What December feels like
December is crisp, bright and gently festive. Christmas markets and nativity scenes appear in the towns, the Gennargentu often takes a dusting of snow, and clear days deliver some of the year's sharpest coastal light. The sea is for looking at, the table is for sitting at, and the island feels entirely its own. A fine month for city breaks in Cagliari or Alghero. In Gallura that means granite coves and the Costa Smeralda, with La Maddalena's islands offshore and the Vermentino hills behind.
