The site of Choquequirao is another lost city of the Incas that is hidden high on a ridge 1,750 meters above the raging glacier-fed Apurimac River and is surrounded by snow-capped peaks. The intricacy of these majestic ruins suggests that Choquequirao was once of high importance to the Inca empire. Before a bridge was constructed over the Apruimac River, the site was remote and mostly inaccessible. Luckily for explorers this bridge can now connect them to this once hidden ancient city. Enjoy a 4-day trek to visit these amazing ruins.
