Winding through the cloud forests and jagged granite passes of the Peruvian Andes, the Classic Inca Trail is among the world's most iconic archaeological pilgrimages. Terminating at the Sun Gate (Inti Punku) with an unmatched panoramic vista of Machu Picchu, completing this 43-kilometer trek requires thorough logistical planning and physical readiness.
Permit Caps & Booking Timelines
To preserve the fragile stone paving and historic Inca sites, the Peruvian Ministry of Culture strictly limits trail access to 500 permits per day, with roughly 300 allocated to licensed guides, porters, and kitchen staff, leaving only 200 daily permits for trekkers.
- Booking Window: Permits for the following calendar year release annually in October/November and sell out within minutes for peak months (May through September).
- February Closure: The entire Inca Trail is closed every February for conservation maintenance, trail cleanup, and biological recovery.
Altitude Acclimatization in the Sacred Valley
Altitude sickness (Acute Mountain Sickness - AMS) is the primary physical challenge of the Inca Trail. On Day 2, trekkers conquer Dead Woman's Pass (Warmiwañusqa) at an elevation of 4,215 meters (13,828 feet).
Day-by-Day Trek Itinerary
