Saint Barth%C3%A9lemy:

There are as many as 22 public beaches (most beaches on St Barthélémy are known as "Anse de..." etc. ) of which 15 are considered suitable for swimming. They are categorized and divided into two groups, the leeward side (calm waters protected by the island itself) and windward side (some of which are protected by hills and reefs). The windward beaches are popular for windsurfing. The beach of St Jean is suitable for water sports and facilities have been created for that purpose. The long beach at Lorient has shade and is a quiet beach as compared to St. Jean.
