South America is one of the most rewarding long-haul cruise destinations for UK travellers, offering everything from the wildlife-rich Galápagos Islands to the dramatic fjords of Chilean Patagonia. Sailings typically depart from ports such as Buenos Aires, Santiago (San Antonio), or Barbados, making them straightforward to reach with a transatlantic flight. We currently list 16 live South America sailings, giving UK cruisers a solid range of itineraries and departure dates to choose from.
When Is the Best Time to Cruise South America?
The best months to cruise South America are November through to March, which corresponds to the Southern Hemisphere's spring and summer. During this period, temperatures along the east and west coasts are warm and generally settled, making it ideal for exploring cities like Buenos Aires and Lima. If Patagonia or Cape Horn is on your itinerary, this same window offers the most manageable weather, though conditions in the far south can still be changeable. UK travellers benefit from the fact that this season falls over the British winter, making it a popular escape from the cold.
Which Cruise Lines Sail to South America?
A range of cruise lines operate South American itineraries, from mainstream operators such as MSC Cruises and Holland America Line to more premium and expedition-focused brands. Expedition lines are particularly well represented on routes that include the Galápagos Islands or Antarctic approaches, where smaller ships can access more remote anchorages. Mainstream lines tend to focus on the classic South American circuit, combining ports in Argentina, Uruguay, Brazil, and Chile. It is worth comparing what each line includes in the fare, as some bundle excursions and flights while others price these separately.
Key Ports and What to Expect
Buenos Aires is the most common embarkation point and rewards an early arrival, with its European-influenced architecture, world-class steak restaurants, and vibrant tango culture. Montevideo in Uruguay is a relaxed, walkable city often included as a day call, offering colonial streets and a long coastal promelade. On the Pacific side, Valparaíso serves as the port for Santiago and is a colourful, hilly city of street art and funicular railways worth exploring in its own right. Further south, the Chilean fjords and ports such as Puerto Montt or Punta Arenas offer dramatic Andean scenery and access to glaciers.
Typical Itinerary Lengths and Styles
South American cruises tend to run longer than typical European itineraries, with most sailings lasting between 14 and 21 nights to do the continent justice. Shorter itineraries of around 10 to 14 nights are available and usually focus on one coast, such as a Brazil and Argentina circuit or a Pacific route between Colombia and Chile. Grand voyages that circumnavigate the continent, rounding Cape Horn, are also available and can run to 30 nights or more. UK travellers should factor in flight time to the embarkation port, which typically adds a day at each end of the trip.
Finding Good Value on a South America Cruise
Booking early tends to offer the best cabin selection and introductory pricing, particularly for the peak November to March season when demand from both hemispheres is high. Repositioning cruises, where a ship moves between regions at the start or end of a season, can offer significantly lower per-night costs, though itineraries may include more sea days. Travelling as a couple or group and being flexible on cabin grade can also reduce costs considerably. Comparing what is included in the headline fare — such as flights, gratuities, drinks packages, and excursions — is essential, as the all-in cost can vary widely between lines.
