South of Salerno, most famous for its ancient Greek cities of Paestum and Velia, Cilento National Park is an UNESCO World Heritage Site and birthplace of the Mediterranean diet. Cilento National Park has gained immense popularity as travelers reveal its unspoiled treasures and natural wonders. Admire centuries old olive trees, ride in a boat or scuba-dive through astonishing caves, dine in a medieval castle, swim in the crystalline sea at one of many pristine beaches and explore rustic towns where the magic of old traditions, festivals, processions and rituals have been well-preserved for centuries.
