Annual Passes
There’s always something new to see and do at the Aquarium, so the best value for admission is an Annual Pass.
An Annual Pass lets you visit the Aquarium as often as you like throughout the year. And you won't need to get timed tickets for admission - just come any time we are open!
When you buy your annual passes online, you will bring the email confirmation to the Aquarium on your first visit, get your picture taken and pick up your passes.
Each pass purchased is associated with the specific person whose name and photo will be on the pass. Passes can be used by the individual passholders at any time. Even if they are purchased in a group, they do not have to be used in a group.
Buying the pass as a gift? Your recipient can bring the confirmation to the Aquarium and have the pass created in their name.
Children 2 and under do not require annual passes.
