The price for adults is 80 yuan. However, the fare for children over 1.20 meters is half that for adults, especially for children under 1.20 meters, Guangzhou Zoo is free.
By the way, Guangzhou Zoo is very big and beautiful. You can't miss it. But you'd better not go to the zoo on weekends. Because there are too many people visiting on weekends, and you may encounter some unexpected troubles.
Finally, I wish you a pleasant visit.
