Before you drive into Everglades National Park, stop here. The Ernest F. Coe Visitor Center sits right at the main entrance off SR-9336 in Homestead, and it's genuinely worth 30 to 45 minutes of your time before you head deeper into the park.
Inside, you'll find interactive exhibits that work for both kids and adults. Hands-on displays explain the ecosystem, the wildlife, and the history of how this place came to be protected. The free short film is worth catching. It gives you real context from multiple perspectives, and you'll appreciate the park more for having watched it. Rangers are on hand to answer questions and help you figure out what to do based on how much time you have.
The gift shop carries souvenirs, snacks, drinks, and ice cream. It's not a full café, so if you're planning a long day in the park, bring your own food and water. (There are no restaurants inside the park itself, so this is your last real stop before you're on your own.)
Right outside the building, there's a clear pond that often draws wading birds close enough to photograph without a telephoto lens. No park pass is required to access the visitor center itself, which makes it a low-commitment first look at the Everglades for anyone still deciding how deep they want to go.
