You can fly from Guangzhou to Putuo to Ningbo or Zhoushan. The most convenient way is to fly to Putuo Mountain Airport in Zhoushan. There will be a corresponding airport bus on every flight landing from this airport to the boat pier of Putuo Mountain in Zhujiajian Island, which takes less than 10 minutes by car, but there is only one round-trip flight from Guangzhou to Zhoushan. The departure time of Guangzhou is particularly early, but three days is just right. The middle is equivalent to nearly two full-day mountain walking time, so you can travel around the whole island and Luojia Mountain more leisurely.
