We flew from Lima to Cuzco where we were on a private tour to the Sacred Valley.  We visited the Pisac Inca Ruins and later the Ollantaytambo Inca Ruins.  They still use the amazing water systems developed by the Incas for current irrigation for the nearby farming.  We hiked and climbed to the tops of the ruins.  The rock walls show that the Incas were very unique engineers to cut their rocks for perfect fits at various angles and so tight, you cannot put anything in between them.  It is still a mystery as to how they cut them so accurately with the tools available then.  And how did they get those huge rocks up the mountainsides?  We stopped to do a little shopping at the Pisac market.  We stayed at an interesting  hotel that used to be a monastery.
