Scuba diving quarry

Recreational dive sites include specific places that recreational scuba divers go to enjoy the underwater environment. This includes publicly accessible recreational diver training sites and technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of the recreational diving service industry, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.

There are a wide range of underwater features which may contribute to the popularity of a dive site:

The Cape Peninsula marks the boundary between the cool temperate South-western Cape bioregion, which extends from Cape Columbine to Cape Point, and is dominated by the cold Benguela current, and the warm temperate Agulhas inshore marine bioregion to the east of Cape Point which extends eastwards to the Mbashe River. The break at Cape Point is very distinct in the inshore depth ranges, and the waters of the east and west sides of the peninsula support noticeably different ecologies, though there is a significant overlap of resident organisms. There are a large proportion of species endemic to South Africa along this coastline.

Coral reef areas

Scuba diving quarries are depleted or abandoned rock quarries that have been allowed to fill with ground water, and rededicated to the purpose of scuba diving. They offer deep, clean, clear, still, fresh water with excellent visibility, and have no currents or undertow. They are often used as training sites for new divers, where classes and certification dives are carried out. Scuba diving quarries are often stocked with fish, for the divers to enjoy, and often feature contrived “wreck” sites, such as sunken boats, cars, and aircraft for divers to explore while diving. Many have some manner of dive shop on site to offer air fills, replacement diving equipment, and rentals. Oftentimes lodging or camping is available on site as well.
