What April feels like

April is prime shoulder season: warm enough for lunch outside, cool enough to hike all day. This is peak wildflower month, with asphodel and orchids along every trail, and Holy Week brings haunting processions to Castelsardo, Alghero and the interior. The sea still bites, but everything else, from archaeology to agriturismo tables, is at its absolute best. In the Oristanese and Sinis it is lagoons and flamingos, quartz-sand beaches and the Phoenician ruins of Tharros.
