Here’s a little-known trick that families who visit zoos and aquariums regularly have figured out: one membership at your home zoo can get your family free or deeply discounted admission at more than 230 other zoos and aquariums across North America. It’s called the AZA Reciprocal Admissions Program, and it’s one of the best values in family entertainment if you know how to use it.

What Is the AZA Reciprocal Admissions Program?

The Association of Zoos and Aquariums (AZA) is the accrediting body for the highest-quality zoos, aquariums, and wildlife parks in North America. AZA accreditation is rigorous — institutions must meet strict standards for animal care, conservation, education, and safety. There are about 240 AZA-accredited facilities total.

The Reciprocal Admissions Program is a benefit many AZA-accredited institutions offer to their members: if you hold a qualifying membership at a participating institution, you get free or discounted admission at other participating AZA institutions when you visit. The current program list covers May 2026 through April 2027.

How It Works

The core concept is simple:

1. Purchase a qualifying membership at an AZA-accredited institution near your home
2. When traveling, check the AZA Reciprocal Admissions list at aza.org for participating institutions
3. Show your membership card at the guest services desk of the institution you’re visiting
4. Receive free or discounted admission

Reciprocal benefits typically fall into two tiers: free admission (the best case — you simply walk in) or discounted admission, usually 50% off the general admission price. Which benefit you receive at a given institution depends on the agreement between that institution and yours.

How to Pick the Right Home Institution

Not every AZA member institution participates in reciprocal admissions, and the institutions that do offer different levels of benefit to incoming members. Before buying a membership, do a little research:

• Look at the AZA’s current reciprocal admissions list and see which institutions your target membership would give you access to. You can typically find this list on the membership page of your home institution’s website, or at aza.org.
• Check institutions you’re likely to visit — if you travel to a city with a major zoo or aquarium every year, make sure your home membership gives you reciprocal access there.
• Compare membership tiers — some institutions offer a basic membership that doesn’t include reciprocal benefits, but a slightly higher tier does. The price difference is often worth it if you travel at all.
• Look for memberships that offer “Plus” or “Premier” AZA reciprocal access — some home institutions send members to the full reciprocal program, while others participate in a more limited version.

Important Rules and Caveats

The reciprocal program comes with some rules that can trip you up if you don’t know them in advance:

Geographic Neighbors May Be Excluded

The most important rule: the institution you’re visiting may exclude your home institution from its reciprocal benefits if they’re considered geographic competitors — meaning they’re in the same city or metro area. For example, if you live in Chicago and hold a Lincoln Park Zoo membership, the Shedd Aquarium (also in Chicago) may not honor that membership for reciprocal benefits. Always call ahead when visiting any institution within 90 minutes of your home.

Special Exhibits Are Often Excluded

Reciprocal benefits typically cover general admission only — not ticketed special exhibits, IMAX shows, rides, or behind-the-scenes experiences that require a separate ticket. Some institutions exclude seasonal events and holiday light shows as well. When in doubt, check the institution’s website before arriving.

Always Call Ahead

Reciprocal lists are updated annually (the current list covers May 2026 through April 2027), but participation can change, and some institutions may temporarily suspend reciprocal benefits during peak periods or major events. Before a trip, call or email the institution you’re planning to visit to confirm: (1) they’re currently participating in reciprocal admissions, (2) they honor your home institution’s membership, and (3) there are no exclusion dates during your visit.

Bring Your Membership Card and Photo ID

You’ll need to show your physical membership card or app, along with a photo ID matching the primary member name. Digital cards work at most institutions — check your membership provider’s app before traveling. Some institutions may require you to show the original purchase receipt for digital-only memberships, so keep that in your email.

Not All AZA Institutions Participate

AZA accreditation is separate from program participation. An institution can be AZA-accredited without participating in the reciprocal admissions program. Always verify against the current list at aza.org rather than assuming any AZA institution participates.

The Math: Is It Worth It?

Let’s say a family zoo membership near your home runs $120–$160 per year. Average zoo general admission for a family of four runs $80–$140 at many major institutions. If you visit your home zoo twice (already covering the membership cost) and use reciprocal benefits at one other zoo during a vacation, you’ve saved the cost of 2–3 separate admissions — often $100–$200 in total savings. If you’re a family that travels and enjoys these kinds of attractions, the math gets very favorable very quickly.

Also Worth Knowing: Museums for All

If your family receives SNAP/EBT benefits, many AZA-accredited zoos and aquariums also participate in the Museums for All program, offering $1–$5 admission per person (up to 4 people) when you show your EBT card and photo ID. This is separate from the AZA reciprocal program and doesn’t require a membership. Check museums4all.org for participating institutions near you.

The AZA Reciprocal Admissions Program is genuinely one of those membership benefits that rewards families who plan ahead and do their research. Pick the right home institution, check the list before every trip, and call ahead — and you can visit world-class zoos and aquariums across the country for the price of a single annual membership.

If your family enjoys educational travel, also see our guides on the ASTC Passport Program (reciprocal access to 300+ science centers and discovery museums) and the America the Beautiful Pass (national parks, forests, and federal lands). Together, these three programs cover a remarkable amount of family travel for relatively little upfront cost.
