The purpose of this paper is to discuss the tourism developing opportunity and pattern of the Shengsi Islands and Islets under the background that China has planned to build a deep water wharf in the Dayangshan and Xiaoyangshan Islands in Shengsi and that Shanghai is to become an international shipping center. Taking into consideration the tourism developing experience of seashore and seaport in the world, the author suggests that the Shengsi government should choose the big-project-driving developing pattern to co-develop the bridge, the seaport and the scenery relating to the project as tourism resource, which includes establishing brand-new eco-tourism distributing structures, producing special and charming tourism products, planning tourism hits around the Pacific Ocean, offering the service towards Shanghai as well as the whole world and building as a whole three tourism functioning areas——Yangshan Port sightseeing, Shengsi eco-vacation and Hualu-Gousheng Island's special tourism, which can also promote the tourism development of the islands and sea areas nearby.
