Yes, I went to the Zoo in 100+deg weather.You know what? It wasn't all that bad. I took my little buddy there in the Morning. The park is very well shaded and there were several mister zones. We were able to see several of the animals get their breakfast. There were very few people at the park so I got to let my little buddy run free for a bit. We went to the petting Zoo and the goats got lots of toddler attention. Once it got a little warm out, we went to two water/splash pads zones. The first one the Leapin' Lagoon is more open and more suited for older kids. The Yakulla Caverns is great for the little ones. It is better shaded and has a small moat which is perfect for sitting a splashing in. I recommend going with your toddler into the caverns. Can't wait to go again!
