Like Villeneuve-Loubet Plage, Cagnes-sur-Mer’s interior is uninspiring, just a collection of dull apartment blocks, but it’s very close to Nice airport, on the useful coast road (that is frequently choked in summertime), near Cap 3000 shopping centre and has frequent music/firework festivals during the summertime along the shore road.
. . . but beach freaks will be more interested in a good selection of marine activities.
