The Inca trail to Machu Picchu, the “Lost City of the Incas”, is a world-famous trek in Peru. It’s the best known part of the Inca road system, which was listed as a UNESCO World Heritage site in 2014. The trail requires reservations months in advance, and all trekkers must be part of a tour group, which includes a guide and porters. Treks vary significantly in style, from budget backpacking to high-end glamping, but typically consist of 4 days and 3 nights on the trail itself. While the main route is fixed, timing and campsites vary.
Visits generally start from Cusco, the capital of the Incas. Due to the need to acclimatize to the altitude for a few days, the trek itself must be part of a longer trip, usually a few days in Cusco and the Sacred Valley; see Inca Highlands.
