Why sail this route

You unpack once and let the ship do the travelling: 3 countries over 4 nights, starting in Buenos Aires and finishing in Santos (Sao Paulo), with a new port waiting most mornings instead of airports and hotel check-ins.

The pacing runs to 4 port days and 1 day at sea — time to enjoy the ship between stops.

About This Cruise

The 4 Night South America from Buenos Aires is a 4-night one-way itinerary aboard Costa Diadema. You board in Buenos Aires and disembark in Santos (Sao Paulo), calling at 4 ports across 3 countries along the way.

In sequence the voyage takes in Argentina (Buenos Aires), Uruguay (Montevideo) and Brazil (Itajai, Santos).

As a one-way sailing you'll fly into Buenos Aires and home from Santos (Sao Paulo), so it's worth checking the two gateways before you book. Longer hops are crossed on the 1 day at sea, keeping daylight hours for the ports.
