Atlantis reef is a section of the granite reef of the Castle Rocks restricted zone near Partridge Point, so the marine life has been protected for many years and is flourishing. There is no record that the site has been dived before 2011, so it is in pristine condition. The two massive pinnacles marking the site and known as the Pillars of Hercules, were known to exist for some time, as they occasionally show up on the echo sounder of passing boats, but they are a really small target and difficult to find again. However in early September 2011, the dive boat Animal Ocean started investigating the site and reported an exceptionally beautiful area of reef with two impressive pinnacles reaching nearly to the surface but with very small peaks, so they do not break very often, and are in any case to some extent in the lee of the Seal Rock at Partridge Point. Further exploration revealed that the surrounding reef includes some areas of high profile reef near the pinnacles, and further offshore, and extensive medium and low profile reef further inshore, with scattered large boulders.

These areas are situated along the South African Coast and are accessible to the public and are known dive locations to the locals from in and around the area, please respect their local fauna and flora, remember limit your catch and don’t catch your limit.
