Tourist Line 4
Operates between Shanghai Stadium and the Grand View Garden in the southwest Qingpu District, covering numerous places of interest in Qingpu, including the famous Zhujiajiao Ancient Water Town.
Route: Shanghai Stadium (07:00 - 15:00) <---> Shanghai Zoo <---> Shanghai Horsemanship Athletic Field <---> Qushui Garden <---> Zhujiajiao <---> Water Sports Center <---> Baoguo Temple <---> Fork Club <---> Grand View Garden (09:10 - 16:30)
Zhujiajiao is a stop and the bus goes on to the Grand View Garden.
Of the two, the bus departing from People's Square Pu'an Road sounds more attractive. I've found this photo blog (in Japanese) by someone who took the tour a year ago. It was on Saturday and after waiting for 1.5 hr at the stadium they decided to take a taxi to Zhujiajiao instead. They took the Huzhu Express bus back to Shanghai. You can see the pink bus if you scroll down.
