The Luberon (French pronunciation: ​[lyb.ʁɔ̃]; Provençal Occitan: Leberon in classical norm or Leberoun in Mistralian norm) is a massif in central Provence in Southern France. It has a maximum elevation of 1,256 metres (4,121 ft) and an area of about 600 square kilometres (230 sq mi). It is composed of three mountain ranges (from west to east): the Lesser Luberon (Petit Luberon), the Greater Luberon (Grand Luberon) and the Eastern Luberon (Luberon oriental). The valleys north and south of them contain a number of towns and villages as well as agricultural land; the northern part is marked by the Calavon, while the southern part is characterised by the Durance.
