The small settlement of Gansbaai was formerly best known as a fishing village, but is now renowned as one of the few places in South Africa – and worldwide – where you can go cage diving with the ocean’s most formidable predators, Great White Sharks. Vessels leave from Gansbaai’s Kleinbaai Harbour, travelling for roughly 20 minutes to a deep gully running between two islands inhabited by countless seals – the Great White’s favourite food source. As a result the channel, appropriately dubbed ‘Shark Alley’, attracts high numbers of Great Whites and offers excellent viewing of these usually elusive animals.
