.
What visitors consistently like: Gardens, historic architecture, local history, peaceful setting, and the chance to step into a different period of Southern California.
What to know before you go: This is a historic home and site, not a large conventional museum.
Best for: History enthusiasts, architecture fans, gardeners, families, and visitors interested in early California.

Cabrillo Marine Aquarium — Best Smaller Family Science Stop
Cabrillo Marine Aquarium sits near Cabrillo Beach in San Pedro and focuses on Southern California’s marine environment.
For families already crossing the harbor to visit Battleship IOWA or other San Pedro attractions, it provides an easy way to add marine biology and coastal ecology to the day.
What visitors consistently like: Local marine life, family programming, approachable scale, and proximity to the beach.
What to know before you go: It is smaller than the Aquarium of the Pacific, so the two institutions offer different experiences rather than functioning as substitutes.
Best for: Families, younger children, marine-life enthusiasts, and visitors to San Pedro.

One Harbor, Two Museum Districts
Visitors staying in Long Beach do not need to choose between Long Beach and San Pedro.
A museum itinerary can move naturally across both sides of the harbor.
For art, start at MOLAA (the Long Beach Museum of Art).
For marine life, visit the Aquarium of the Pacific.
For local history, explore Rancho Los Cerritos.
Then cross the harbor for Battleship IOWA, the Los Angeles Maritime Museum, Cabrillo Marine Aquarium, and SS Lane Victory.
Together, Long Beach and San Pedro offer one of Southern California’s most varied museum areas: art, maritime history, engineering, marine science, local history, ships, and culture, all within the same harbor region.
