10 days, round-trip Western Mediterranean from Barcelona

About this cruise

A week or so at sea, a few great ports, and nothing to organise once you're on board. This 10-night sailing from Barcelona on October 9, 2026 visits Tangier, Casablanca and Cádiz, with additional stops along the Western Mediterranean. Expect a run of consecutive ports, 7 stops total, with the busiest days packed close together. The sea days around them feel earned. 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. Don't rush through Gibraltar, which is known as A British rock at the mouth of the Mediterranean. Roughly 10 hours ashore per stop. No need to rush. Costa Diadema carries up to 3,724 guests over 14 decks. Multiple pools, a theatre, and more restaurants than you'll get through. The shows alone are worth the extra nights. You'll catch comedy, music, theatre, and themed evenings you'd miss on a shorter trip. Families and groups will find plenty to do: waterslides, shows, multiple pools, and something for every age. If you can, add a night in Barcelona before boarding. It's a good city to wander. And October is a good call. Still warm, less crowded, and usually cheaper too. All told, 7 ports across 10 nights covers a lot.
