9 Illinois Zoos Families Should Have On Their Radar This Summer
Ever watched a child’s face light up at the sight of a giraffe, dolphin, penguin, or playful otter? That kind of summer magic is easy to find in Illinois.
Road trips, sunny afternoons, picnic stops, and animal encounters come together perfectly at the state’s many family-friendly wildlife destinations. Illinois offers huge, world-class attractions, peaceful park zoos, budget-friendly spots, and smaller gems made for relaxed exploring with kids.
Some places bring big-city excitement, while others feel like hidden local treasures tucked into quiet green spaces. Each one gives families a chance to learn, laugh, and make memories without needing an overly complicated trip.
Here are nine Illinois zoos and aquariums worth adding to your warm-weather adventure list.
1. Brookfield Zoo Chicago, Brookfield
Few zoos in the entire Midwest can match the sheer scale and excitement of Brookfield Zoo, located at 8501 West 31st Street in Brookfield, Illinois.
Spanning more than 200 acres, this place is an absolute powerhouse of wildlife experiences that keeps families busy from the moment they walk through the gates. With over 450 species of animals calling this zoo home, every path you take leads to something new and surprising.
One of the standout features here is the Tropic World exhibit, which is one of the largest indoor zoo exhibits in the world. You can watch gorillas, spider monkeys, and pygmy hippos moving through lush rainforest environments without ever stepping outside.
The Seven Seas dolphin shows are also a massive crowd-pleaser, especially for younger kids who cannot get enough of watching those playful animals perform.
Summer is genuinely one of the best times to visit because the zoo comes alive with special events, extended hours, and outdoor splash zones that help everyone cool down on hot days. The Australia House and the Hamill Family Play Zoo are also worth carving out extra time for.
Brookfield Zoo is accredited by the Association of Zoos and Aquariums, which means the animal care standards here are top-notch. Pack a picnic lunch, wear comfortable shoes, and plan to spend a full day because there is simply too much to squeeze into just a few hours.
2. Peoria Zoo, Peoria
Right in the heart of central Illinois, the Peoria Zoo at 2320 North Prospect Road in Peoria delivers a surprisingly rich animal experience that punches well above its size.
The zoo covers about 14 acres inside Glen Oak Park, giving it a comfortable, walkable layout that works perfectly for families with young children who need a manageable pace. Do not let the compact footprint fool you though, because the animal collection here is genuinely impressive.
The Africa exhibit is the crown jewel of Peoria Zoo, featuring giraffes, zebras, meerkats, and African wild dogs roaming through spaces designed to reflect their natural habitats.
Watching a giraffe stretch its long neck toward a feeding platform while kids giggle and point is one of those simple summer moments that sticks with you. The zoo also houses a Children’s Zoo area where little ones can interact with domesticated animals in a hands-on setting.
Peoria Zoo is operated by the Peoria Park District and places a strong emphasis on conservation education, so every visit feels meaningful beyond just seeing cool animals. Summer programming includes keeper talks, behind-the-scenes tours, and seasonal events that add extra layers of fun to your trip.
Admission prices are very reasonable compared to larger facilities, making this a budget-friendly option for families who want a quality experience without breaking the bank. Parking is free, which is a welcome bonus that larger city zoos rarely offer.
3. Phillips Park Zoo, Aurora
Aurora’s best-kept secret for family outings sits quietly inside the beautiful Phillips Park at 1000 Ray Moses Drive, and the fact that admission is completely free makes it one of the most lovable spots in all of Illinois.
Phillips Park Zoo has been welcoming families since 1915, making it one of the oldest small zoos in the state. That long history gives the place a warm, nostalgic character that feels refreshingly different from flashier modern attractions.
The zoo is home to a rotating collection of animals including bison, deer, exotic birds, reptiles, and small mammals that children can observe at close range.
The setting inside Phillips Park is genuinely gorgeous, with mature trees providing shade and a lagoon nearby that adds to the peaceful atmosphere. Because the zoo is small and relaxed, it is an ideal first zoo experience for toddlers and very young children who might feel overwhelmed by larger facilities.
Families often pair a zoo visit with a picnic on the park grounds, a ride on the miniature train, or a splash at the adjacent aquatic center during summer months.
The Aurora Park District manages the property with obvious care, keeping the grounds clean and the animal habitats well-maintained.
Local families return year after year, and it is easy to see why. A free, charming, historically rich zoo surrounded by one of Aurora’s most beautiful parks is a combination that is genuinely hard to beat on a warm Illinois afternoon.
4. Shedd Aquarium, Chicago
Technically an aquarium rather than a traditional zoo, Shedd Aquarium at 1200 South Lake Shore Drive in Chicago absolutely belongs on this list because no summer in Illinois is complete without a visit to one of the most celebrated aquariums in the entire world.
Opened in 1930 on the shores of Lake Michigan, Shedd has spent nearly a century perfecting the art of connecting people with aquatic life in ways that feel genuinely magical.
The newer Wonder of Water experience is an immediate showstopper, replacing the longtime Caribbean Reef centerpiece with a refreshed look at aquatic life and water conservation.
Watching a diver hand-feed a nurse shark while standing inches away from the glass is the kind of experience that children talk about for years afterward.
The Abbott Oceanarium is another unmissable highlight, where beluga whales and Pacific white-sided dolphins glide through massive pools in a theatrical setting with Lake Michigan as the backdrop.
Shedd also features jellyfish galleries, a freshwater exhibit celebrating the Great Lakes ecosystem, and a dedicated Wild Reef section that recreates a Philippine coral reef with stunning accuracy. Summer is peak season here, so booking tickets online in advance is strongly recommended to avoid long lines at the door.

This zoo has been part of the Bloomington community since 1891, making it one of the oldest continuously operating zoos in Illinois. That long institutional history shows in the thoughtful way exhibits have been developed and refined over the decades.
The star attraction at Miller Park Zoo is undoubtedly the snow leopard habitat, which has earned the zoo national recognition for its breeding program. Watching these rare, hauntingly beautiful cats pace through their rocky enclosure is a moment that genuinely stops visitors in their tracks.

Decatur’s Scovill Zoo at 71 South Country Club Road is a genuinely fun destination that combines a solid animal collection with a theme park-style energy that kids absolutely love.
The zoo sits inside the larger Scovill Park complex, which means your visit can naturally expand into other attractions without ever moving your car. That kind of built-in flexibility is something busy families deeply appreciate during summer outings.
The zoo houses hundreds of animals from around the world, which is an impressive draw for a mid-sized regional facility. Giraffes, ring-tailed lemurs, Aldabra tortoises, and a lively collection of primates are among the highlights that draw repeat visitors back season after season.
The giraffe feeding experience, where you can hand-feed these towering animals from an elevated platform, is consistently one of the most popular activities and is worth every penny of the small add-on fee.
Scovill Zoo also operates a miniature train that circles the zoo grounds, a carousel, and a splash pad area that provides sweet relief on hot summer afternoons.
The ZooAdventure Play Area gives kids a chance to burn off energy between animal viewings, which parents of active children will recognize as a genuinely thoughtful design choice.
