On the west coast of Sardinia, Porto Conte Bay (a few miles from Aghero) stops at the Capo Caccia, a sharp cape whose base houses the amazing Cave of Neptune. Its rooms are adorned with splendid limestone concretions. You can enter the cave by descending the stairs carved into the cliff, although it might take you a while as there are 654 steps in total, or alternatively they are also accesible by boat from Alghero.
The towers of the Sardinian coast, still visible today, were the island's main defense system up to the middle of the 19th century.© Jordi Ferre / age fotostock
