Princess Cruises is adding four 17-day Antarctica voyages from Buenos Aires to its 2024-25 South America itineraries.
Sapphire Princess and Majestic Princess will be deployed in the region to run 15 departures on 11 itineraries.
The vessels will cover 25 destinations in 14 countries during the season, including the Falkland Islands, Elephant Island, Antarctic Sound and Gerlache Strait.
The line claimed: “As the top-rated large ship cruise line in the region, only Princess offers guests an up-close look at the wonders of the white continent while enjoying large ship comfort and small ship personalisation at a fraction of the price of explorer ships.

“Princess is a member of the prestigious International Association of Antarctica Tour Operators, placing a priority on environmental responsibility and safe travel at the forefront of every voyage.
“As a symbol of large ship exploration, Sapphire Princess will also embark on a series of South American itineraries, joined by Majestic Princess to offer an enchanting fusion of exotic cultures and landscapes combined with exciting cruise tours.”
Among the sailings is a 51-day cruise between Los Angeles and Fort Lauderdale, with overnight stays in Lima, Buenos Aires and Rio de Janeiro.
Princess Cruises president John Padgett said: “No other large ship cruise line sails Antarctica like Princess.
“Our master navigators, unique local relationships and outstanding amenities make accessing these exotic destinations not only immersive but amazingly comfortable.”
