@Austin the Sengi I'd be interested to know how often the Giant Pandas have access to this enclosure, or if they even use it at all. Maybe on slightly cooler days? Chiang Mai (currently lacking Giant Pandas), Negara and River Wonders all keep Giant Pandas almost entirely indoors due to the tropical heat.
However, Taman Safari I Bogor in Indonesia has an astonishingly impressive Giant Panda complex set high in the chilly mountains and it's part of the zoo but visitors can only access the pandas via a free bus/tram. I'll eventually upload photos onto ZooChat and the complex is spectacular, complete with at least two indoor and two outdoor Giant Panda yards.
