Hong Kong :: Breaker Reef

About the Dive Site
This area is also known as Shek Ngau Chau. The site consists of a large cluster of rocks near the middle of Mirs Bay. Some of the reef dries at low tide adding to the diversity of marine life that can be found there. It is one of the best dive sites in Hong Kong if you like coral and a large variety of sea life. Large fish frequent this area, including sharks. Nudibranchs and featherstars are common. The normal dive practice is to swim along the long deep gullies that make up the reef.

An easterly wind usually makes this site difficult to dive and visibility deteriorates rapidly.

Hazards & Warnings
The normal warnings for diving in Hong Kong apply to this area.

This area is fairly isolated so special consideration needs to be given to weather conditions.

Sections of the reef can have a lot of line and net fishermen trying their luck if the weather is good.

There is a lot of old lines and nets in this area so care needs to be taken to avoid entanglement.

This area is prone to large swells that may be larger than the water movement visible from the surface.

There have been numerous reports of reasonable sized sharks being sighted in this area. Normal shark precautions should always be applied when diving in this area.

The area is prone to quick weather changes, so it is important that some sort of diver recall procedure is agreed on before starting dives here.

A diver marker and/or emergency diver "safety sausage" is necessary since tidal flow may separate divers from boats.

Getting to Breaker Reef
You need a large private boat to reach this dive site. The closest convenient pier is either at Hebe Haven (Pak Sha Wan) or Sai Kung.

It is important to understand that this area is very exposed. Any easterly wind will normally stir up this area making it rough for boats to get there and even worse for divers trying to enjoy the area.

This area is considered very remote and close to the Hong Kong/Chinese border/territorial waters.
