St Croix in Port Elizabeth is home to the largest African penguin colony in the world, close to 50 per cent of the world population.
At the last count there were 22,000 birds. It lies 4 km offshore between the Coega and Sundays River mouths, part of a group of coastal island clustered roughly into two groups of three islands each.
St Croix, a 12 ha rocky island, lies close to the smaller Jahleel and Brenton Rocks. It is made up of a series of quartzitic outcrops that rise as high as 53 metres on St Croix.
Today St Croix is a penguin sanctuary. Boats are not allowed to land on the group of islands, although some charter boats cruise close enough to enable one to see the penguins quite easily.
