We spent several hours there yesterday and really enjoyed it. We paid our $10 (a pretty small fee, really) and took a quick walk on one of the trails. I started to get pretty discouraged because the signs and some of the cages are pretty run down. Then we went to the info center for the reptile show. Since it was a small group, they invited us along as they fed the animals. He introduced us to each one and told us how they came to be at Calusa. Each animal was a rescue , or a pet that someone had to abandon. Te bald eagles, and Tails the fox were my favorite. We got to take pictures with several of the animals. Overall, the place clearly needs some help (lots of construction materials and what should be "backstage" was out in the open). The planetarium was good too, included in the price and interesting shows!
Come here and spend the time to really see what they have to offer. Don't judge the quality of the work they are doing by the condition of some of the place. We had a great time.
