If you are under age 2 they let you in free, but otherwise everyone is the same rate and we paid well over $20 for a 3-year-old and two adults. That bothered me, especially after I realized how small the aquarium was (two rooms with several exhibits "in progress" - in other words, nothing there yet). (There is also a gift shop.) Our small guest didn't want to touch any of the sea creatures, so although it's a very nice feature to have staff offering to let you touch sea stars, urchins, and other small ocean animals, this didn't turn out to suit our guest. You can learn a lot about the animals from the docents, but if you have a little one with you, they hardly want to stand still while Auntie gets information about sea star legs.
At age three they don't gaze too long at any one creature in a tank, so crabs, lobsters, small sharks, big fish, and even jellyfish didn't hold his attention for long. The little one didn't want to listen to or stand still for a docent's talk about small sharks, either. This made for an awfully quick and expensive visit to this aquarium.
It's nice that the docents give talks about the creatures (like the small sharks that they let visitors touch under supervision) and that a schedule is posted about activities such as jellyfish feeding. Once you pay you can come and go if you keep your receipt, so visitors can return for activities they're interested in. This just doesn't work for little kids who get exhausted during an Avila Beach visit and are taken home, so I'd only recommend this aquarium for older kids and for adults who are interested in a hands-on experience with sea life. In my opinion we need something different for the little kids.
