The Choquequirao Trek to Machu Picchu?

The Choquequirao trek is the 4-day to 9-day trek in the Vilcanota mountain range. The 4-day route will take you steeply into the Apurimac canyon, up the other side to Choqeuquirao Trek, and back out the same way. The longer Choquequirao trek to Machu Picchu takes you down and out of the canyon through Choquequirao, then along trails that eventually link with the Salkantay to Machu Picchu.
