The zoo offers daily activities, including duck feeding, and offers Eco-Exploration Backpacks Tours filled with activities for $2 per pack per visit, available in the gift shop. These would be great for homeschooling parents.

You can view a list of all 200 animals (over 70 species) online.

We paid: $4. I paid $3 for adult, non-resident admission. The kids were free, and we spent $1 to split the rental of an eco-exploration backpack with our friends.

Our experience:
Cosley is a small zoo (in fact, Cooper calls it “the small zoo” because we spend so much time at Brookfield) and you won’t exactly find lions and tigers and bears (oh my), but the kids don’t seem to have any less fun. It’s the perfect size for toddlers because there’s plenty to do for a few hours. It’s not too crowded (even when the lot is pretty full), and the kids can see the animals up close. Because it’s smaller it’s a little easier to see more animals; everything’s a little closer together and it doesn’t take quite as long to get from exhibit to exhibit.
We rented an eco-exploration backpack about “senses” for $2 during our most recent visit and enjoyed that. Some of the activities were for older kids (the starting age was four and we had two 3-year-olds and two 1-year-olds), but most of it was interesting for all the kids. They got to look through binoculars and a magnifying glass, try to identify different scents, and try to identify the objects in the containers based on the sounds they made.

The staff at the zoo was very friendly and helpful. In fact, I got the feeling that if your 1-year-old just disappeared while you were focused on scolding your 3-year-old for running away, the entire staff of the zoo would come rushing to help, with management at the front gate and all the employees reporting from different areas of the zoo by walkie talkie, until he was found, safe and sound. But I’m just speculating, of course, because something like that would never happen to a supermom like me. Of course.
