The Maras Salt Mines haven't changed much since the Incas created them over 1,000 years ago. The 3,000 pools built into the hillside produce pink salt, bath salt, and flavored salt, and yields around 150 kilograms per month. Through the simple process of evaporation and other primitive harvesting techniques, the farmers bag the salt and sell it in local markets. Due to the cost of shipping the heavy salt in such a remote area, you won't be able to purchase it anywhere else. The thousands of pools provide a stunning geometric landscape along the mountain side, which will be a for sure unforgettable view.
