In 1923, the Comité de défense des Calanques was established with the aim of preventing industrial development at En-Vau. In 1999, the groupement d'intérêt public (GIP) des Calanques was founded to prepare the creation of a national park. Eleven years later, the GIP presented its first draft for a national park; the third draft was approved in 2011. On 18 April 2012, Prime Minister François Fillon signed the decree establishing Calanques National Park.
