Yes, you must obtain a permit to hike the Classic Inca Trail to Machu Picchu route. Permits allow the Peruvian government to protect the landmark for its natural and historical significance. Therefore, only 500 individuals are allowed on the Classic Inca Trail tour each day from KM 82. Around 300 of these will be porters, guides and other staff, which leaves room for 200 trekkers that can join the trail per day. Due to the global popularity of this trek, permits must be purchased before you leave for Peru – sometimes many months before a trip commences, so plan ahead. The Explorer’s Passage can help!
