This excellent aquarium features denizens of the deep from the cold and the warm oceans that border the Cape Peninsula. It's a chance to see penguins, turtles, an astounding kelp forest open to the sky, and pools in which kids can touch sea creatures. Qualified divers can get into the water for a closer look (R870 including dive gear).
