Caves of Capo Caccia
The Capo Caccia headland is full of caves: underwater lies the Grotta di Nereo, the largest sea cave in the Mediterranean, with red coral and lobsters.
The story
Alghero's red coral, fished for centuries, gave this stretch of coast its name, the Riviera del Corallo. Neptune's Grotto, visited from land by going down the Cabirol staircase, has more than 600 steps cut into the cliff.
Why go
Because it is one of the most famous diving areas in Europe, with caves for every level.
Which wind
Good with Levante, Scirocco
Avoid with Maestrale (mistral)
