牛尾洲 Shelter Island is a shallow boat dive off Sai Kung, with its best coral in the inner bay and a transition to sandy or muddy bottom farther out. The sheltered water makes it a beginner-friendly stop for scuba and snorkeling, with calm entries and strong macro potential, but boat traffic and ghost nets mean the ascent deserves attention on the surface.

Safety Notes
Stay aware of boat traffic on ascent, and watch for ghost nets and other entanglement hazards near the reef.
Access Restrictions
The main coral area is a no-anchoring zone, so boat handling needs to stay clear of the marked reef.
Legal Notes
Do not anchor in the protected coral zone or disturb reef habitat and marine debris.

Scuba Diving
Best depth for scuba is around 3–5 m where the coral area is located.
