riding tours through the zoo?

Train🚂

Shuttles are closed but ride the train, it's only $5 each person but well worth it

There are tours, but nothing to ride through the entire zoo.

Shuttles just that, shuttle you to a point. Train ride is for kids and is very short. Not really for any viewing.

You can sign up online for a VIP tour for 7 people 5 hour tour including lunch I believe it's $1,500.

I only know of 1 shuttle near the entrance that take you to 1 destination and back. It will take you to the farthest country from the entrance and straight back no other stops.

I want to say each section has its own shuttle. I know there's a shuttle for the North American section because it's right at the entrance.

You can take a train trip through the zoo, with additional costs. However I don’t believe it is throughout the entirety of the zoo.
