Since June 2002, trekking independently on the Inca Trail has been prohibited! State regulations set that each trekker has to be accompanied by a professional Tour Guide! Although, trying to hire a private Tour Guide in advance is difficult since travel agencies are not interested in hiring out their Tour Guides. However, if you wait until you arrive to Cusco to arrange your Tour Guide, there is a very high probability that all Inca Trail permits will be already fully booked. If you have a good luck during a rainy low season and there is still an Inca Trail permit left, you will likely find the worst Tour Guides as the all professionals work for good travel agencies.
