I’ve been taking a break from work this week and following the course of the Vilcanota River  through the Sacred valley of the Incas.  We started in the market town of  Pisac    and wandered through the amazing terraced  landscape where the townspeople’s ancestors perfected the art of cultivation at different altitudes. The next day we were on to Urubamba and then Ollantaytambo. Today we hiked to the Inti Punku (Sun Gate) and then descended to spectacular Machu Picchu – if you haven’t seen it, put it on your itinerary!

All of these places display an extraordinary dialogue between humans and nature. Where does the mountain end and the stonework begin?
