About This Cruise
The 21 Night Ocean Cruises from Marseilles is a 21-night one-way itinerary aboard Costa Diadema. You board in Marseille and disembark in Itajai, calling at 14 ports across 7 countries along the way.
In sequence the voyage takes in France (Marseille), Italy (Savona), Spain (Barcelona, Malaga, Cadiz), Portugal (Lisbon), Canary Islands (Gran Canaria, Tenerife), Cape Verde (Mindelo) and 1 more.
As a one-way sailing you'll fly into Marseille and home from Itajai, so it's worth checking the two gateways before you book.
