What January feels like

January is Sardinia at its quietest and most local. The light is low and clear, the beaches belong to dog walkers, and inland the bars fill with talk instead of tourists. Mid-month the mountain villages light the bonfires of Sant'Antonio Abate, the first stirring of carnival, and by late January the first almond blossom appears in sheltered corners. It is a month for slow food, museums and bright, blustery coastal walks. Around Cagliari and the Campidano the capital anchors everything, with Poetto's long beach and the south coast an easy reach away.
