Not everyone knows about Ushuaia. It's commonly called the southernmost city in the world. The average temperature ranges from 50 degrees Fahrenheit in January to 34.9 degrees Fahrenheit in July.

The extreme temperatures are more forbidding. The record low was -13 degrees, not counting the wind. It rains or snows there 200 days a year. And you wouldn't ever want to visit, unless you appreciate extreme travel. Ushuaia is the most common port to the End of the World.

 The coldest place on earth.

While some records might make it disputable. Antarctica —the End of the World — is consistently the coldest. And while it is not considered dangerous per se, travelers are always warned that the remote location, frozen landscape and unpredictable weather can make operations in Antarctica a logistical nightmare.

Once you're there, assuming you book your trip with a tour company that includes land-based operations, anything is possible. You could try ice climbing or brave a mini-expediation into a landscape known as a world of snow and profound silence. Everything is white.

The climate is cold and dry. While some locations that cater to tourists are moderately cold, about -13 degrees Fahrenheit, more adventurous travelers are generally told to plan for colder weather. Mount Vinson and the South Pole frequently drop to -40 degrees Fahrenheit. Severe storms can roll in any time. But the landscape it unlike any other in the world.

People see all sorts of things there. And many tours are sure to include Zodiac trips past massive icebergs or, if you're lucky, amazing animal sightings such as penguins, orcas, and sea lions. Others are even more hands on — affording you the chance to take the helm, handle the sails, and even set the course.

While there are dozens of variations, TourGuy.com recommends choosing a tour operator that is a member of the International Association Of Antarctica Tour Operators. This member organization adheres to our polities, working to ensure safe and responsible private travel for the 30,000 people a year in need of adventure.

 The hottest place on earth. 

At the other extreme is Death Valley National Park, which is located primarily in the Southern California Desert and part of Nevada. It is the largest park in the United States and one of the most desolate environments in the world.

While not nearly as large as the southern extreme, Death Valley includes 3.4 million acres of land. Although surrounded by sweeping mountain ranges, Death Valley is the lowest point in North America. The absolute lowest point, Badwater Basin, is 282 feet below sea level.

You would never want to visit in the summer (but some people do), unless you appreciate extreme travel. Actually, the travel is much less extreme than the environment. The average temperature ranges from well over 120 degrees Fahrenheit in the summer to 60 degrees Fahrenheit in the winter.

At its most extreme, Death Valley recorded the second hottest recorded temperature on Earth, reading a scalding 134 degrees Fahrenheit. However, that record was set at a location typically four degrees cooler, which means Death Valley might have set the record.

If you go during the hottest months, the heat will hit you like opening the door of an oven. You can see it rising off the desert floor. On any blacktop, tires sometimes stick to the road. There is nothing quite like it. It's not impossible to be taken in by a mirage.

Fortunately, the winter months are much more forgiving, but no less enjoyable. With such a huge stretch of untouched and protected land, Death Valley has some of the most dramatic ecological wonders in the United States: sand dunes, marbled rock, sun-baked mud, and salt flats.
