As it happens, I am also a person who loves the sea. I recommend the islands and beaches to you. I have written a detailed travel note about seeing the sea around Guangzhou before. You can go and have a look.
The nearest island is Qi &;ao Island in Zhuhai.
There is a lighthouse full of literature and art, a seaside, sea breeze, and better accommodation, but if it is the peak season, book it in advance!
2 Huizhou delta island
This is really an unpopular island, mainly because xunliao bay has to board another ship. Moreover, this island is not big, but there are snorkeling, speedboat and other marine projects. What makes this island different is that its sea water is clear lake blue.
(Pro-test is suitable for daze)
3 Zhuhai Wailingding Island
It is very suitable for a large group of people to camp and have a barbecue. Although this island has a long journey, it can be regarded as an island with a good original appearance.
4 Dongshan Island a little further away.
In Yunxiao Station, Fujian Province, the high-speed train has been in use for 3.5 hours, and it has recently become more and more popular becaus《左耳》. But I have to marvel that the sea here is beautiful, the people here are nice, and Tongling town here really retains the buildings of the Qing Dynasty.
5 Jiangmen Shangxiachuan Island
I heard that the scenery of Xiachuan Island is more beautiful, so I went to Xiachuan Island. Well, because the weather is very important, it was cloudy the day I went there, and it rained the next day.
However, it was not bad to see the sunset that day. Rent a motorcycle and go to a place far away from the accommodation area. The scenery is better.
Above, I hope to adopt. Of course, there are many islands. Lamma Island, Dongshan Island and delta island can be said to be my strong recommendation.
