The Ty Warner Sea Center is the aquatic branch of the Santa Barbara Natural History Museum, and is located right over the Pacific Ocean on Stearns Wharf. It is a small aquarium, but what it lacks in size, it makes up with engaging and accessible exhibits.
At the shark touch-pool, my son got to touch a harmless swell shark. The tidepool tank had viewing windows that were accessible to even the youngest toddlers and an underwater tunnel for them to walk through as well.
Older kids enjoyed some of the computer-based exhibits throughout the first floor of the center. We also spent some time with some other aquarium youth volunteers as they pulled up samples (of mostly seaweed) in netted cages attached to ropes. They were all great about answering questions and giving information about specimens they had for viewing under video microscopes.
The second floor of the aquarium was a special exhibit called Superpowers, about animal adaptations, which included another touch-pool opportunity. The 39-foot model of the gray whale and her calf hangs in the main entrance, right over the gift shop.
Useful Tidbits: Admission for just the Sea Center is currently $8 for adults and $5 for children ages 2-12. You can also get a Santa Barbara Nature Pass and get admission for the Sea Center and Natural History Museum for two days. Parking is free for the first 90 minutes with validation from the Sea Center. Check the website for current information.
