Salar de Maras - Peru
While the salt mines are set up for tourism, complete with little shops selling bottled water, felt alligator slippers, and packaged spa sea salt, you may find that you are the only tourist there. The desolation of the place lends to the otherworldly feel that embodies Salar de Maras.
Built on the side of Qaqawiñay mountain, approximately 3,000 small wells fill with salt water from a natural spring above them. When the water evaporates, the salt left behind gradually solidifies, and is ready to be harvested. The salt is collected by hand by barefoot workers, who load the salt into sacks to haul down the hive-like structure.
The salt mines are northwest of the town of Maras, and are open to the public.
