White Shark Cage Diving/Shark Alley
Dyer Island is the largest of the group of islands situated 8km/5mi from Gansbaai. Dyer Island is a protected bird sanctuary and nature reserve belonging to Cape Nature, and has no visitor access facilities. Recently the Island has become a fantastic location for shark diving. The narrow channel (152m/500ft wide and 610m/2000ft long) between Geyser rock and Dyer Island is now known as "Shark alley" or "Dyer Straits", because of high numbers of sharks in this area. Great White Sharks are the world’s largest predatory fish, reaching over 6m/20ft in length. They are the ocean’s top predator and are the most feared denizen of the sea.
