This reef has a sandy bottom and rock outcrops. Main features of the reef are the wall, an archway and a swim through. The reef is situated a short distance, directly opposite the Noordhoek launch site. Many fish tend to gather on this reef. Most notably the Red Steenbras and Dageraad, both of whose numbers have been severely depleted due to over fishing. An occasional Raggie have been sighted on and around Mark 4. There is purple seaweed and good coral growth.
