Position

• 1 Stern Reef: S34°13.164’ E018°28.032’ — An extensive area of high to low relief granite corestones on a sand bottom, marked by a rock which breaks the surface at some states of the tide. About 260 m South of Spaniard Rock, towards Miller’s Point.

This site is in a Marine Protected Area (2004). A permit is required.

Depth

Maximum depth is about 14 m, and the top of the reef breaks surface at low tide. Other rocks are lower. but the bottom is fairly level.

Topography

Coarse sand bottom with big granite boulders and reef. Largely fairly high to high relief with some low areas. Quite nice, specially just to seaward of the blinder, with quite a nice swim-through and some deep gullies between boulders. The reef has not yet been surveyed, but is thought to extend at least 50m to the north, east and west of the breakers. The bottom to the south is sandy.

Geology: Late Pre-Cambrian granite of the Peninsula pluton.

Conditions

Shore diving is limited by entry and exit conditions. Boat dives may be done in bigger swell with more surge, but the site is fairly shallow and surge will usually reach all the way down.

Facilities

Same parking area as for Spaniard Rock

Optional shore dive from Rocklands Point: Parking at side of main road on gravel shoulder. Access not easy and entry/exit a bit rough if there is much swell.

Can also be done as a boat dive from Miller's Point slipway or Simon's Town jetty. The site is easy to find as there is almost always a break over the top of the reef.
