Fewer than 20,000 cruise passengers make it onto “The White Continent” each year, making it one of the least trafficked destinations on the map. It’s no wonder the destination is so under-visited; it usually takes more than 12 hours of flying time to the port of embarkation, and harsh weather conditions can yield some rough days at sea. In short, you come on a cruise to Antarctica because it’s one of those places you simply always have wanted to go. Of course, you also come for the sights—tens of thousands of penguins, icebergs the size of football fields, whales spouting in the distance, and giant mountains blanketed with snow. If resources allow, opt for a guided adventure like those from Lindblad Expeditions; these cruises are staffed with naturalists who are trained to interpret nature and teach you a little something along the way.
