The dive site '''Stonehenge''' is an offshore rocky reef in the Karbonkelberg headland area on the Atlantic seaboard of the Cape Peninsula, near Cape Town in the Western Cape province of South Africa.
It is a good site for varied topography, biodiversity and depth variation.
South of Duiker Point, below Karbonkelberg
This site is in a Marine Protected Area (
The area is named "Stonehenge" after a more or less circular ring of rocks which break the surface near a much larger rock which is shown on the charts.
Maximum depth is over 22m, with an average of about 12m to 15m
The site is exposed to south westerly swells, so best when the south west swell component is low and short. This may occur after south easterly winds. The site is usually at it's best in summer, but there may also be occasional opportunities in autumn or early winter.
This is an area which sometimes has upwellings, caused by strong south easterly winds, resulting in cold clear water, and may then have a plankton bloom, which will reduce the visibility again.

Typical of the big reefs of the Atlantic coast. There is a heavy growth of red bait in shallow areas, Kelp on top surfaces in moderate depths, and fairly bare rock with urchins on relatively flat deep surfaces. Walls, overhangs and other steep surfaces are covered with wide variety of sponges, corals, ascidians and other invertebrates.
Good photographic site.
A light can be useful to look into dark places and to restore colour at depth. A compass can help keep track of your position, and a DSMB is handy to allow the boat to keep track of ascending divers. Nitrox can extend your no-decompression time if you are well insulated.
