6 nights, Lisbon to Southampton

Six nights, five port calls, one direction: Lisbon to Southampton, tracing the Atlantic edge of Iberia and France before crossing the Channel. The shape is brisk and city-forward. You start in the medieval tangle of Alfama, with the terminal at the foot of the old quarter and the Baixa a short walk the other way. Then it climbs north: Leixões for Porto's granite riverfront and port-wine lodges across the Douro, La Coruña for a walkable Galician old town around Plaza de Maria Pita and serious octopus, Bilbao for Gehry's titanium Guggenheim, and Pauillac, where the ship ties up at the town quay in the heart of the Medoc, gateway to three of the five Premier Cru estates.

This itinerary rewards travelers who like a steady cadence of compact, walkable port cities and don't mind that two calls demand planning. Bilbao docks in Getxo, well down the estuary from the city, and Pauillac's chateaux sit inland from the quay, so both reward a plan made before you arrive. Southampton is a turnaround gateway, not a sightseeing prize, so don't book this for the last stop. If you want long sea days or a single-country deep dive, pick a different route. If you want wine country and four distinct Atlantic cities at a real pace, this is a strong one.

EXPLORA IV is all-suite and all-oceanfront.
