Since June 2002 trekking independently on the Inca Trail has been prohibited. Regulations state that persons need to register with an official agency to undertake the Inca Trail.

The INC (Institute of National Culture) is the regulatory body responsible for controlling access to Machu Picchu and the Inca Trail. Pachamama Explorers must meet their requirements providing professional guides, good camping equipment and emergency first aid kits including oxygen.
