About Alghero

Alghero is a Catalan-flavored fortress town on Sardinia's northwest coast—coral jewelry shops, Aragonese walls, and a port where lobster is the local religion. May to June and September to October deliver ideal beach weather for Capo Caccia boat trips to Neptune's Grotto and afternoons on Maria Pia or Bombarde sands without August's packed flights. July and August are hot and fully booked; reserve grotto tours and rental cars early. Winter stays mild and uncrowded for walled-lane walks, though sea conditions often cancel boat excursions.
