Scuba Diving & Snorkeling

No matter it's summer or winter, diving is an essential activity for tourists visiting Sanya, Hainan. The water quality may be slightly poorer in winter compared to summer. There are six major diving spots in and near Sanya: Yalong Bay, Baifu Bay, Wuzhizhou Island, Boundary Island (Fenjiezhou Island), Dazhou Island and Jiajing Island. Among these spots, Yalong Bay is mainly for deep diving, Baifu Bay and Jiajing Island are ideal for snorkeling, while both deep diving and snorkeling are suitable at Wuzhizhou Island and Boundary Island.


Dazhou Island, also known as Yanwo Island, is located on the sea off the southeast of Wanning City, Hainan Province, around 90m drive from Sanya. It is the only national-level marine nature reserve on the coastal line of Hainan and the largest uninhabited island on the coastal line. The Island consists of two islands and three peaks, with an area of about 4.36 square kilometers and a highest peak of 289 meters. It is the only habitat for Golden Swallows in China. Dazhou Island is also a popular tourist destination for its beautiful sea views. The island is divided into North Xiaoling, South Daling, and is connected by a 500-meter-long beach in the middle. The island is known for its unique rock formations and clear surrounding waters, with visibility of 5 to 10 meters underwater on average. The underwater world is teeming with diverse marine life, making it suitable for activities such as diving, underwater exploration, and photography.

1. Yalong Bay: Suitable for diving throughout the year, with high visibility and diverse coral species.

2. Wuzhizhou Island: The visibility of seawater ranges from 6 to 27 meters, with well-preserved coral reefs. It is one of the few islands in the world that has no reefs but is a mixture of pebbles. The disadvantage is that there are more tourists, and the water may be turbid in winter.

3. Jiajing Island and Dazhou Island: Surrounded by mountains on three sides and the sea on one side, offering high visibility of seawater. Good for snorkeling.
