Decide to visit the Bolivian Salt Flats wet or dry. The plains of the Bolivian Salt Flats are, during part of the year, flooded with a shallow expanse of water. During the rainy season the flats reflect the sky like an enormous mirror. Because the water only rises a couple of feet cars can still travel across it. There is the risk, however, of being prevented from travel by heavy rain. From May to November (wintertime in the southern hemisphere), the water evaporates. If you want to see a second sky at your feet, you can take your chances with the rain, but wintertime travel is less likely to be hampered by the weather.
