Posada is located on the east coast of Sardinia just 3km from the sea with the fine sandy beaches. To the south you meet the Gennargentu mountain and the many hidden lagoons and caves along the coast, but you come north to the beautiful sandy beaches, including La Cinta at San Teodoro. The town has a lovely hilltop medieval centre including a 13th Century Castle Castello della Fava with a fine panoramic view.
