Buy a Zoo Pass and Explore More – Taking Advantage of the Reciprocal Zoo List

Zoo Pass and Platypus Circle members get free admission to the Milwaukee County Zoo and free or discounted admission to more than 150 other zoos and aquariums! We reciprocate this offer with fellow members of the Association of Zoos & Aquariums that choose to be part of this program. There are some zoos that choose not to be part of the reciprocal program and are not included on this list such as Brookfield Zoo (Chicago), San Diego Zoo, San Diego Wild Animal Park, and all Sea World locations. If a zoo or aquarium is not on our list, there is no reciprocation with free or discounted admission. We do not reciprocate with zoos in close proximity to the Milwaukee County Zoo, including the Henry Vilas Zoo in Madison, Lincoln Park Zoo in Chicago, NEW Zoo & Adventure Park in Suamico and Racine Zoological Gardens. This list is updated each year.

What does my Zoo Pass cover at a reciprocal zoo?

Reciprocal zoos offer free or discounted admission to Zoo Pass holders. Most institutions limit reciprocity to two adults and two children and do not offer reciprocity for parking or special events. Some free zoos offer reciprocal discounts on attractions and/or gift shop purchases.

What do I need to do to prepare for a reciprocal zoo visit?

Check with the zoo or aquarium you plan to visit for reciprocity details and to make sure there isn’t a special event happening the day you plan to visit. Important Note: Zoo databases are not linked. Other zoos will not be able to verify your membership, so please be prepared and always have your Zoo Pass along with your picture I.D. ready for the attendant. If you visit a reciprocating institution but are asked to pay, please keep your receipt. Once you return, contact our office at 414-258-2333 immediately for assistance. Unfortunately, we cannot guarantee that you will be reimbursed, but we will make an attempt on your behalf.
