Costa Diadema

The Costa Diadema, often referred to as the "Queen of the Mediterranean," is a vibrant ship known for its energetic "Italy at Sea" atmosphere. Depending on the season, she utilizes major homeports such as Savona, Barcelona, Kiel, Copenhagen, and Santos (Brazil). Her diverse itineraries reflect this global footprint, offering everything from immersive Western Mediterranean sailings and South American escapes to summer voyages exploring the breathtaking Norwegian Fjords and Northern Europe. While onboard, guests can enjoy a variety of standout amenities, highlighted by a stunning 500-meter-long outdoor promenade on Deck 5 that gives the ship a seaside resort feel. Other notable features include an expansive, multi-level Samsara Spa for ultimate relaxation, multiple pools with retractable roofs for all-weather swimming, and an immersive 4D cinema for high-tech entertainment.
