Hop in your car and go south to Jinshan beach, about 60km south to Shanghai downtown. Say goodbye to the fake-sand and let the natural sea view wash your fatigue away. Apart from swimming and sunbathing, there are many activities for both adults and kids – try water bicycling, boating, kayaking and even sailing and fishing. Preregistration is necessary via Youhuma.
Alternatively, take Line 1 to Lianhua Lu and then get on the 莲石专线 (lianshi zhuanxian) bus from just outside (90 minutes, 8RMB), until you see the main entrance to the beach on Fuchuan Lu.
