The zoo is called Ardastra Gardens. Disney does an excursion, but my family did it on our own. The cab ride took about 5 minutes from the pier. It's located next to Fort Charlotte. I wasn't really looking forward to going, but we had a blast. We watched their trained flamingo show, fed lorakeets, and enjoyed walking around the gardens and seeing the exhibits. We spent about an hour and a half. We'd go again.
