Brookfield Zoo Free Days You Shouldn’t Miss

Introduction

Brookfield Zoo, located just outside Chicago in Brookfield, Illinois, is one of the best family-friendly attractions in the Midwest. Known for its diverse collection of animals, beautifully designed exhibits, and commitment to conservation, it’s a favorite for both locals and tourists. But what many people don’t realize is that you can enjoy everything this world-class zoo has to offer without spending a dime on admission, thanks to Brookfield Zoo free days.

Whether you’re planning a budget-friendly outing, introducing your kids to wildlife, or just looking for a fun way to spend the day, this guide will walk you through everything you need to know about visiting Brookfield Zoo on a free day.

What Are Brookfield Zoo Free Days?

Brookfield Zoo free days are select dates throughout the year, usually in the off-season months, when Illinois residents receive free general admission to the zoo. These days are offered as a way to make the zoo accessible to more people and encourage visits during less busy times of the year.

The zoo typically offers multiple free days in January and February, as well as other select dates like Martin Luther King Jr. Day. On these days, admission fees are waived for all qualifying visitors who bring proof of Illinois residency, such as a state ID or utility bill.

2025 Free Admission Dates (Expected)

While the zoo announces official dates each year, based on previous schedules, we can expect the following:

• Every Tuesday and Thursday in January and February 2025
• Martin Luther King Jr. Day on January 20, 2025
• Potential additional dates announced seasonally

Keep in mind, these free days usually apply to general admission only. Parking, attractions like the Dolphin Show or Butterflies!, and special events may still require a ticket.

Why You Should Take Advantage of Brookfield Zoo Free Days

There are many reasons why visiting on a free day is worth it. First, of course, is the savings. Regular adult admission to Brookfield Zoo can cost over $25, and children’s tickets cost around $20. If you’re visiting with your family, those numbers add up quickly. Free days make it possible to enjoy the experience without financial strain.

Another major benefit is the reduced crowds, especially during winter free days. Cooler temperatures often mean fewer people, giving you a more peaceful, spacious visit. Plus, many of the animals, especially those from colder climates like bears, wolves, and big cats, are more active in cool weather.

Top Exhibits to Explore During Your Visi

Even without paying for extras, Brookfield Zoo offers an incredible variety of exhibits included in your free admission. Be sure to check out:

Tropic World – A massive indoor rainforest exhibit home to monkeys, apes, and exotic birds from South America, Africa, and Asia. This is a warm indoor stop that’s perfect for cold days.

Great Bear Wilderness – This exhibit showcases polar bears, bison, bald eagles, and more in large naturalistic habitats.

Big Cats – Lions, tigers, leopards, and snow leopards are all here. Cooler months are great for seeing them up and moving.

The Living Coast – A vibrant aquatic exhibit featuring penguins, sharks, and stingrays. It’s another great indoor space to enjoy during winter visits.

Tips for Making the Most of Your Brookfield Zoo Free Day

Check the Schedule: Confirm the free admission dates by visiting the official Brookfield Zoo website before your trip. Dates can change or sell out if pre-registration is required.

Bring Proof of Illinois Residency: An Illinois driver’s license, state ID, or a utility bill with your address is required for free entry.

Arrive Early: Free days tend to be popular, even during winter. Arriving when the zoo opens gives you more time to explore and helps you avoid long entry lines.

Dress Appropriately: Many exhibits are outdoors. Bundle up during winter visits, and wear comfortable walking shoes.

Pack Your Own Food: While there are places to eat inside the zoo, they can be pricey. Bringing your own lunch and snacks is allowed and can help you save even more.

Download the Zoo Map: This helps plan your route and avoid backtracking, especially on colder days when you want to stay indoors longer.

Parking and Additional Costs

Parking at Brookfield Zoo is not free, even on free admission days. The standard parking fee is around $15 per car. If you’re trying to save, consider carpooling or taking public transportation. The Metra BNSF line has a stop near the zoo at Hollywood Station, which is within walking distance of the north gate.

Also note that while general admission is free, there are a few exhibits and attractions that still charge separate fees. These include:

• Dolphin presentations
• Hamill Family Play Zoo
• Butterfly exhibit (seasonal)
• Carousel rides

If you’re bringing kids, it might be worth budgeting a small amount for one or two paid attractions.

Who Else Gets Discounts or Free Admission?

In addition to free days, Brookfield Zoo offers year-round discounts to certain groups:

• Military personnel (active, reserve, and retired) receive free general admission with ID
• Seniors over 65 receive discounted admission
• Visitors with EBT or LINK cards qualify for $3 admission through the Museums for All program
• Public library pass programs in Chicago and the suburbs offer free admission passes on rotation

Check with your local library to see if they participate.

A Year-Round Favorite, Now More Accessible

Brookfield Zoo free days are not only a chance to save money—they’re also a fantastic reminder that education and exploration can be available to everyone, regardless of budget.

Whether you’re visiting with your family, taking a solo trip, or exploring with friends, a free day at the zoo is a rewarding and refreshing way to spend time outdoors and see some of the world’s most fascinating animals up close.
