Enjoy a fix of vitamin D at Plage du Bestouan. After you've topped up your tan, hang around and watch the sky transform with colors as the sun fades away.
When you've spent some time at this Cassis stretch of coastline, why not make your way to Calanque Sormiou, Calanque de Port Miou, and La Ciotat Beach? They're near Plage du Bestouan and also popular with many travelers.
