Port-Cros is one of the three islands of Hyères, coastal archipelago in the Mediterrenean Sea, off the bay of Hyères. 4.5 km long and 2 km wide, its highest point is at 199 m above sea level, summit of the archipelago. The presence of sources explains its rich vegetation.
In the early 1960s, its owner gave it to the State against the promise of making it a national park, a reserve of fauna and flora. The National Park of Port-Cros was created December 14,1963. This national, land and marine, park is the only one of which the State is almost entirely owner.
