The World's Cleanest Air
Clean-Air Credentials: The wind arriving at Baring Head meteorological station at the bottom of New Zealand’s North Island, under a chilly southerly airstream, originates from an area of almost no human activity whatsoever—the oceans around Antarctica. Drink it in on the South Island: with just 25 percent of the country’s population, there are fewer people upwind.
Take a Breather: Make doubly sure that every breath is pure by leaving the land and learning the fine art of mountain soaring. Glider pilots climb the mountain thermals to cruise at 12,313 feet over the snow-covered peak of Mount Cook, New Zealand’s tallest point. Go with Southern Soaring.
