The site is just outside False Bay, southwest of Cape Point, in the Table Mountain Marine Protected Area. It is not dived often as it is a long ride, but it may be a good second dive after the Lusitania.
- 1 Anvil Rock 3m pinnacle: S34°22.218' E18°31.090'
- 2 Anvil Rock caves: Approx 20m deep, area of nice caves/swim-throughs: S34°22.244' E18°31.068'
This site is in a Marine Protected Area (2004). A permit is required.
The name "Anvil Rock" is marked on the nautical charts of the area as a known navigational hazard.
Maximum depth is deeper than 20 m. and the top of the pinnacle is about 3 m. (Average depth of a dive is likely to be about 18 m.)
Not much is known about visibility at the site, but it is probably much like Bellows Rock.
There is a large, flat-topped shallow pinnacle rising to about 3 m, with a sheer wall on the south side dropping to more than 20 m. The west, nort and east sides slope more gradually. There appears to be a sand patch to the south east which was visible as a light patch from the 15 m contour. Depth of this sand patch is estimated at more than 20 m
A deeper pair of pinnacles at about 13 m on top lies a bit further south, where the bottom is a bit deeper than 21 m They are quite rugged and sheer sided, with some small caves and tight swim-throughs.
Geology: Precambrian granite corestones of the Peninsula pluton.
The site is exposed to wind and waves from all directions, so should be dived in calm winds and low swell. There may be strong surge and a slight current.
Access is by boat, usually from Simon's Town or the Millers Point slipway. The site is about (distance)km from Simon's Town jetty, or (distance)km from Miller's Point
The marine life is typical False Bay invertebrates, with large numbers of nippled sea fans, sponges and soft corals. The upper surfaces have quite heavy kelp growth, mostly split-fan kelp, and large red-bait pods in the shallower areas. There is a predominance of purples and blues over large parts of the reef, due to thriving purple soft coral and dentate moss animals.
Macro photography is most likely toproduce good results, but wide angle may be good if the water is clean.
At the south pinnacles, spend some time at about 20m, where there are a few small caves and swim-throughs.
No special hazards are known, though the surge may be quite strong.
No special skills required, but much of the site is deeper than 18m, so it is more suited to advanced divers.
A light for looking into the holes and swim-throughs, and a DSMB and reel, to let the boat know where you are surfacing. If there is a current, you could drift quite a long way during the ascent, an it is a long way to shore.
