The Sinzias Cove lies in the coastal area of Castiadas, to the south-east of Sardinia, in the province of Sud-Sardegna.
The cove stretches for around2 kilometres, north of the promontory of Punta de is Cappuccinus.
In the middle of the beach is the mouth of the Rio di Laccus, which tends to dry up during the warmer months.
The shoreline has fine-grain clear sand, bordered to the north and south by granite rock reefs.
There is a small dune system at the highest point of the beach, mainly colonised by typical herbaceous species found in this area.
Behind the beach, in the central-southern part, is a small forest of eucalyptus growing alongside shrub with junipers, mastic trees, wild olive and pines.
The sea at Cala Sinzias is clear and transparent, maintaining its naturalness, so much so that it was flagged by Legambiente’s Goletta Verde as one of the purest in Sardinia.
The underwater bar system of the submerged part of the beach creates alternations of shallow or deep seabeds, depending on the part of the beach.
Since the 1980’s Cala Sinzias, has been a tourist destination with an area equipped for campers and two well-known camping villages overlooking the beach.
The beach provides full services: parking, beach resorts with swimming facilities, kiosks-bars and restaurants. The beach is also accessible to differently abled people.
