Diving the Cape Peninsula and False Bay/Pie Rock
The dive site Pie Rock is an offshore rocky reef in the Castle Rocks restricted zone on the Cape Peninsula side of False Bay, near Cape Town in the Western Cape province of South Africa.
It is a spectacular dive in good visibility, and large numbers of fish may be seen.
The site is generally considered a boat dive. Launch at Miller’s point. It could be dived from shore entry at Castle Rocks, but would require a 750m swim each way. For a shore dive use a SMB as boat traffic in the area can be heavy on a good day. Bearing from Castle Rocks north entry approximately 120° magnetic.
About 760m from North Entry at Castle Rocks. Bearing 353° True (017° magnetic) to Bakoven Rock, approximately 278° True (302° magnetic) to North side of Castle Rocks.
This site is in a Marine Protected Area (2009). A permit is required.
The site is called "Pie Rock" because one of the larger rocks in the area is said to look a bit like a giant wedge of pie.
Maximum depth is about 25m. Top of the pinnacle is at 5m. Average depth on a dive is about 15m.
Large granite corestone outcrops and boulders. There is a pinnacle at the east side of the site, which is also the deeper side.
Geology: Granite of the Pre-Cambrian Peninsula pluton.
The site is moderately protected from south westerly swell. South east chop may make it unpleasant on the surface, but it may be quiet below the wave base, however a strong south easter or one that blows for a long time will push up a swell that will make it unpleasant all the way down. Generally considered a winter dive site but there are also occasional opportunities in autumn and spring.
Large numbers of false corals, feather stars, colonial ascidians, red sea cucumbers and colonial hydroids. A reasonable variety of fish, sometimes in fairly large shoals.
