This tour takes you to some of the most interesting Inca sites in Cusco. The tour begins with a visit to the colonial city of Maras and its church. From Maras we continue to the nearby Inca site of Moray, a magnificent series of terraced circles on the ground that were once used by the Incas to experiment with crops. Our final destination is the salt mines that have been in operation since pre-Inca times. The water from an underground stream is conducted through basins where it evaporates and leaves crystals of pure salt. With thousands of sparkling white pools that stretch across the valley, the view is breathtaking.
