About 滘西洲
滘西洲 Kau Sai Chau is a shallow Sai Kung boat dive built around coral patches, a sandy middle section and small-reef structure that suits easy paced exploration. The site is known for juvenile fish schools and occasional frogfish, with the shallow coral zone making it a strong choice for newer divers and relaxed training days. Visibility is the main variable, so the dive works best when you want a compact, low-stress route rather than a long swim.

Scuba
Depth ranges described from shallow coral at 1–3 m to around 10 m at the deeper sections mentioned.
Freedive
Possible for competent freedivers, but the site is better known as an easy scuba and snorkel training area than a pure breath-hold location.
Snorkel
One of the better snorkel-friendly entries in the area on calm days because the coral sits shallow.
