About This Cruise
The 18 Night Antarctic Encounter Buenos Aires To Lima (Callao) is a 18-night one-way itinerary aboard Regent Seven Seas Mariner. You board in Buenos Aires and disembark in San Antonio, calling at 6 ports across 3 countries along the way.
In sequence the voyage takes in Argentina (Buenos Aires), Falkland Islands (Port Stanley), Argentina (Ushuaia) and Chile (Punta Arenas, Puerto Montt, San Antonio).
As a one-way sailing you'll fly into Buenos Aires and home from San Antonio, so it's worth checking the two gateways before you book. Longer hops are crossed on the 9 days at sea, keeping daylight hours for the ports. Sailing dates, cabin availability and fares vary by season — use Check Dates & Prices for live pricing, or call our team to talk through the options.
