You can zoom in to look at the ones nearest the areas which interest you. In addition to telling you if it's sandy or rocky or both, it tells you whether there's a marina, boats etc.

Tiny Liguria has the highest number of them. However, be advised that they're usually not large and parts can be rocky. For broader, sandy beaches, neighboring Toscana has Marina di Massa, or Forte de Marmi, for example.

Among those listed:

Lerici has quite a few beaches on the list. This is just one of them.

Blue flag beach at Levanto. It's much better than the one at Monterosso in the Cinque Terre. In fact, I often recommend tourists stay here in preference to staying in the Cinque Terre proper. The trails connect, and it's not quite so claustrophobic in the summer.

Along the Amalfi coast, the beaches at Positano are clean and beautiful, but Positano makes me feel claustrophobic, especially in summer when all I hear in the tiny streets are American voices. So, if it's high summer, I like Verano beach near Sorrento or the beaches in Massa Lubrense. There are sandy beaches, but I love the rocky coves. What they do is flatten stones or create concrete platforms for the sunbeds. No sand in your bathing suit, but it's still two steps to the water, and you still get the views and the smells. It's just heaven. We do the same thing along the coast in Liguria, in Santa Margherita Ligure, for example. I know most Americans and northern Europeans tend to go for the wide sandy beaches, but not me.
