How long does it take to get through the Aquarium of the Pacific?

Size and layout

The Aquarium of the Pacific covers more than 360,000 square feet, according to the official tourism board Visit Long Beach. That space is spread across 19 major galleries and exhibits. There is no published “average visit time” from the aquarium, but visitors can enter at their reserved time and stay for the remainder of the day — tickets are valid from the selected hour onward (Aquarium of the Pacific Ticket Policy).

Factors that affect your time

• Reservations on weekends/holidays: The aquarium requires advance reservations on weekends and holidays, which helps manage crowd flow (Aquarium tickets page).
• After-hours events: Special programs like Aquarium After Dark run longer than a standard visit but require separate tickets.

The pattern: visitors should allocate at least half a day for a complete experience.

Is the Aquarium of the Pacific the biggest aquarium in California?

Size comparison with Monterey Bay Aquarium

Visit Long Beach describes the Aquarium of the Pacific as the largest aquarium in California (Visit Long Beach). However, the Monterey Bay Aquarium is often cited as larger in total water volume. The Aquarium of the Pacific holds more than 500 species, while Monterey Bay’s animal collection is also extensive. The official ranking depends on how “largest” is measured — floor area vs. water volume.

Ranking within Southern California

For Southern California specifically, the Aquarium of the Pacific is the largest by floor area (360,000 sq ft) and by the number of exhibited species. Other notable aquariums in the region include the Cabrillo Marine Aquarium and the Birch Aquarium, but none match its scale.

What can you see at the Aquarium of the Pacific?

Pacific Ocean galleries and key exhibits

The aquarium is organized around three major galleries: Southern California/Baja, Northern Pacific, and Tropical Pacific. These contain a mix of open-ocean tanks, kelp forest displays, and coral reef habitats. A downloadable visitor guide (available in English and Spanish) lists all current exhibits (Aquarium of the Pacific Visitor Guide).

Special experiences

• Shark Lagoon – a touch tank where visitors can interact with bamboo sharks (Visitor Guide).
• Sea Jelly Dreamscapes – an immersive jellyfish exhibit (opened in 2025).
• Touch tanks for rays and other marine life.

The catch: some special exhibits may require additional time or separate admission.

What are the best tips for visiting the Aquarium of the Pacific?

Best times to visit to avoid crowds

Weekdays and the first hour after opening (9:00 AM) tend to be quietest. The aquarium requires reservations on weekends and holidays, so capacity is controlled, but expect larger crowds (Aquarium ticket policy).

Parking, hours, and ticket strategies

Parking is available in the adjacent structure at 99 Aquarium Way for $8 per day with validation (Aquarium parking page). Credit cards are accepted. General admission tickets start at $34.95 for adults when purchased online; buying online also secures your reservation time (Tickets page). Children under 3 do not need a ticket.

Insider tips for date night and adults-only events

The aquarium hosts monthly “Aquarium After Dark” events for guests 21 and older. These events feature live music, cash bars, and extended access to exhibits. Tickets often sell out, so advance purchase is recommended. Check the official events calendar.

What this means: choose your visit type based on crowd tolerance and budget.
