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. Around Cagliari and the Campidano the capital anchors everything, with Poetto's long beach and the south coast an easy reach away.
