40 days, one-way from Sydney to Buenos Aires
About this cruise
A 40-night sailing gives you something shorter trips can't: the feeling that you're not just visiting places but actually living somewhere else for a while. This one leaves Sydney on November 12, 2026 and visits Noumea, Lifou Island and Suva, with additional stops along the South America. Disembarkation is in Buenos Aires. You ease into this one, with a few sea days up front to find your rhythm before the 15 port calls start. The route threads through 8 countries along the South America coast: New Caledonia, Fiji, Tonga, Cook Islands, French Polynesia, United Kingdom, Chile and Argentina. If one port sticks with you, it'll probably be San Antonio, Chile's Pacific gateway to vineyards and valleys. 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. There are enough performances, events, and social mixers on a cruise this length that you couldn't do them all if you tried. And that's a good problem. Sydney itself is worth spending some time in. Don't just treat it as a departure point. The autumn timing is underrated too. Good weather, calmer seas, and a more relaxed ship. It's the kind of trip you actually remember afterwards.
