The Massif des Calanques (French pronunciation: [masif de kalɑ̃k]) is a wild and rugged terrain stretching from the ninth arrondissement of Marseille to the east towards Cassis, spanning 20 km in length and 4 km in width along the coast. Its highest peak is Mont Puget at 565m. The area has been protected by a national park since 2012.[1]
The massif is characterized by steep cliffs of limestone (Urgonian and dolomite) in the western part, and of a combination of limestone, sandstone and puddingstone east of Cassis.[2]
