Scuba Diving in Hong Kong

Good to Know

• Hong Kong diving is a genuine day-boat activity, not a liveaboard destination — trips depart from Sai Kung-area piers and most sites are reached within 30–90 minutes.
• Visibility is the honest weak point: even on a good day it's often only around 15 meters, and can drop to near-zero after summer rain and monsoon runoff — winter and spring are the reliable windows for clearer water.
• Marine parks like Hoi Ha Wan and the Ninepin Islands have restricted or designated anchoring points, so independent boaters need to follow marked mooring rules rather than anchoring freely.
• Local dive operators will check your certification card before boarding, so bring physical or digital proof of your highest qualification.
• Underwater visibility in Hong Kong is genuinely poor by tropical standards — divers commonly report around 3m on a good day — so local certification dives are more about skills practice than sightseeing; many divers here use it as training before diving in clearer destinations.
• Nearly all beginner open-water certification dives (both scuba and freediving) happen around Sai Kung in the New Territories, so budget travel time out from central Hong Kong Island/Kowloon on training days.
• Course fees at most shops cover gear rental, pool time, and boat/dive fees, but transportation to the pool or pier is typically NOT included — factor that into your budget.
• If you want both scuba and freediving credentials, a few operators (e.g. Scuba Hong Kong) teach both PADI and AIDA courses, which can simplify scheduling if you want to try both.
