When you’re in San Francisco and looking for a family-friendly, educational outing, the Aquarium of the Bay at Pier 39 often pops up as a popular choice. For $28 per person, you get a general admission ticket that grants you access to all the main exhibit areas for about two hours. The best part? You can explore at your own pace, making it flexible whether you’re tight on time or want to linger with the fascinating marine creatures.
Two standout features for us are the walk-through glass tunnels—where schools of anchovies and glowing jellyfish swim overhead—and the focus on local San Francisco Bay marine life. These exhibits offer a surprisingly immersive experience. However, a potential downside is that some visitors find the size a bit underwhelming and feel that the exhibits could be more diverse for the price. This experience suits travelers who enjoy self-guided visits, especially those traveling with children or who love learning about local ecosystems firsthand.

A Deep Dive into the Experience
While in San Francisco, here are other experiences we've covered
Location and First Impressions
The Aquarium’s position at Pier 39 makes it incredibly accessible for visitors already exploring the bustling waterfront. It’s close to sights like the Fisherman’s Wharf, the famous resident sea lions, and bustling eateries. When you arrive, the check-in process with a mobile ticket is straightforward, though some reviews highlight issues with ticket scanning, especially if tickets are purchased online via third-party vendors like Viator.
Exploring the Exhibits
Once inside, your general admission ticket grants access to all the main exhibits, which focus heavily on marine life of the San Francisco Bay and nearby Pacific waters.
The Discover the Bay exhibit is quite engaging, especially if you’re curious about why anchovies tend to swim in schools, or what life looks like for a freshly-hatched skate. It’s a great spot for kids and adults alike. The exhibit showcases some of the bay’s brightest creatures, such as green moray eels and orange garibaldi, California’s marine fish.
The Under the Bay Tunnel is undoubtedly the highlight. Walking through a 300-foot-long clear glass tunnel, you’ll find octopuses, moon jellies, Pacific sea nettles, and even shark species like leopard and soupfin sharks swimming just overhead or around you. Several reviewers mention the thrill of feeling surrounded by marine life in the tunnel—and how the experience is enhanced by the vibrant, lively environment.
Interactive and Educational Features
The aquarium also offers interactive exhibits, and some reviewers praised the friendly staff and attentive employees. One noted, “Everyone was so friendly,” which adds to the overall welcoming atmosphere. Although no specific guided tours or narrated experiences are part of the standard ticket, the self-guided exploration allows you to linger at exhibits that interest you most.
The Size and Content — Is It Worth It?
Reviews are mixed about the value for money. Some find the size of the aquarium small and note they could go through it quickly—some in just 45 minutes. As one comment pointed out, “It’s very small but worth the experience,” emphasizing that despite its modest size, the exhibits are clean, well-maintained, and visually engaging.
Others criticize the lack of diversity in species or feel that the ticket price is high for what’s offered, citing a “quick and fast experience” with limited species compared to larger aquariums elsewhere. The augmented reality section was shut during some visits, which disappointed guests hoping for more interactive tech features.

Authentic Experiences and Visitor Feedback
Authentic reviews give a clearer picture. Many visitors enjoy the ease of entry—no long lines, especially with pre-booked tickets—and the convenient location. Families with children report the tide pools and touch tanks as favorites, and some appreciate the educational value of learning about local marine ecosystems.
However, a few reviews highlight frustrations—such as ticketing issues with third-party vendors, early closures, or overcrowding during peak times. One visitor shared they paid twice due to ticketing problems, which is worth noting if you plan to buy tickets online.
Practical Tips for Visitors
- Book early—especially if visiting during busy seasons—to avoid last-minute sold-out situations.
- Arrive early to beat the crowds and maximize your visit.
- Plan for about 2 hours to comfortably see all exhibits without rushing.
- If visiting with children or mobility concerns, note the elevators and stairs, and be prepared for some areas to be tight or crowded.
- Avoid relying solely on third-party vendors like Viator if you want a seamless experience, as some reviews reported acceptance issues.
Who Will Enjoy This Tour?

This aquarium is best suited for families with young children, who love hands-on activities like tide pools, and those interested in local marine ecosystems. It’s also ideal if you prefer independent exploration at your own pace, rather than guided tours.
While the size may disappoint serious aquarium enthusiasts or those expecting a vast array of species, the close-up views in the tunnels and the chance to learn about California’s marine life make it a worthwhile stop for many.
Final Thoughts: Is It Worth Visiting?

In terms of value, the $28 ticket offers a well-rounded look at the bay’s marine life, especially if you’re staying nearby or already planning to visit Pier 39. The interactive exhibits and walk-through tunnels are highlights that make the experience memorable. That said, if you’re seeking a large, diverse aquarium experience or are on a tight budget, you might find it limited.
For those who love learning about local ecosystems, enjoy self-guided visits, and want an easy, family-friendly outing, this aquarium fits the bill perfectly. Just be prepared for some reviews mentioning the size and variety, and plan accordingly.
