Prices and availability are subject to change; final price confirmed at booking.
Ponant
Ponant offers South America expedition voyages from $5,000, with itineraries starting from 19 nights. The line is known for operating small, elegantly appointed expedition vessels that combine a French-influenced hospitality style with access to remote destinations across Patagonia and the Antarctic Peninsula.

Antarctica21
Antarctica21 offers South America expedition departures from $5,000, with itineraries starting from 8 nights. The operator is notable for its fly-cruise format, which typically combines flights into the region with ship-based exploration, reducing overall travel time at sea.

Quark Expeditions
Quark Expeditions offers South America expedition voyages from $7,000, with itineraries starting from 13 nights. The operator runs a varied fleet that includes ice-strengthened vessels, and its programs span destinations from the Antarctic Peninsula to the sub-Antarctic islands. Itinerary lengths fall in a mid-range that balances depth of exploration with overall trip duration.
Best fit: Well-suited for expedition-minded travelers looking for a mid-length voyage with a strong focus on polar and sub-Antarctic environments.
Polar Latitudes
Polar Latitudes offers South America expedition voyages from $11,000, with itineraries starting from 9 nights. The line operates smaller vessels, which can allow for a more intimate group experience and greater flexibility in accessing remote landing sites. Its programs focus on the Antarctic Peninsula and surrounding waters.
Best fit: Well-suited for travelers who prioritize small-group dynamics and a more personalized expedition experience in Antarctic waters.
UnCruise Adventures
UnCruise Adventures offers South America expedition voyages from $11,000, with itineraries starting from 7 nights. The operator is known for its active, adventure-forward approach, with programs that emphasize kayaking, hiking, and other shore-based activities alongside ship-based exploration. Shorter voyage lengths offer a more compact expedition format.
Best fit: Well-suited for active travelers who want a shorter but activity-rich expedition, with an emphasis on hands-on outdoor experiences.
These five operators reflect the breadth of options available for South America expedition cruising. Starting prices range from $5,000 to $11,000, and voyage lengths span from 7 nights to 19 nights, offering meaningful variation in both budget and time commitment. Itinerary length, onboard style, activity focus, and departure format (traditional embarkation versus fly-cruise) are among the key factors that differentiate these lines. No single operator is the definitive choice for all travelers; the most suitable option will depend on individual priorities around trip duration, activity level, group size preference, and overall travel style.
