The New Yor Times has a great article in their Travel section entitled Taking The Back Road To Machu Picchu that is a great look at hiking the Inca Trail. It’s an excellent read if you have an interest in taking that trip, which is an epic hike to be sure, any time in the future. The article talks about how the traditional Inca Trail has gotten crowded and has had issues with trash and refuse since it was opened to the public, and that there are now several “alternate” versions of the trail to hike.
The Inca Trail winds through the the Peruvian Andes reaching heights of nearly 14,000 feet, and offering some stunning views of the mountains. You can read more about it here.
