Antarctic: Pristine Arctic Nature.
The coldest, driest continent on Earth with the highest average elevation, this is not a location with any actual residents, much less cities. But, that’s part of the reason Antarctica is home to some of the most breathtaking scenery and unique wildlife you’ll ever see. From November to March, visitors can travel through the Arctic Sound, a.k.a. Iceberg Alley, where they’ll see spectacular 10,000-year-old glaciers, their colors ranging from brilliant white to deep aquamarine. Also a must-see are the volcanic South Shetland Islands—Zodiac excursions get travelers close to the action while spotting humpback whales and emperor penguins.
