A stage almost compulsory in Peru. There are very different treks; all of them are worth it.
The Inca Trail is the most famous (it’s recommended to book it in advance) and is the only one that offers you to reach the Machu Picchu on foot.

As an alternative, we offer to people having an exquisite taste the Lares Trek that includes the visit of Machu Picchu, or the Choquequirao, a jewel still untouched by mass tourism.
