In the southwestern corner of Bolivia, about an hour’s flight from La Paz, the blinding white Salar de Uyuni salt flat stretches for more than 4,500 square miles. There is no place else like it in the world.
At nearly 12,000 feet above sea level, the Salar dazzles the eye and plays optical tricks on you with what look like white hexagonal tiles of salt that seem to go on forever. In winter (our summer), you can drive across it. In summer (our winter), the Salar becomes a giant puddle, and the reflection of sky and clouds seems to reflect the entire world.
The Salar was formed after a lake dried up that had covered most of southwestern Bolivia between 40,000 and 25,000 years ago. Another lake lasted about 1,000 years. Salt deposits were leached from the surrounding mountains and, with no outlet to the sea, were deposited here, the lowest point on the Altiplano plateau. (An estimated 50% of the world’s lithium, used in batteries and cellphones, is under the Salar.)
Until 2011 the Uyuni airport was just a landing strip for mining companies. Now there is a terminal, an extended runway and daily flights from La Paz. Visitors can now get to the salt flats without spending days to do so.
We took a 6 a.m. flight to Uyuni and arrived before sunrise to begin our three-day tour with Red Planet Expeditions (www.redplanetexpedition.com, about $190 per person). We hurtled across the salt flats in our caravan made up of three 4X4s, each with four to six people, and climbed around the “island” of Incahuasi, a rocky land mass (and national park) that rises out of the salt flats and is covered with cactuses.
We took ridiculous pictures on the salt flats, playing with the lack of perspective caused by the flatness, the whiteness and the hazy blue distance of the horizon. We saw herds of wild vicuñas and chased domesticated llamas out grazing for the day. We saw fields of quinoa, a protein-laced grain with which America seems to be having a love affair, and rock formations sculpted by the desert winds. We saw an Andean fox, which looks like a hairier version of its American counterpart. Wild ostriches ran alongside our 4X4, their feathers bouncing. We were really lucky to see them.
On the second day of the tour we visited the Reserva Nacional de Fauna Andina Eduardo Avaroa, a national park that is Bolivia’s most visited and protected area. We saw volcanoes, geysers, flamingos and red and green lagoons. Although it was bone-chillingly cold — it was the dead of the Bolivian winter — that night we soaked in a natural hot spring under a sky full of stars.
As Salar de Uyuni develops as a tourist destination, a trip here will get easier but it will never get more beautiful.
