Île des Pingouins, or Penguin Island, is an uninhabited island in the subantarctic Crozet Archipelago of the southern Indian Ocean. It is small — just 1 square mile (3 sq. km) — with coastal cliffs ranging from 164 to 984 feet (50-300 meters) tall, making it virtually inaccessible by sea. The island is an important nesting site for seabirds and has an exceptionally high density of avian residents, including a million pairs of macaroni penguins.
