At the park, you get to drive out with a group (or on your own if you pay enough) and actually be out where the animals are. What’s interesting is that groups of animals stay together just like they were in a smaller enclosure. So, while the giraffes were free to roam wherever they like, they all seem to roam together.
Up in the back, you can see the big balloon ride and the lodges, neither of which I’ve used personally.
