The World's Cleanest Air

Clean-Air Credentials: “The southern tip of South America is really clean,” says Harvard University’s Daniel Jacob. It’s so clean, in fact, that the baseline air monitoring station located just three miles from the Argentinean city of Ushuaia still effectively records zero pollutants for much of the year. A combination of Southern Hemisphere advantage, remote location, and 160 rain days a year makes for a very breathable environment.

Take a Breather: Strap on some hiking boots and head for the lakes. Country Walkers conducts walking tours of Patagonia and Chile’s Lakes district, including Torres del Paine National Park, a mountainous glacial region declared a UNESCO World Biosphere Reserve in 1978.
