Calanque de Port-Pin
To be fair, it is quite a challenge to find a secluded beach in the Mediterranean during the high season. The best bet is to head for the Calanques, as the beautiful coves carved into the craggy coast are called. Head for those spots that are not easily accessible by car such as the Calanque de Port-Pin located near La Ciotat. It is accessible either by boat or about 30 minutes on foot via the walking trail from the Calanque de Port-Miou. In the off-season, there is an accessible parking lot in the Gardiole Forest and then a footpath that descends toward the sea. From Gardiole, it takes about an hour and a half to get to the water so plan to return while there is still daylight.
