Reciprocating Zoos & Aquariums

One of the great benefits of being a FONZ member is free or discounted admission to other reciprocating zoos and aquariums, and in some cases, discounts in their shops.

The zoos and aquariums listed below offer free or discounted entrance admission to current FONZ members. When visiting these institutions, please present your current FONZ membership card and an ID. If you have any questions, please contact the FONZ Membership Office at (202) 633-3042.
