What September feels like

September is the locals' favourite, and ours. The crowds thin within a fortnight, the sea stays warm well into October, and the light turns soft and amber. Vendemmia, the grape harvest, animates the wine country, restaurants have time to talk again, and you can hike in the morning and swim in the afternoon. If you can travel in September, travel in September. In the Sulcis-Iglesiente that means mining ghost towns, the dunes of Piscinas and the islands of Carloforte and Sant'Antioco.
