The Sacred Valley is a region in Peru's Andean highlands. Along with the nearby town of Cusco and the ancient city of Machu Picchu, it formed the heart of the Inca Empire. Stretching roughly 60 kilometers, it’s an area of fertile farmland and Spanish colonial villages like Pisac and Ollantaytambo. Pisac is known for its Sunday handicraft market and hilltop Incan citadel.
