21 Night Cruise from Genoa

About this cruise

Somewhere around day five the ship stops being transport and starts being home. This 21-night sailing from Genoa on November 2, 2026 visits Barcelona, Málaga and Cádiz, with additional stops along the Western Mediterranean. The sailing ends in Santos. That gives you 11 days in port and 10 at sea, enough of each to find a rhythm. The Western Mediterranean route takes in Spain, Portugal, Cape Verde and Brazil, 4 countries, and the differences show up in the food, the architecture, and the mood. Most ports give you about 9 hours, so you can do more than just tick off the main sights. As for the ship itself, Costa Diadema: 3,724 guests, 14 decks. Entertainment, dining, and enough space that it never feels cramped. By night three you start recognising faces; by night ten you're swapping numbers. That's the magic of a longer sailing. If you like having options (restaurants, bars, activities, entertainment), a big ship delivers that. Being shoulder season helps: golden light, comfortable weather, and shorter queues at the popular spots. If you've been thinking about a cruise, this 21-night sailing is a strong place to start.
