The BirdLife fact sheet states the 12 ha (30 acres) island is only 58 m (190 ft) above sea level. It adds that the island is rocky and “supports minimal vegetation”. The island runs 700 m (2,300 ft) along a northwest, southeast axis and is about 360 m (1,180 ft) wide at its broadest – along the west coast. Its highest point is halfway along the north coast. Bartholomeu Dias planted a padrão and celebrated Mass on the island in March 1488. With 22,000 African penguins breeding on the island it is the largest breeding colony of this penguin species on the planet. Boat trips out of Port Elizabeth can take guests to see these birds.
