I don't know how the reviewer below missed all the water fountains. They're literally everywhere. Right off the top of my head, there's one near the hoofed animals, outside the snake building, near the food center, tropical bird house, and komodo dragon. They are clearly marked on the maps as well. There's also misters and a splash pad. I think someone just had a bad day below. He also criticized the dinosaur exhibit. That's a temporary traveling exhibit.

We love the Houston Zoo, the family membership pays for itself after a couple of visits. After the San Diego zoo system, this is my favorite one to visit. Educational, well thought out and well shaded with air conditioned indoor exhibits for those blazing summer days. Lots of interactive fun for the kids too! The African Forest is a must! Go first thing in the morning when the animals are most active. If you're lucky you can hear the kookaburra sing!

Elder son: Loves the bug and the snake house!
Younger son: Loves the aquarium and watching the piranhas at feeding time! It's as frenzied as you'd imagine.
