The marine protected area of Capo Caccia – Isola Piana has, at the base of the cliff, a spectacular sea cave, the Grotta di Nettuno, with amazing stalactites and stalagmites.
Make sure you pay a visit to the MareNostrum Aquarium, with both sea and freshwater fishes, and to the Coral Museum.
Alghero, a lively town year round, truly lets its hair down for the New Year celebrations: throughout December and well into January, the Cap d'Any de l'Alguer attracts people from all over Sardinia – and beyond – with a calendar packed with shows and concerts.
But the truest Alghero is perhaps to be seen during Easter Week, when the whole town joins in the fascinating rituals harking back to its Spanish traditions.
