9 days, round-trip South America from Buenos Aires

About this cruise

No complicated itinerary, no back-to-back transfers, just the ports, the ship, and the sea in between. This 9-night sailing from Buenos Aires on December 27, 2026 visits Montevideo, Balneario Camboriu, Ilha Grande, Rio de Janeiro and Ilhabela. You do all the exploring first, then the last few days are at sea. It's like a built-in wind-down. Tango, rainforest, Patagonian ice. South America covers a lot of ground. People come back from this cruise talking about Balneario Camboriu: Brazil's Copacabana of the south. Around 9 hours per port on average, which is generous enough to go beyond the obvious. At 114,147 gross tons, Costa Serena is big enough that you can find a quiet corner or a crowd, depending on your mood. Buenos Aires itself is worth spending some time in. Don't just treat it as a departure point. A December sailing is basically an excuse to chase the sun for a week or two. 5 ports, 2 countries, one suitcase. That's the appeal.
