We visited the Inca ruins at Qenko and the nearby site of Sacsayhuaman on our last full day in Cuzco. We took a short taxi ride to Qenko and walked back to the city through Sacsayhuaman. Qenko apparently means 'zigzag'. The name probably comes from the zigzag channels in the site. This site is unusual in that it has a cave with altars carved from the rock.
