Earth : Europe : Italy : Southern Italy : Basilicata : Metaponto
There are old ruins in Metaponte. But the main attraction is the 1 km stretch of perfect beach with white powdery sand.
The beach can be crowded with Italians, but once you get into the water there is plenty of room. The water gets deep only after you get 30-50m out and most Italians stay on the beach. You can rent parasols and beds, but there are many free strips.
The sheds right on the beach sells beer, limocelli for E2.
