Boasting the highest concentration of Great White Sharks in the world, Shark Alley is a sea channel off the South-East coast of South Africa. This makes it one of the top shark cage-diving sites internationally. The dive site is accessed from Gansbaai, the Great White Shark capital of the world, about 160 km from Cape Town.
Nearby Dyer Island is home to thousands of Cape Fur Seals, creating a feast of prey for the Great White Sharks. Shark Diving companies are eager to take tourists and locals alike, for a truly thrilling adventure at sea. It often happens that the sharks pass so near the boat, that you don’t even have to be in the water to get a great view of these magnificent predators. Shark Alley was recently featured in the movie Dark Tide with Halle Berry. Permits are also given to documentary filmmakers and researches to do their work. The shark activity in the area makes it perfect for these purposes.
The best dive times are the winter months from April to September when a huge number of Great White Sharks are drawn to the pungent smell of the thousands of seals living on Geyser Rock. Ground weather is colder but the water temperature is generally warmer, making for more shark activity. The water is baited with Tuna and other fish-based products to attract sharks. This does not cause a feeding frenzy but keeps the sharks interested in the bait available around the boat. Without the bait, the sharks tend to lose interest rather quickly and move away from the boat.
The term Marine Big Five originated from the Gansbaai coast with huge amounts of sharks, whales, dolphins, penguins, and seals that frequent the waters there. A complete marine game viewing tour can be had near Gansbaai at the right times. Shark Alley is a must do for thrill seekers of all ages.
