The creek of Port-Miou is the last of the twenty-seven creeks of the Massif des Calanques towards Cassis from Marseille. It is also the longest among them, extending inland for 0.6 mi (1.6 km). Made up of limestone rocks, the creeks encompass the massifs of Marseilleveyre (1417 ft/432 m) and Puget (1847 ft/563 m), essentially located on the municipal territory of Marseille except for the creek of Port-Miou, part of the municipality of Cassis.
