Travelers should fly to Ushuaia, Argentina and board an expedition ship to Antarctica. Flights to Ushuaia are available from Buenos Aires and other major cities in South America. Travel time to Antarctica varies depending on weather conditions and the itinerary, but typically takes 2-3 days each way.
If you have more time, consider adding additional days to explore other parts of Patagonia, such as Torres del Paine National Park. If you have less time, you may want to consider a shorter trip to Antarctica, such as a fly-in tour from Punta Arenas, Chile. Be sure to pack warm clothing, as temperatures in Antarctica can be extremely cold.
