Since June 2002 trekking independently on the Inca Trail has been prohibited. Regulations state that each trekker must be accompanied by a professionally qualified guide.

The UGM (Unidad de Gestion Machu Picchu) is the regulatory body responsible for controlling access to Machu Picchu and the Inca Trail. Pachamama Explorers must meet these requirements proving professional guides and good camping equipment,radio communications and emergency first aid including oxygen.
