What May feels like

May might be the connoisseur's month. The island is green, the days are long and warm, and two of Sardinia's great festivals arrive: Cagliari's Sant'Efisio procession on 1 May and Sassari's Cavalcata Sarda. Brave swimmers open their season in the shallower bays while walkers get the last comfortable big-mountain days before summer. Beaches are gloriously underpopulated. Around Cagliari and the Campidano the capital anchors everything, with Poetto's long beach and the south coast an easy reach away.
