Prepare to be amazed by a view that looks like a blanket of snow cascading down the mountainside. You're looking at the Salineras de Maras, thousands of shimmering, terraced salt pans that have been harvested by local families since before the time of the Incas. It's a short walk from the entrance down a few sets of stairs to the main viewpoints, where you can watch the ancient process unfold and feel the history of the Sacred Valley. The sheer scale and intricate pattern of the pools against the Andean landscape is something you won't forget.
