Located in the Sacred Valley, Maras is a small town home to thousands of ancient salt pans that have been used to produce salt since before the time of the Incas. Each of the salt pans is owned and operated by a different local family, and there are plenty of small stalls where visitors can purchase salt and salt-containing products. As of June 2019, visitors are no longer permitted into the crystallization pond area, but you can still see the pans from a viewpoint and learn about the salt mining process from a local guide.
