Are there any trains from Guangzhou International Airport to the Zoo?

Yes! Take metro line 3 from CAN to Jiahewanggang Station. Next, change to metro line 2 to GZ Railway Station. Then, change to metro line 5 to the zoo.

In general, the trains are available from 6:00 to 23:00 at intervals of about 5 minutes every day. The whole trip takes about 50 minutes, and the fare totals CNY 8.

You may spend one full day there. :)

Thanks to Cherryl. My next question is:

We don't have a full to tour the entire zoo. Can we not go straight to where the baby pandas are and how time is needed just to see and hug them? We need to back at the airport by 11 am.

Well, I'm afraid that you cannot hug the panda in the zoo. Tourists just can look these cute animals from a distance. In this way, you can use around 1.5 hours to tour around the zoo. Remember to come back to the airport at least 2 hours in advance before the departure.
