You will be spoilt for choice when you want to experience the “Big 5” Marine life in Gansbaai. Found only in Gansbaai, Dyer Island is located 8 km from shore and is an access controlled Important Bird Area (IBA) for the conservation of its many resident bird species, including African penguins. Adjacent to Dyer Island is Geyser Rock, home to a 60,000 strong Cape fur seal colony. These seals are present all year round. You can book with tour operators that will take you into the channel of water between Dyer Island and Geyser Rock known as the world famous ‘Shark Alley’. They will then take you to the whale hot-spots in the bay.
