Straits of Florida
Havana lies on the northern coast of Cuba along the Straits of Florida, south of the Florida Keys, where the Gulf of Mexico joins the Atlantic Ocean. The city extends mostly westward and southward from the bay, which is entered through a narrow inlet and which divides into three main harbors: Marimelena, Guanabacoa, and Atarés. The sluggish Almendares River traverses the city from south to north, entering the Straits of Florida a few miles west of the bay.
