Salar de Uyuni Background: Salar de Uyuni, at 3650 meters and 10582 square-km, is the world's largest salt flat. Once part of a prehistoric lake when the waters dried it left behind an estimated 10 billion tons of salt, of which 25000 tons is extracted annually. I am not a fan of buying guided package-tours as I usually end up feeling gypped by the end. This one was a huge exception. For a mere $70US six of us gringos were chauffeured for four days, roomed for three nights, fed giant vicuņa steaks / marinated chicken / salads for lunch, pancakes for breakfast. We were escorted to and through the salt flats, a salt hotel, to brilliant blue lake-waters populated by hundreds of pink flamingos, geysers and violently bubbling mud-pools (4800m), and -- towards the end -- air-brushed clouds and snow-capped volcano/mountain peaks. The skies were not as perfect as I wanted for photography. However, just for the food alone, I was tempted to go on a second tour with the same company (Andrea tours). 70 bucks! An amazing value.
