The ruins of Pisac clinc to a mountain spur a condor's nest of a place far above the valley. If the name "Pisac" ever had an specific name. It has since been lost. However P'isaca, the name of one sector of these ruins, refers to a kind of Andean partridge. Pisac ruins are filled with wonderful examples of Inca stonework and construction, set in a stupendous location. The complex seems to feature some example of almost everything the Incas did in terms of architecture, defense , religion, agriculture, roads and residential construction. For those who are fit and like to exert themselves, it is well worth the effort of scrambling and climbing up the west flank of the mountain to reach them from Pisac village. For softer adventurers, an equally impressive way to see them is to take the road from the village which loops up the Chongo valley, east of the ruins, to within about a kilometer of the Intiwatana temple sector. The highway is used almost exclusively by Tour buses, but taxis and combis to the ruins are often available for hire By the Pisac bridge. An advantage of this option is that you can hike into the ruins along a spectacular Inca pathway, through gateways and tunnels.experiencing as you walk a crescendo of stunning views of the Valley and Mount Pachatusan, to the south, beyond the river. Entrance to ruins is by T.T.
