It is a hard walk. This is because it is necessary to cross the Apurímac canyon on foot. In general, the first day you descend 1,500 m (4,921 ft), which involves steep and slippery descents, the next day you climb again 1,500 meters to reach the Choquequirao ruins. Both days involve a series of back swings that are strenuous for all types of fitness.
Some Choquequirao trek operators will tell you that the difficulty of the Choquequirao trek is not too bad because they are not high altitude. Well again, I think some honesty is in order. The Choquequirao trek is one of the lower altitude treks in the Cusco region, that does not mean it is low! In fact, you start at 3,300m (10,826ft) on the first day, and by the second day (depending on the route you take) you’ll be back above 3,000m.
To put that in perspective, the highest state capital in the US, Santa Fe, New Mexico, is only 2,180m and Denver Colorado is only 1,500m – 1,700m (that’s the height of the lowest point on the hike! !)
