The state is the sole land owner on the island, which is a natural protected area.

The park's boundaries were extended in 2012 to encompass most of Porquerolles.

Until 2012, about 1,000 hectares of land on the island of Porquerolles had since 1971 been under the national park's administration (Conservatoire Botanique National Méditerranéen de Porquerolles).

There are strict behaviour rules for the few inhabitants as well as daily tourists there.

Sea bathing is only permitted on three beaches and smoking or taking dogs can result in an extensive fine.
