10 days, round-trip Western Mediterranean from Barcelona

About this cruise

10 nights, 7 ports, all from Barcelona on October 9, 2026. The route visits Tangier, Casablanca and Cádiz, with additional stops along the Western Mediterranean and the whole thing just flows. The itinerary clusters several port calls together. Fast-paced for a few days, then the sea days hit and you can catch your breath. The Western Mediterranean route takes in Morocco, Spain, United Kingdom, France and Italy, 5 countries, and the differences show up in the food, the architecture, and the mood. You get around 10 hours in each port, which is enough for an excursion, lunch, and some wandering around on your own. When you're not ashore, Costa Diadema holds 3,724 guests across 14 decks. It's a big ship, with plenty to keep you busy. One of the underrated parts of a longer cruise: you actually get to know people. The couple from dinner, the group at trivia, the bartender who remembers your drink. If you like having options (restaurants, bars, activities, entertainment), a big ship delivers that. An October sailing dodges the peak crowds while the weather is still cooperating. Well timed. If you've been thinking about a cruise, this 10-night sailing is a strong place to start.
