Costa Diadema, launched in 2014, is built for relaxation and fun with lots of on board activities, lively bars, gourmet restaurants and the spa area.

Among the special features not to be missed: an entire deck dedicated to children, complete with a castle and pirate galleon, plus the terrace on deck 5 for strolling and enjoying an cocktail at sunset: a real treat for vacationing in perfect Italian style. The cabins aboard our flagship are elegant, well-appointed and spacious for up to five guests. At any time of the day or night you'll be spoilt for choice on what to do: sports, games, a large three-story theater where international artists, and you too can be in the show with Tu sì que Vales... and then the Aperol Spritz Bar for a cocktail before dancing the night away at the disco, a games room for returning to your childhood, and a real German pub. We look forward to welcoming you on board.
