The Inca Trail is part of the
Machu Picchu
Sanctuary, a protected area of 32,592
hectares, managed by the National Institute
of Natural Resources, INRENA. Every visitor
must obey park regulations prohibiting
littering, cutting or damaging trees,
removing or damaging stones of ruins and the
Trail, removing plants, killing animals,
lighting open fires or camping in the
archeological sites
The trail is scattered with
ancient monuments and Incan sites
and is definitely worth the effort.
