One of three Costa Cruises ships in South America this season, the Costa Diadema recently offered its first-ever cruise to Argentina and Uruguay.

The 3,700-guest ship debuted in the two countries as part of a seven-night itinerary that includes visits to Buenos Aires and Montevideo, as well as the Brazilian ports of Santos and Itajaí.

Sailing from multiple homeports, the cruise will be offered through early April and also includes three days at sea.

“We had great demand for this itinerary in the 2023-24 season, so we decided to increase our offering in this region,” said Renê Hermann, Costa’s Brazil president.

The Costa Diadema takes over the itinerary from the smaller Costa Favolosa, which had been sailing to Argentina and Uruguay for the past two summer seasons.

While most of the ship’s capacity will be allocated to the Brazilian market, passengers will also be able to embark in Argentina.

“We’ve also seen significant demand in the country, and we’ll have guests embarking there too,” Hermann told Cruise Industry News.

In addition to the Costa Diadema, Costa’s 2024-25 deployment in South America also includes the Costa Favolosa and the Costa Pacifica.

The Costa Pacifica opened the company’s season in South America after arriving in Brazil in late November.

Sailing from Santos and Rio de Janeiro, the 2009-built vessel will be fully dedicated to the Brazilian market through late March.

Offering longer itineraries in the region, the Costa Favolosa is also offering cruises to Brazil, Argentina and Uruguay.

The vessel’s eight- to nine-night itineraries sail from Rio de Janeiro, Buenos Aires and Montevideo and visit destinations that include Punta del Este, Balneário Camboriú and Ilhabela.

After completing its schedule of seven-night cruises in the region, the Costa Diadema is scheduled to offer short cruises from Santos before returning to Europe in late April.
