Sylvan Heights is a one mile loop walk through enclosures with birds from all different continents. As you walk through the North America section through to Australia, you'll see the domestic to the exotic - from turkeys and owls, to kookaburras and toucans.
I took all 3 of my kids to Sylvan and all four of us had a blast pointing out all of the amazingly colorful specimens. Even my five year-old girl admitted she had a good time after expecting it to be a boring trip. There was enough to see to keep my 8 month-old from fussing about being in the stroller. And my two year-old lagged behind at every exhibit trying to absorb every last bit of the experience.
You start your visit at the visitor's center where you buy your tickets. It was $9 for me and $5 for my five year-old ( age 3 and under get in free). There was an incubator in the visitor's center with several different species of bird's eggs in it, along with two newly hatched ducklings. A member of the Park staff took one of the ducklings out for my kids to pet. There is also a small gift shop in the visitor's center.
Next, you move outside to start exploring the different enclosures along the trail. The trail is hard-packed sand so it's stroller accessible but if you visit after a significant rain you should expect some mud.
All of the exhibits are outside so you'll also want to keep an eye on the weather - the day we were there it was hot and humid. Some of the enclosures have gates that allow you to walk right in. While we were in one of these, a medium sized blue bird came right up to us. The bird was so close my two year-old son could have touched it. And though he didn't touch it, he did back it into a corner where it promptly flapped its' wings and scared my son to death. But my son was undaunted by the experience and was willing to enter another enclosure later on.
