Is there a shuttle from Baoshan Cruise Port to Shanghai Pudong International airport?

I see. You must refer to the Wusongkou International Cruise Terminal in Baoshan District, right? If so, no shuttle bus is available. For the transportation, I suggest you take the free shuttle bus to Baoyang Road metro station first. There you can take metro line 3 to Zhongshan Park. Then transfer to line 2, which will lead to Pudong Airport directly.
