Just 4 km (2.5 miles) from Mahé lies the island of Sainte Anne. This is the largest island in the marine park, and was the first island in the Seychelles that the French discovered in 1770. These days, it plays a special role in the natural and cultural heritage of the Seychelles. The marine park includes Sainte Anne, along with Cerf Island, Round Island, Marianne Island, and Long Island, and is famous for its excellent snorkelling conditions.
