If you don't drive by yourself, you can go directly to Dishui Lake from Lingang Station, near Maritime University (take Huancheng No.1 Road). Of course, you can also go to Donghai Bridge and take a bus directly to Yangshan Island.
At present, the port is short of supporting facilities, but it is also a rare place with good air in Shanghai. Blow the sea breeze, see the artificial lake and lie on the grass to listen to music. . .
food: there is a Rosen restaurant and a gourmet forest in the exhibition center. Besides, Jinjiang Kitchen is also a good choice.
have fun!
