Salineras de Maras, also known as the Maras Salt Mines, is a historic salt-extraction site located in the Sacred Valley of the Incas in Cusco Region, Peru. The salt mines consist of a series of pools fed by a natural spring, which is believed to have been used by the Incas for salt production as early as the 13th century. Today, the site is still in use and operated by local families who extract salt using traditional methods passed down through generations. Visitors to the Salineras de Maras can observe the salt-extraction process and purchase locally-made salt products. The site is also known for its scenic beauty, surrounded by the Andes mountains, and is often included in tours of the Sacred Valley.
