The St. Louis Zoo is one of the crown jewels of Forest Park, pairing world-class exhibits with unforgettable animal encounters – all for the unbeatable price of FREE. Wander through River’s Edge among elephants, hippos and rhinos, cool off with the tuxedoed residents of Penguin & Puffin Coast, and catch impressive water acrobatics at Polar Bear Point and Sea Lion Sound. Over at Red Rocks, giraffes stretch above the crowd while big cats lounge or prowl, and the Primate House delivers plenty of entertaining monkey business. Whether you’re an animal lover or simply looking for one of the best things to do in St. Louis, the Zoo is a must-see.
📚 Backstory: From Flight Cage to World-Class Zoo
- 🦅 The Zoo’s roots trace back to the 1904 World’s Fair, when the Smithsonian Institution commissioned the massive Flight Cage that still stands in the Zoo today.
- 🦁 The popularity of the Flight Cage helped inspire St. Louis to establish a permanent zoological park, with the Zoological Society of St. Louis founded in 1910.
- 🏛️ Many of the Zoo’s historic buildings followed in the 1920s and 1930s, including the Herpetarium, Primate House and Bird House, giving Historic Hill its distinctive architecture.
- 🌳 Today, the St. Louis Zoo spans about 90 acres in Forest Park and is home to thousands of animals representing hundreds of species.
- 🎟️ Thanks to public support through the Metropolitan Zoological Park and Museum District, general admission remains free, helping make the Zoo one of St. Louis’ most accessible attractions.
📍 Location: Where the Wild Things Are
- 🌳 Forest Park – The St. Louis Zoo sits within Forest Park, alongside some of the city’s other major attractions, including the St. Louis Art Museum, The Muny and Missouri History Museum.

💡 Tips: Keep Your Herd Happy
- ⏰ Arrive Early – Beat the stampede for parking and prime viewing. Animals are often more active during the cooler morning hours, and you’ll beat some of the crowds and summer heat.
- 🚗 Park for Free – Skip the paid Zoo lots (~$20) at each entrance and look for free street parking in Forest Park. We’ve typically found more free parking availability near the South Entrance.
- 🗺️ Plan your journey to see the most animals – Use this helpful interactive zoo map.
- 🍎 Bring Snacks & Water – Although there are plenty of eateries, bringing your own grub can save you some bucks. You are allowed to bring picnic baskets, coolers, food and drinks – except glass bottles and alcohol.
- 🐾 Expect the Unexpected – Every Zoo visit is different. Animals may be running around one day and sound asleep the next, so don’t be afraid to circle back to a favorite habitat.
- 🐣 Visit When There Are Babies – New arrivals are some of our favorite reasons to return. Young animals tend to be especially playful and can make an ordinary Zoo visit unforgettable.
- ☀️ Plan Around the Heat – On hot summer days, mix outdoor exhibits with cooler indoor stops like the Penguin & Puffin Coast, Primate House, Herpetarium and Bird House.
- 👟 Wear Comfortable Shoes – The Zoo covers a lot of ground, and you’ll do plenty of walking if you want to explore all six zones.
🐾 Visits: Pawsitively Unforgettable Experiences
We’ve visited the zoo countless times, and each visit is a new adventure – you never know which animals will be goofing around, peacefully napping, or splashing up a storm.
🎥 St. Louis Zoo: Animal encounters with Elephants, Sloths, Monkeys, Ocelot & More
🐘 River’s Edge: Roaming with Giants
River’s Edge is my favorite area – a place where you truly feel like you’re walking among free-roaming giants. Stroll through lush, jungle-inspired pathways and admire the majestic elephants, happy hippos, and powerful rhinos as they roam, splash, and graze in expansive habitats. Keep an eye out for the spotted hyenas and sleek cheetahs nestled in the bamboo, and don’t miss the chance to peek at the cobra’s eggs – a fascinating surprise for the kiddos.
🐘 Elephants
🦏 Hippos & Rhinos
🐆 Cheetahs & Hyenas
🦒 Red Rocks: Big Cats, Long Necks & Little Stripes
Head over to Red Rocks to feed giraffes (for a small fee), watch big cats strut with confidence, marvel at zebra stripes, admire antelope horns, and count camel humps. We even spotted Zuko, the Zoo’s first ocelot in 57 years, doing what cats do best – snoozing inside a tire. We’ve been lucky to see some adorable Zoo babies here over the years, from playful baby tigers tumbling around with their ball and barrel toys to Prince, a baby Grevy’s zebra, happily munching grass. If there are new arrivals at the Zoo, it’s always worth another visit – seeing the little ones grow, play and explore makes every trip a little different.
🦍 Primates: Monkey Business
Head up to Historic Hill to see the endlessly entertaining primates, with each visit offering a new and playful adventure as they swing, climb, and interact with guests or each other. For playful monkeys and lemurs, swing over to the indoor Primate House or outdoor Primate Canopy Trails expansion. To catch a glimpse of the mighty gorillas, energetic chimpanzees, and curious orangutans, head to the The Wild’s outdoor Fragile Forest or indoor Jungle of the Apes. Don’t miss getting a picture with Phil the Gorilla statue.
🦥 Sloth Atrium: Hanging Around
The new Sloth Atrium was one of the highlights of our August 2026 visit. We got to see Rolo and Pancakes, with one surprisingly active in a tree beneath a light while the other was completely zonked out inside a red-lit hollow tree. Their opposite energy levels made for a pretty perfect sloth encounter, and the intimate habitat inside the Primate House lets you get surprisingly close.
🦭 Sea Lion Sound: Making a Splash
The sea lions never fail to put on a show – whether they’re performing graceful water acrobatics as they flip and dive above you in the underwater tunnel, or dazzling crowds during their official show. Located in Lakeside Crossing, Sea Lion Sound is a must-see experience that brings you up close with these playful marine performers.
🐧 Penguin & Puffin Coast: Chill with Tuxedoed Cuties
Penguin & Puffin Coast in The Wild is the perfect escape from the St. Louis summer heat, where playful, tuxedoed cuties splash and waddle around in their icy habitat. It’s a cool retreat that’s just as fun to visit as it is refreshing.
🐻❄️ Polar Bear Point: Pawsitively Cool
Polar Bear Point in The Wild is another must-see, where you can watch these powerful predators glide effortlessly through the water, showcasing their strength and grace up close.
🐻 Grizzly Ridge: Get Your Bear-ings
Also in The Wild is Grizzly Ridge, where you can admire these powerful giants up close as they roam and explore their rugged habitat.
🚂 Zooline Railroad: Choo-Choose to Ride

🦈 Zoo Landmarks: From the World’s Fair to The Living World
The zoo is home to a collection of fascinating buildings that showcase wildlife from around the world. At the North Entrance, you’ll find the Living World, a dynamic visitor center featuring exhibits, classrooms, and a café. One of the zoo’s most historic structures is the 1904 Flight Cage, originally built for the World’s Fair and now part of the Cypress Swamp exhibit, where native birds and lush greenery create a serene, immersive experience. To see more feathered friends, fly over to the Bird House and Garden. Reptile enthusiasts can explore the Herpetarium, where snakes, lizards, and amphibians thrive in carefully crafted environments. For a closer look at nature’s tiniest architects, step into the Insectarium, where you can marvel at colorful butterflies, busy ants, and other incredible insects. Each of these unique spaces adds to the rich tapestry of discovery and learning.
🎄 Seasonal Events: A Wild Time Year-Round
The zoo is not only a fantastic destination for animal encounters but also a hub for spectacular seasonal events. During the holidays, the zoo comes alive with Wild Lights, where twinkling displays transform the grounds into a winter wonderland, and Animals Aglow, a mesmerizing lantern festival that illuminates the pathways with larger-than-life animal sculptures. In the fall, families flock to Boo at the Zoo, a kid-friendly Halloween celebration filled with costumes and spooky fun, as well as Zootoberfest, where you can enjoy German-inspired food, live music, and local brews.
