That isn't a lake, the sea, or a beach you can see, but an enormous salt flat in Bolivia, in the Andes at 3,656 meters (11,995 ft) above sea level. Even though there is a pool of brine underneath the salt, it is the main route across the Andes Altiplano. the brine contains high concentrations of minerals, including over half the world's supply of lithium.
The Salar de Uyumi means salt flat with enclosures, probably referring to the "islands" like the one seen here. The card shows Isla Inkawasi which has enormous cacti and a tourist centre. Tourism is one of Bolivia's main sources of income and this place is one of the main sights. Hotels are built from salt blocks which no doubt has novelty value but I can't imagine they are the height of luxury.
