What You’ll Experience at Green Cay Wetlands Nature Center and Boardwalk
Green Cay Wetlands and Nature Center is an experience that blends outdoor recreation with education and conservation. Built on what was once farmland, the wetlands were constructed to filter stormwater and mimic the natural flow of the Everglades ecosystem. Today, they attract thousands of visitors each year who come for both the scenery and the wildlife encounters. Green Cay is definitely one of the best free things to do in South Florida.
The journey begins with a small butterfly garden near the entrance that’s buzzing with color. Upon entering, you’ll find yourself at the entrance of the Nature Center. Inside is full of aquariums, interactive displays, and exhibits that set the stage for what you’ll see outside. From there, the boardwalk trail loops through open marshes, cypress swamps, and tree islands. Along the way, you’ll encounter dozens of native and migratory species, sometimes so close you’ll be able to see the details of their feather or scales.
Green Cay Wetlands Interactive Nature Center
The Nature Center is open Wednesday through Saturday from 9 AM to 3 PM, except on county holidays. The Center has different exhibits outlining the wetland’s story, and unique features like a turtle pond and a mini alligator hole, with real live baby gators! It’s great for kids and adults, turning a visit into a mix of adventure and education. If you want to see what it looks like, you can take a virtual tour before you arrive. They have public restrooms available from 6:45 AM to sunset.
Inside, you’ll find frogs and snakes in tanks, turtles swimming and Oliver, a rescued screech owl being cared for. In the back, there is a display that breaks down how wetlands clean water, with models showing the flow from marshes to the aquifer. It’s pretty cool to see how nature does the heavy lifting! There’s also a kid friendly zone with hands on activities, like feeling different animal hides or matching bird calls to species.
They have a small gift shop with shirts, hats, magnets and other small souvenirs for those who want a memento. Friendly staff is around to answer questions, often pointing out what animals are active outside that day. It’s a great spot to start your visit, especially if you want to understand what makes Green Cay Wetlands so special before hitting the boardwalk.
Green Cay Wetlands Boardwalk
Open everyday from sunrise to sunset, the 1.5 mile elevated boardwalk winds through 100 acres of carefully designed wetlands. The trails are accessible for wheelchairs and strollers, and benches are placed along the boardwalk, providing spots to relax and take in the scenery and animals. Scattered throughout are gazebos and huts, which offer some relief from the Florida sun.
There are different routes you can take, so you can decide how much you want to (or don’t want to) walk. As you make your way along, you’ll see signs and QR codes that share cool facts about the plants and animals around you (like how a wood stork hunts for fish or why the marsh is so good at cleaning water). There is a bird watching checklist for anyone interested in keeping track of the birds they see too.
Green Cay Wetlands Lush Wildlife
South Florida wildlife is everywhere you turn at Green Cay Wetlands. Between the flora and the fauna, you’ll see something wild no matter where you turn. Monarch, swallowtail, and zebra longwing butterflies gather in the entrance’s butterfly garden, starting your visit off with vibrant colors. Over 250 bird species have been seen at Green Cay, including great blue herons, anhingas, snowy egrets, white ibis, and roseate spoonbills (you can’t miss them with their bright pink feathers). January and February bring flocks of wood storks, who make nests in the trees. They are loud and plentiful during this time of year. It’s a truly unique sight; with all the babies, it’s great for birdwatching!
Of course, the most anticipated animal people hope to see in Florida is the alligator. There are plenty who live in the waters of Green Cay! There’s a very likely chance you’ll see one during your visit. Just be sure to keep your eyes open. They like to rest in shady areas along the marsh edges and in shallow waters. But, sometimes you’ll catch them moving through the swamps, with just their spiky tails poking out of the water!
Florida softshell turtles, peninsula cooters, and sliders love to lounge on logs. One place you can usually find them is right past the wooded area in Zone 7. Occasionally, river otters are seen swimming, and even bobcats sometimes appear in the brush. Green Cay’s wildlife highlights its importance as a protected habitat, offering visitors a chance to see Florida’s native animals in their natural environment.
Spotting Iguanas at Green Cay Wetlands
Iguanas are all over the place at Green Cay, but not always in plain view. They love fruit trees, so if you look through the branches, you may catch one. Another place they tend to spend time is on the grassy areas along the boardwalk. But, our favorite spot, and almost 100% guaranteed to spot one of these guys is in the marshes in Zone 6. The older, larger iguanas find the shady areas to stay cool, while the smaller ones love to bask in the sun’s heat.
Some Iguanas are Harder to See
Iguanas are actually not native to Florida. They are invasive, and quite destructive in residential neighborhoods and to the overall Florida ecosystem. To learn more how they got here, and why they’re taking over South Florida, we discuss it here!
If iguanas are invasive and disrupt the ecosystem, why are they at Green Cay Wetlands?
Iguanas are tolerated at Green Cay Wetlands because the controlled environment, overseen by Palm Beach County Parks and Recreation, limits their disruptive impact. The wetland’s design and staff monitoring help prevent iguanas from overpopulating or significantly harming native plants and animals. Unlike in residential communities where they freely roam, destroy gardens, dig burrows damaging property, and spread bacteria through their droppings. Green Cay’s balanced management allows visitors to observe these striking reptiles safely while showcasing Florida’s complex wildlife dynamics, making it a unique spot to see iguanas without the problems they cause in unchecked areas.
Planning Your Visit to Green Cay Wetlands and Nature Center
Whether you’re a local or a tourist, Green Cay is an enjoyable place for everyone. Unlike a quick beach stop, this is a place you come to slow down. The Nature Center is indoors (with AC) and the Boardwalk is obviously, outdoors. We find that the majority of your time at Green Cay will be spent outside! The nature center isn’t open every day, so check the schedule if you want to visit it.
Each season offers something special. Winter (November to February) is prime for birdwatching, with cool mornings and tons of migrating birds. Spring (March to May) brings nesting action and blooming plants, so mornings or evenings keep you comfortable. Summer (June to August) is hot and humid but full of green life, with active turtles and alligators. These months we recommend visiting early mornings to avoid summer storms. Fall (September to October) is quieter with some late migrant birds.
They do not have a cafe or picnic spots on the boardwalk or in the nature center, so it’s best to eat before or after your visit. If you’re planning on staying for hours, could pack a cooler with snacks to keep in the car. Right now, you can’t fish or kayak, but those activities are coming with the new expansion.
How Long to Spend at Green Cay Wetlands
The time you spend at Green Cay depends on the weather, season, time of day, and your plans. For example, birdwatchers may spend several hours, while a family with a stroller might just take a quick lap around the boardwalk. Our recommendation, to get the most out of Green Cay, is to plan on spending 90 minutes to two hours there. A relaxed walk on the boardwalk takes about 45 to 60 minutes, giving you time to stop and look for gators and snap photos. Browsing through the nature center adds another 30 to 60 minutes to check out the exhibits.
If you’re into photography or really want to spot wildlife, give yourself up to three hours, especially early in the morning or late afternoon when animals are most active. Another time they like to come out is right after a storm. Winter months, like January and February, are prime for seeing tons of migratory birds, like we mentioned, but there’s always something cool to spot year round!
What to Bring with You to Green Cay Wetlands
Since the majority of your time at Green Cay will be outside, you’ll want to dress accordingly. There will be some areas along the boardwalk with trees and shade, but mostly you will be in direct sunlight. We recommend wearing light colored or UPF clothing, hats, and definitely use sunscreen if you burn easily. Florida weather could be unpredictable, so always check it before heading out. Even if it looks sunny out, you never know when the skies will open and it starts to rain. Doesn’t hurt to throw a compact umbrella or rain ponchos in your bag just in case!
Another thing to plan for (something that comes with being in the wild) is bugs! If mosquitoes love you and tend to gravitate towards you, then you should definitely wear bug spray, repellent bracelets, and even patches or stickers.
The best part of Green Cay is the wildlife. So if you don’t have enough room on your phone, or just want to capture the beautiful scenery, a small digital or wide angle camera would absolutely come in handy. Binoculars will help you see animals that are hiding or far from the boardwalk. The Meta Ray Bans would be great since they protect your eyes and capture the beautiful scenery.
Food and drinks are not allowed, however, being out in the sun you need water. Bring an insulated water bottle, or a foldable one (if you’re traveling). There are no vending machines or water stations along the boardwalk. You don’t want to risk dehydration, it can get hot! If you’re visiting the in the summer, (or if you run hot) consider one of those fans you can wear around your neck. To make it easy for you, we put together a list of items to bring, so you don’t have to think about it!
Recommended Items to Bring to Green Cay Wetlands and Nature Center
Important Rules and Etiquette for Your Visit to Green Cay Wetlands
Part of the charm Green Cay offers is the peacefulness it brings. In order to maintain that integrity, there are some rules that are implemented. Guests are asked to follow these guidelines to keep Green Cay Wetlands clean and safe for animals and humans. To respect the ecosystem, stay on the boardwalk, keep voices low, and do not feed the wildlife. Feeding any animals is strictly prohibited to maintain animal health and safety. Pets (that means dogs!), drones, biking, jogging, smoking, and alcohol are also not permitted, as they disrupt the natural order of the preserve.
Why Green Cay Wetlands is Important to Florida’s Ecosystem
Wetlands are the unsung heroes of Florida’s landscape, and Green Cay exemplifies their importance. Once a pepper farm, the now restored, ecological powerhouse, serves as a natural filtration system in the state. It processes approximately 2 million gallons of treated wastewater daily from the Southern Region Water Reclamation Facility. Through the intricate work of plants, microbes, and bacteria, Green Cay removes pollutants and nutrients, returning cleaner water to the aquifer that supplies Palm Beach County’s drinking water! This process isn’t just a scientific marvel, it’s a cornerstone of regional sustainability, demonstrating how restored ecosystems can support both people and the planet.
Beyond water purification, Green Cay is a biodiversity hub. It provides a sanctuary for over 250 bird species, from wading herons and egrets to noisy common gallinules and rare roseate spoonbills. Alligators, turtles, otters, and even bobcats thrive in its marshes, cypress swamps, and hammock islands. By controlling floods, storing carbon, and fostering wildlife, Green Cay proves that conservation is both practical and essential, making it a must visit for anyone who values Florida’s environmental legacy.
The Phase II Expansion: What’s Next for Green Cay Wetlands
Green Cay is about to get even bigger and better! The Phase II expansion is set to open in late 2026. This $40 to $50 million project will add 63 acres of new wetlands, trails, and lakes, reachable from Flavor Pict Road. Soon, you’ll be able to kayak, paddleboard, fish, or hike new paths, opening up more ways to enjoy the preserve. The Reclamation Education and Center for Advanced Purification, or RECAP, will use cutting edge tech to clean 2 million gallons of water a day, helping keep our water supply strong. A new learning center with a picnic area will make it even easier to learn about conservation. Construction started in April 2024, and it won’t close the current boardwalk, so you can still visit while the expansion takes shape.
