The National Park has marked out three theme trails around the island. The first one, the botanical trail, lets you discover all the richness of the Port Cros vegetation. This walk runs along the coast and gives you beautiful views of the sea, then comes back to the village through the island's interior.
The second, the "history trail", climbs the hills' summits and leads to the island's five forts (Forts du Moulin, de l'Estissac, de l'Eminence, de Port Man and de la Vigie). The hike takes approximately one day : be careful not to miss the last boat back in the vening !

The third trail, the most original, is one that introduces you to to the marine environment. For Port Cros is the first national sea park in Europe and the Mediterranean : its sea bottom is preserved ; the undersea fauna and flora is exceptional. Experienced divers love exploring, for example, the surroundings of the Gabinière rock, as there are many moray eels, groupers and barracudas.

From Mont Vinaigre - 196 meters high, the island's peak - to its undersea oasis carpeted with Posidonias, Port Cros is a true gift to nature lovers…

But for beginners, the undersea trail between the La Palud beach and the Ilot du Rascas provides an excellent glimpse of the sea floor's beauty. Equipped with a mask, a snorkel and a pair of flippers, accompanied or not by a park guide, all you have to do is follow the ten numbered observation markers, easily seen from the surface. A plastic-coated leaflet edited by the Parc lets you read, while you're swimming, commentaries on the observed fauna and flora.
