The cove takes its Italian name from a saying of a fisherman from Ponza, who sheltered his freshly caught fish in a small cave near the beach where he moored. The fisherman did not know, however, that the famous monk seal was present throughout the Costa Baunese, coming out of the water and eating the fish hidden in the cave. The fisherman, who did not know the existence of the seal, exclaimed “Acca cestà Mariolu” (in Italian “there is some thief here”) and since then this exclamation gave the name to this cove.
The original and correct toponym is Is Puliges de Nie (or Ispuligedenie), which means ‘the snow fleas’ and refers to the numerous small white pebbles that form the beach of the cove. Another possible and probably more correct local toponym is Ispuligiada ‘e nie which means’ splash of snow’ which is the image that best describes the beach.
The beach, about 200 m wide, represents the mouth of a small winter stream (codula in Sardinian) that descends from the nearby mountains of the Golgo plateau. It is composed of very white pebbles that stand out with the color of the water making it particularly clear and transparent. The beach is well served, in the summer, by a small fleet of boats that transport visitors through all the coves of the Gulf of Orosei.
