14 days, one-way from San Antonio to Buenos Aires

About this cruise

Clear the calendar from December 8, 2026. This one's 14 nights from San Antonio, and the route visits Puerto Montt, Puerto Chacabuco, Punta Arenas, Ushuaia, Puerto Madryn and Buenos Aires. By the time you're a week in, you'll have completely stopped checking your phone. The trip wraps in Buenos Aires, so you won't retrace your steps. The final stretch is open ocean, which gives you time to process everything you've seen and use the ship one last time. Tango, rainforest, Patagonian ice. South America covers a lot of ground. You get around 10 hours in each port, which is enough for an excursion, lunch, and some wandering around on your own. When you're not ashore, Costa Serena holds 3,014 guests across 13 decks. It's a big ship, with plenty to keep you busy. One of the underrated parts of a longer cruise: you actually get to know people. The couple from dinner, the group at trivia, the bartender who remembers your drink. While everyone else deals with the December cold, you'll be somewhere warmer. And floating. Whether you've cruised before or not, this 14-night itinerary is a genuinely good one.
