Aquarium of the Bay

Aquarium of the Bay at Pier 39 delivers one of the most viscerally exciting experiences you can offer a young child at Fisherman's Wharf: walking through a 300-foot transparent underwater tunnel with 7-foot sharks gliding silently overhead. For most kids, this is a full-body awe moment that outdoor attractions struggle to replicate.

The aquarium focuses specifically on San Francisco Bay and Pacific Coast marine life, which gives it an educational coherence that makes every exhibit feel relevant to where you're standing. You're looking at the actual creatures that live in the actual bay that's 50 feet outside — bat rays, leopard sharks, salmon, sturgeon, jellyfish, and species that are genuinely local.

The touch pools are consistently the most memorable hands-on experience for kids. Bat rays have a texture that surprises everyone who touches them — they feel like smooth velvet, not what people expect from something that looks like it should be rough and slippery. Children who touch a bat ray for the first time often want to do nothing else for the next 20 minutes.

Staff are present to guide interactions safely.

At 4.1 stars across over 6,000 reviews, the aquarium's rating reflects its relatively compact size compared to major facilities like the Monterey Bay Aquarium. Manage expectations on scale — this is a 1-2 hour experience, not a half-day destination. The price point reflects the location at Pier 39.

For maximum value, book tickets online (discounted vs. walk-up), combine with the free sea lion colony at the end of Pier 39, grab clam chowder in a sourdough bowl, and treat the whole thing as a Fisherman's Wharf half-day package. That's the optimal SF tourist family experience centered on this location.
