11 Night Cruise from Barcelona

About this cruise

11 nights starts to feel like a proper adventure. You leave Barcelona on September 28, 2026 and the route takes you through Cádiz, Lisbon and Gibraltar, with additional stops along the Western Mediterranean at a pace where there's never any need to rush. A few ports come in quick succession, which is great for sightseeing but means you'll appreciate the sea days when they arrive. The route threads through 5 countries along the Western Mediterranean coast: Spain, Portugal, United Kingdom, France and Italy. Lisbon alone is worth the trip, Seven hills of fado, pastéis, and golden light. Around 9 hours per port on average, which is generous enough to go beyond the obvious. At 132,500 gross tons, Costa Diadema is big enough that you can find a quiet corner or a crowd, depending on your mood. There are enough performances, events, and social mixers on a cruise this length that you couldn't do them all if you tried. And that's a good problem. Barcelona itself is worth spending some time in. Don't just treat it as a departure point. The autumn timing is underrated too. Good weather, calmer seas, and a more relaxed ship. Worth booking. That's the short version.
