Hainan Province dive sites

Wuzhizhou Island caters to all levels including complete beginners. Introductory discover scuba diving experiences are available and very popular with domestic tourists visiting Sanya. For certified divers, Open Water certification is sufficient for most sites as maximum depths are around 25 metres with generally mild conditions. Several PADI-affiliated dive centres on the island offer certification courses in both Mandarin and English.

Wuzhizhou Island offers solid tropical reef diving that is excellent by Chinese standards, though it does not match the biodiversity or visibility of top Southeast Asian destinations like Raja Ampat or Sipadan. What it offers is convenience for China-based divers, warm water year-round, healthy coral formations, and well-managed dive operations. For domestic divers seeking their first tropical reef experience without leaving China, it is the best option available.

The best diving conditions run from April to November, with June to September being peak season for visibility and water temperature. Typhoon season from July to October can occasionally disrupt diving, though the island's location offers some protection. Winter months from December to March bring cooler water temperatures around 22-24 degrees Celsius and reduced visibility, but diving remains possible year-round.

As of the most recent regulations, diving in the Xisha Islands is restricted to Chinese nationals and is managed through approved liveaboard operators departing from Hainan. Foreign visitors have not been permitted to join diving expeditions, though tourism regulations in the area have evolved over time. Anyone interested should check the latest policies with operators based in Sanya or Haikou. The administrative city of Sansha, established on Woody Island, manages tourism permits for the archipelago.

Approved liveaboard vessels depart from Sanya on Hainan Island. The voyage to the Xisha group takes approximately fifteen to twenty hours depending on sea conditions and the specific destination atoll. Itineraries typically run five to seven days covering multiple atolls and reef systems. Due to the remoteness and limited medical facilities, operators require participants to carry valid dive insurance and demonstrate advanced diving certification.
