Župa Dubrovačka stretches between Dubrovnik, the old Ragusa in the west and Cavtat, the ancient Epidaurus in the east, between the settlements of Dubac and Plat. The three islands Supetar, Mrkan and Bobara anchored right in front of the bay protect it from the open sea and from the north the hilly slopes of the Upper Župa. Tourist resorts are clustered along the coast.
