Pumamarca fits the bill for a first day hike in the Andes. After a gentle start there is a steep, short section up to a contour line that takes you most of the way to the ruins. The ruins are interesting in their mix of two periods and the "observatory" but not on par with the major sites. While you do not need a guide for this trip we travelled with Jose of Andean Soul. He was good company and helpful interpreting the site as well as a source of local plant and cultural knowledge.
