Île Saint-Paul is a small, uninhabited island located in the southern Indian Ocean, part of the French Southern and Antarctic Lands. It covers an area of about 6.5 square kilometers and is known for its rugged terrain and volcanic origin. The island is surrounded by steep cliffs and features a central caldera, which is a large volcanic crater. The island is primarily used for scientific research and is home to various seabird species, including the Indian Ocean albatross. Access to Île Saint-Paul is restricted, and it is often visited by researchers and conservationists studying its unique ecosystem and wildlife.
