A highlight of the Colca Canyon is a stop at Cruz del Condor, the pass where condors soar gracefully on the rising thermals occurring as the air warms. You'll want to be there early to see the condors in flight.
In addition to the Colca Canyon, the La Calera hot springs at Chivay are a wonderful way to relax after a day's touring, and the Toro Muerto cemetery of the Wari Indians. The final resting place of these Indians, buried in a fetal position, is built in a 90° steep cliff face and seeing it, you wonder how the burial party managed.
