The Sacred Valley sounds like a legend; it stretches along the Rio Urubamba, hemmed in by the steep Andes and home to the mysterious ruins of Machu Picchu. This densely populated valley is intensively farmed through irrigation, as rainfall here is moderate, as it is throughout the high Andean mountains. The Camino del Inca traces a path along the mountainsides, between remnants of the Inca empire and indigenous communities. On foot, on horseback, or by train in the class of your choice, attentive and curious, you make your way through the heart of these vast landscapes—refuge of an enduring civilisation, welcoming and rich in a folk art without equal.
