Inca Trail to Machu Picchu Archaeological Site

Classic 4-day route covering roughly 43 kilometres from the high Andes down to Machu Picchu near Cusco in Peru.

Time to Hike: About 4 days and roughly 43 km in total, with daily walking typically 5 to 8 hours depending on the itinerary and group pace.

Best Time to Go: Main trekking season is the dry months, with clearest weather from May to September and the busiest period in June to August.

Getting there: Most operators collect walkers from Cusco or Ollantaytambo and drive to the official trailhead at Piscacucho (km 82). The route finishes at the Sun Gate and descends into Aguas Calientes for the final visit to Machu Picchu.

Costs: You must book through a licensed operator because permits are required; expect organised 4-day trips to range broadly in price depending on inclusions, with extra costs for train tickets, entry to Machu Picchu and optional bus from Aguas Calientes.

Difficulty: Steep stone staircases, long ascents and descents and a high pass around Warmiwañusca at roughly 4200 metres make the trail physically demanding. Altitude sickness, narrow sections and rapidly changing weather are the main hazards.

The Inca Trail threads through high puna grassland, elfin forest and lower cloud forest as it descends from the Andean highlands into the Urubamba valley. Ancient stone causeways, terraces and stairways appear repeatedly, set among sweeping mountain views and occasional waterfalls.

Highlights include well-preserved sites such as Wiñay Wayna and the approach to Inti Punku the Sun Gate, where the first sight of Machu Picchu greets walkers at sunrise. There are no mountain huts on the official trail - camping is at designated government campsites and all groups travel with licensed guides and support staff.

What makes the route notable is the combination of compact distance, high-altitude scenery and a sequence of archaeological sites that end at one of the most famous Inca citadels; strict permit limits also keep numbers controlled compared with other local walks.

Nearest airport is Cusco Alejandro Velasco Astete International Airport. Most trekkers fly into Cusco then meet their tour operator for a road transfer to the trailhead at Piscacucho (km 82) or take a short train/road leg via Ollantaytambo.

The trail finishes in Aguas Calientes (also called Machu Picchu Pueblo), from where you take a short bus or a steep walk up to Machu Picchu for your timed entry. Most itineraries walk the trail towards Machu Picchu rather than the reverse.

The walkable season runs mainly from May to September when rainfall is lowest and paths are firmer; June to August is busiest and permits sell out earliest. The wet season from November to April brings heavy rains, slippery steps and occasional trail closures.

Permits and places on guided treks are limited and often require booking several months in advance; you will need to provide passport details when your operator applies for the permit. Expect cold nights, strong sun at altitude and sudden mountain storms even in the dry season; acclimatise in Cusco for at least two days before starting.
