East Antarctica
East Antarctica may take some effort to reach from North America, but these longer expeditions explore some of the least visited, wildest and most historically significant regions of the White Continent. Only a few East Antarctica and Ross Sea expedition cruises depart each year. From the US, you'll fly to Australia or New Zealand to board your cruise, rather than South America.
The intense journeys to East Antarctica usually span 25-30 nights in the peak Southern Hemisphere summer months of January and February, with the season limited due to sea ice accessibility.
