Costa Cruises Launches 2026-2027 South America Season with New Itineraries and Revitalized Ships for Unforgettable Voyages

Published on December 27, 2025

Costa Cruises has launched its 2026-2027 South America season, introducing a series of exciting new itineraries aboard revitalized ships, the Costa Diadema and Costa Serena. These ships will offer unforgettable voyages to some of South America’s most vibrant destinations, including Brazil, Argentina, and Uruguay. With the Costa Serena‘s recent enhancements and a range of both short and long itineraries, this season promises guests an extraordinary cruising experience, from quick getaways to immersive regional explorations, ensuring a memorable journey for every traveler.

The Costa Diadema, one of Costa’s flagship vessels, will kick off the season on November 26, 2026. This ship will offer short, three- and four-night cruises departing from Santos and Itajaí in Brazil, heading to the scenic Ilhabela island. Ilhabela, renowned for its lush tropical landscapes and pristine beaches, is the perfect destination for a quick getaway, offering guests the chance to relax and explore the natural beauty of this Brazilian gem.

As the season progresses, the Costa Diadema will expand its itinerary to longer seven-night cruises starting December 20, 2026. These sailings will depart from Santos and Itajaí, making stops in Buenos Aires, Argentina, and Montevideo, Uruguay. Buenos Aires, with its European-inspired architecture, tango culture, and vibrant city life, presents a thrilling urban experience. Montevideo, known for its relaxed coastal atmosphere and historic charm, offers visitors a more tranquil alternative, making the seven-night journey a perfect way to experience both sides of the region.

In addition to the Costa Diadema, the Costa Serena will make its return to South America after more than a decade. The Costa Serena is set to start its season on December 22, 2026, following a 65-night voyage from Tokyo to Buenos Aires. This marks the ship’s first deployment in the region since 2007, and it promises an exciting lineup of cruises ranging from three to nine nights. Departing from Buenos Aires, Montevideo, and Rio de Janeiro, the Costa Serena will visit a diverse range of destinations, including Punta del Este, Ilhabela, and Balneário Camboriú.

With the Costa Serena’s return, passengers will be treated to newly enhanced features, thanks to a comprehensive revitalization completed earlier this year in Asia. The ship now boasts upgraded interiors, improved amenities, and new services aimed at enhancing the overall guest experience. These upgrades ensure that the Costa Serena is ready to offer a modern and luxurious cruise experience on its return to the South American market.

The Costa Serena’s itineraries will visit some of South America’s most iconic spots, such as Punta del Este, Uruguay’s top beach destination, as well as Ilhabela and Balneário Camboriú in Brazil. These ports offer a blend of scenic beauty, cultural exploration, and leisure, providing a balanced and diverse cruising experience for guests.

At the conclusion of their South American season, both the Costa Diadema and Costa Serena will offer repositioning cruises to Europe. On April 5, 2027, the Costa Diadema will embark on a 26-night trans-Atlantic journey from Santos to Kiel, Germany. This repositioning voyage will offer guests an extended cruise experience, with plenty of time to enjoy the ship’s luxurious amenities and services.

Costa Cruises’ 2026-2027 South America season offers an exciting range of options for all types of travelers. Whether seeking a quick getaway with a mini-cruise or a longer, immersive experience, Costa’s variety of itineraries caters to every preference. Passengers will have the opportunity to explore some of the most vibrant and beautiful cities in South America, from the lively streets of Buenos Aires to the serene beaches of Ilhabela.
