The Houston Zoo is a great bargain. I lived in San Diego for a while and the zoo there was extremely expensive. The Houston Zoo is only $7 for adults and $3 for children aged 3 to 12. It is open year round. The zoo is pretty big, I think it is about 55 acres. A good day of walking for sure. The zoo has some educational and conservation resources. The new children's area is great for small children. Most children love the petting zoo. I recommend going in the late fall, winter or early spring. The heat of the summer can be brutal and the animals do not move much.
