The area of the Bulgarian Black Sea Coast is situated along the entire eastern border of this country and the adjoining aquatorium. Beginning at cape Sivriburun at the border with Romania, it ends at the estuary of the Rezovska River at the border with Turkey. Though only 387 km long, it is unique due to the diversity of its flora and fauna, architecture and the availability of facilities for leisure time activities such as sports and entertainments. Conventionally, it is divided into a northern part (to the north of Cape Emine) and a southern part (to the south of Cape Emine). The southern seaside is known for its wide and long beaches, while in the north there are sandy beaches alternating with rocky landscapes.
