There are indeed beaches suitable for camping around Shenzhen. And there are quite a few.
If I personally recommend it. The following are suitable for camping, but there are activities or weather and personal circumstances may not allow it. You can check the climate and so on before you go.
Xichong, Peizaijiao, Dajia Island and Yangmeikeng Valley Valley Beach.
Hsi Wu
Xichong Beach is one of the eight most beautiful beaches in China and the largest beach in Shenzhen. The seawater in Xichong is kept around 22.4℃ all the year round, and it will be more comfortable in spring, summer and autumn. At the same time, because Xichong is far away from the city and people, it is quiet.
The facilities here are also quite perfect. There are wooden houses, tents for rent, beach volleyball, speedboats, bonfires and barbecues. It&;s quite expensive. You have to pay for bathing and changing clothes in the toilet!
Address: Shenzhen Dapeng New District
northern suburbs
Shenzhen Beizaijiao Beach is located in the east of Shenzhen, close to the famous xiaomeisha Beach. The beaches here are fresh and clean, and the sea water is crystal clear.
