Aquarium of the Bay is located at Pier 39 on the Fisherman's Wharf waterfront, and unlike a sprawling institution, it's a focused, manageable aquarium centered on the marine ecosystem of San Francisco Bay and the nearby Pacific — the local sharks, rays, fish, and invertebrates, plus river otters and other animals.
The highlight is "Under the Bay," a pair of crystal-clear acrylic tunnels totaling around 300 feet that you walk through while sharks, bat rays, and large schools of fish glide overhead and on either side — an immersive, eye-level encounter that's especially thrilling for kids. Other exhibits include touch pools where you can gently feel rays and other creatures, a focus on local species and conservation, and smaller galleries of bay and ocean life.
Its size and location are the draw: you can see it thoroughly in about an hour, and it's right in the thick of Pier 39, steps from the barking sea lions, the shops, and the departure points for bay cruises and Alcatraz. That makes it an easy add-on to a waterfront day, particularly with younger children. For a larger, more comprehensive aquarium-and-science experience, the California Academy of Sciences in Golden Gate Park is the bigger option; Aquarium of the Bay wins on convenience and a quick, fun visit.
What to Expect
Format
Self-paced. Walk-through glass tunnels surrounded by sharks and rays, touch pools, and exhibits on San Francisco Bay marine life. Compact — about an hour.
Best Time
Any time; weekday mornings and later afternoons are calmer than midday weekends on the busy pier.
Duration
1-1.5 hours.
Tips
It's compact, so it's an easy add-on rather than a half-day. The walk-through tunnels are the highlight for kids. It's right at Pier 39, so combine it with the sea lions, a bay cruise, and the wharf. For a bigger aquarium experience, consider the California Academy of Sciences instead.

What's the main attraction?
The "Under the Bay" walk-through tunnels — clear acrylic tubes where sharks, rays, and schools of fish swim overhead and around you as you walk through. It's the aquarium's signature, immersive experience.
Is it good for young kids?
Yes — it's compact, kid-friendly, and quick (about an hour), with touch pools and the shark tunnels. It suits younger children and short attention spans well.
Where is it?
Right at the entrance to Pier 39 on the Fisherman's Wharf waterfront, steps from the sea lions and the cruise departure points.
How does it compare to the California Academy of Sciences?
Aquarium of the Bay is smaller and focused on local bay marine life, ideal for a quick waterfront stop. The California Academy of Sciences in Golden Gate Park is a much larger, all-in-one aquarium, planetarium, and natural history museum.
How long does a visit take?
About 1 to 1.5 hours — it's an easy add-on to a Fisherman's Wharf day rather than a half-day on its own.
