The trek to Choquequirao, often referred to as the little sister to Machu Picchu, makes a challenging alternative to the classic Inka Trail. The four day return trek to the remote archeological site (currently, hiking is the only way to reach it) sees far fewer tourists than its famous cousin. While in truth this is not one of my personal favorites, other hikers on the trail told me that it was some of the most beautiful scenery they had ever seen.
This page outlines posts related to this 4 day/ 3 night trek completed in September of 2015.
