Went here as part of a three in one Miami tour and this was definitely the most disappointing part. The airboat ride was quite short and we saw no wildlife apart from a flock of birds which was not identified by the guide. I understand that, by its very nature, wildlife sightings cannot be guaranteed. However, to be told that the lack of it was because of the "cool" weather, the animals wouldn't come out, and then to read in these reviews that other tourists had been told on different occasions was that it was too hot to bring out the wildlife, was a bit much. I'm sure that its the airboats themselves that scare off the animals. The guide was touting for tips at the end - I didn't see any of the disgruntled passengers give him any and he was sarcastically saying "glad you enjoyed the boat trip" as we left.
On to the "show". Again the excuse that it was too cold was trotted out to explain the alligators' lack of interaction with the trainer, so - no show!
The worst part of the experience was when I asked the trainer if the show alligators actually lived in the show pool in which we saw them. The pool is crescent-shaped with not particularly clean water, no vegetation of any sort and too small to accommodate the number of alligators there. The trainer replied that yes, they did live there, as to take them out (to anywhere decent) would lead to the loss of "interactivity" between him and the 'gators. I think this is disgraceful in the modern age.
I would like to see the Everglades properly, from a proper boat and without the animals being caged in such an offensive way. I believe that this can be achieved in other parts of the Everglades, but it seems you do need your own transport to achieve this. In the meantime, I recommend that animal lovers steer clear of Everglades Safari Park.
