Planning a visit to the Aquarium of the Bay? Located at PIER 39 in San Francisco’s Fisherman’s Wharf district, this family-friendly attraction offers an immersive look at the animals and habitats found in San Francisco Bay and the surrounding Northern California watershed. Its walk-through underwater tunnels, touch pools, sharks, rays, jellyfish, and playful river otters make it an appealing stop for families, couples, and anyone curious about local marine life.
What Is Aquarium of the Bay?
Aquarium of the Bay is a Smithsonian-affiliated nonprofit aquarium whose mission centers on protecting, restoring, and inspiring conservation of San Francisco Bay and its watershed. Rather than presenting marine life from every corner of the world, the aquarium introduces visitors to animals and environmental issues closely connected to Northern California.
The attraction is located at the entrance to PIER 39, at The Embarcadero and Beach Street. Its waterfront setting is part of the experience: visitors can explore the marine ecosystem inside and then step outdoors to see the Bay, Alcatraz Island, passing boats, and the famous PIER 39 sea lions.
The aquarium reports that its habitats contain more than 24,000 animals representing over 200 species. Exact animal populations can change, but visitors may encounter sharks, rays, skates, anchovies, rockfish, jellyfish, octopuses, tide-pool animals, and North American river otters.

Walk Through the Under the Bay Tunnels
The signature Aquarium of the Bay experience is Under the Bay, an exhibit area featuring two transparent tunnels totaling approximately 300 feet. The tunnels pass through habitats containing more than 750,000 gallons of carefully maintained San Francisco Bay water.
As fish swim above and around the passageway, visitors can observe the shapes, movements, and behaviors that are difficult to appreciate from the shoreline. Depending on the habitat and the animals present during your visit, you may see leopard sharks, soupfin sharks, broadnose sevengill sharks, bat rays, skates, rockfish, and schools of anchovies.
The tunnels are dramatic without relying on amusement-park effects. Their appeal comes from the feeling of entering a living Bay environment and watching local species from below. Children often enjoy spotting animals overhead, while adults and photographers may want to move more slowly and observe how the inhabitants interact.
Explore Touch the Bay
Touch the Bay turns observation into a supervised, hands-on learning experience. Its touch pools may allow visitors to gently encounter animals such as bat rays, skates, juvenile sharks, sea stars, and sea cucumbers. Animal availability and handling instructions can vary, so guests should always follow the guidance provided by aquarium staff.
This area is particularly engaging for children, although curious adults are equally welcome. Interpretive naturalists can explain how the animals move, feed, protect themselves, and fit into the broader ecosystem. The experience helps transform an aquarium visit from passive sightseeing into a memorable environmental lesson.
Meet the River Otters
North American river otters are among the aquarium’s most charismatic residents. The River Otters: Watershed Ambassadors exhibit connects their behavior and habitat to the health of rivers, wetlands, and the wider Bay watershed.
Otter activity naturally varies throughout the day. Presentations, feedings, or training sessions may provide especially good opportunities to see them moving through the water and interacting with their environment. Check the day’s program after arriving rather than assuming a particular activity will occur at a fixed time.
Discover Jellyfish, Octopuses, and Bay Habitats
Beyond the headline attractions, Aquarium of the Bay features habitats that reveal the surprising variety of local aquatic life. Moon jellies and sea nettles create an almost meditative display, while octopuses demonstrate remarkable camouflage and problem-solving behavior. Colorful rockfish, bright-orange garibaldi, moray eels, and coordinated schools of anchovies show that the waters around San Francisco are far more diverse than they may appear from the surface.
How Long Should You Spend at Aquarium of the Bay?
The aquarium advises that an average visit takes approximately 90 minutes. Presentations can add another 10 to 20 minutes, and visitors who enjoy reading every display or observing animal behavior may stay longer.
Allowing about two hours provides a comfortable pace for most travelers. That leaves time to revisit a favorite habitat, ask the naturalists questions, and avoid rushing through the underwater tunnels. Families with young children may prefer a shorter visit, while marine-life enthusiasts could easily spend additional time inside.
Because the attraction is relatively compact and centrally located at PIER 39, it fits well into either a half-day Fisherman’s Wharf plan or a longer waterfront sightseeing day.
Aquarium of the Bay Tickets, Hours, and Practical Tips
At the time of writing, Aquarium of the Bay lists standard daily hours of 10:00 a.m. to 5:00 p.m., with last entry generally at 4:30 p.m. Holiday hours, temporary closures, ticket prices, and special programs can change. Confirm the latest information on the official Aquarium of the Bay visitor page before leaving your hotel.
Advance online tickets can simplify arrival during weekends, school breaks, and busy travel periods. The aquarium offers adult, child, and senior admission categories, while children aged three and younger are generally admitted free. Eligible visitors may also find local-resident, military, group, Museums for All, or public-transit discounts. Restrictions apply, and discounts may not be combined.
Keep these practical tips in mind:
- Arrive near opening time if you prefer a quieter atmosphere.
- Review the daily presentation schedule when you enter.
- Dress in layers, since the waterfront can feel cool and windy even when downtown is mild.
- Allow extra time for PIER 39, especially when traveling with children.
- Use public transportation when practical, as waterfront parking can be expensive.
- Ask aquarium staff before touching or photographing animals in sensitive areas.
What Else Can You Do Near the Aquarium?
Aquarium of the Bay sits in one of San Francisco’s most attraction-rich areas. After the aquarium, visitors can watch the California sea lions at PIER 39, browse waterfront shops, or stop for a meal overlooking the Bay. Boat cruises also depart from the surrounding waterfront, including excursions offering views of the Golden Gate Bridge and Alcatraz Island.
A short walk west leads deeper into Fisherman’s Wharf, where travelers will find maritime attractions, seafood restaurants, and views across the water. Continue toward Hyde Street for historic ships and additional waterfront scenery. To the east, walking along The Embarcadero eventually leads toward the Ferry Building, although covering the full route requires additional time.
North Beach and Chinatown can also be paired with an aquarium visit. North Beach is known for Italian dining, cafés, and literary history, while Chinatown offers traditional markets, bakeries, restaurants, and historic streets.
Aquarium of the Bay vs. Other San Francisco Science Attractions
Aquarium of the Bay is best suited to travelers who want a focused marine-life experience in a convenient waterfront location. Its manageable size makes it easier to combine with other attractions than a large, full-day museum.
The California Academy of Sciences in Golden Gate Park offers a much broader experience encompassing an aquarium, planetarium, rainforest, and natural-history exhibits. It generally requires more travel time from downtown and rewards a longer visit. The Exploratorium, located on the Embarcadero at Pier 15, emphasizes interactive science, perception, and experimentation rather than concentrating on marine animals.
None is universally better; the right choice depends on your schedule. Choose Aquarium of the Bay for local aquatic life and a PIER 39 itinerary, the California Academy of Sciences for an expansive natural-science day, or the Exploratorium for hands-on scientific discovery.
Why Stay at Cornell Hotel for Your San Francisco Aquarium Trip?
Cornell Hotel offers a different experience from the large waterfront properties surrounding Fisherman’s Wharf. Originally built in 1910, the boutique hotel combines French-inspired character with individually decorated. Its corridors feature prints associated with artists such as Matisse, Chagall, Gauguin, Modigliani, and Toulouse-Lautrec, giving the property a distinctive identity.

Cornell Hotel is located at 715 Bush Street in the Nob Hill and Union Square area. Although it is not a Fisherman’s Wharf hotel, its central setting gives guests several ways to reach PIER 39 while remaining close to downtown dining, shopping, theaters, Chinatown, and the Financial District.
Public transit is usually the most practical choice. Depending on current service, guests can connect with Muni routes serving The Embarcadero and Fisherman’s Wharf. The historic F-line streetcar stops near PIER 39 at The Embarcadero and Beach Street. Cable cars can also turn the journey toward the waterfront into part of the sightseeing experience, although lines and service conditions vary.
