A complete guide to the world's most legendary trekking route — its history, route, climate, archaeology, regulations, and what to expect on every step from Km 82 to Machu Picchu.
The Peruvian government strictly limits Inca Trail access to 500 people per day (about 180 trekkers + porters, guides and cooks). For high season (May–September) book 4–6 months ahead. For October–January, 3 months ahead is usually sufficient. Permits regularly sell out for July and August by January or February of the same year.
The Inca Trail is part of the 23,000 kilometers (14,000 miles) of stone-paved roads built by the Inca Empire across South America. It is by far the most famous trekking route in Peru, and arguably the most spectacular in the entire American continent. Every year over 25,000 hikers from around the world walk along these 43 kilometers of original Inca road that lead to the citadel of Machu Picchu, deep in the Cusco cloud forest.
The journey begins at the village of Piscacucho, at kilometer 82 of the Cusco–Quillabamba railway, and takes 3 to 4 days of intense trekking. The route passes through an extraordinary range of altitudes, climates and ecosystems — from high-altitude grassland (puna) at over 4,000 m to lush cloud forest at 2,400 m. Travelers cross two high passes (the highest being Warmiwañusca at 4,200 m), and finish with a magical entrance to Machu Picchu through Inti Punku — the Sun Gate.
Among the route's main attractions are the network of granite-stone settlements built by the Incas — sites like Wiñay Wayna ("Forever Young") and Phuyupatamarca ("the city above the clouds") immersed in overwhelming natural scenery. Hundreds of orchid species, multicolored birds, and dreamlike landscapes provide the ideal setting for what is, for many, a once-in-a-lifetime experience.
The total distance of the trail is approximately 39.6 km, starting at Km 82 in a place called Piscacucho. The journey begins by crossing a bridge over the Vilcanota, then heading left across a eucalyptus grove and starting the day at a calm pace.
Almost immediately you encounter the archaeological sites of Q'ente, Pulpituyoc, Kusichaca and Patallaqta. From the latter, you continue along the left bank of the Kusichaca River, where you'll see not only the bridge but also tombs, aqueducts, terraced roads and a canyon. The path leads to the small town of Wayllabamba, where you camp the first night. It takes about 4 hours to cover the 9 km to this point.
The second day is the most difficult, because you must climb to 4,200 meters, crossing the Warmiwañusca pass — the first and highest. If you suffer from soroche (altitude sickness), it's best not to stop or to descend quickly to the valley of the Pacaymayo River, where you'll camp for the second night. This stretch is approximately 7 km and takes about 8 hours of trekking.
The third day is the longest but the most interesting. You'll visit the most impressive sites along the trail: Runkurakay, the second pass at 3,800 m above sea level — a walled site with niches that may have been small resting points, guard posts, or places destined for cult activity. After crossing the second pass, you descend to Yanacocha (the Black Lagoon) and then climb a path of stone steps to Sayacmarca — a Pre-Hispanic site with narrow streets, multi-level buildings, sanctuaries, patios, canals and an external protection wall. From the top, you can see structures believed to have been a temple and astronomical observatory, with a permanent water supply and excellent food storage.
Sayacmarca is a place full of mystery and charm. The approximate distance from Runkurakay is 5 km and takes 2 hours. The site spreads over 3,600 m above sea level. There's an excellent path and a tunnel crossing the site. We recommend camping near the Phuyupatamarca ruins or 3 km further at the Wiñay Wayna visitors' center, where you can buy food and drinks or use the restrooms. The Phuyupatamarca ruins are better preserved than those seen earlier on the trail.
On the fourth day, beginning at about 5:00 a.m., hikers arrive at Machu Picchu around 7:00 a.m., after 8 km of trekking through cloud forest. Follow the marked route and drink water at the Wiñay Wayna visitors' center. Although the path is clearly marked, avoid getting too close to the cliff edges.
Camping at Inti Punku is forbidden. Leave your gear at the control post and enjoy the most important monument on this part of the continent. You'll have time to visit Machu Picchu until midday — check the train timetables for the return to Cusco.
If you plan to stay overnight in Aguas Calientes (also called "Hot Springs"), the distance from Puente Ruinas station to Aguas Calientes is 2 km, taking around 20 minutes along a narrow path that runs parallel to the railway.
The weather is relatively mild year-round, with heavy rains from November to March, and dry, warm weather from April to October — the most recommended time to visit. The trail is officially closed every February for maintenance and conservation.
The annual minimum temperature varies from 8°C to 11.2°C (46°F to 52°F). In June, July and August, temperatures can often fall below freezing at night. Maximum annual temperature ranges from 20.4°C to 26.6°C (68°F to 80°F).
The terrain is rugged, with various gorges and springs fed by glaciers that pour into the Urubamba/Vilcanota River, which crosses the area forming a deep valley running through the granite base of the Vilcabamba range for over 40 km across a variety of ecosystems.
The natural surroundings are breathtaking and the balance between Nature and Inca architecture is striking. The Vilcabamba mountains contain vast high peaks reaching up to 6,000 m, including Salkantay and Humantay. The blend of mountains, jungle and valleys creates an almost otherworldly landscape, where dawn and sunset are wrapped in mystery.
Wildlife on the Inca Trail is abundant and varied. The presence of endangered species — including the Spectacled Bear (Tremarctos ornatus), the Andean Cock-of-the-Rock (Rupicola peruviana), and the dwarf deer (Pudu mephistopheles) — was one of the reasons the Peruvian government declared the area a Conservation Unit.
The protected zone includes species such as the puma, Andean fox, river otter, taruka (Andean deer), wildcat, and ferret. Birds in the Machu Picchu Sanctuary include the Mountain Caracara, hummingbirds, torrent duck, parrots, wild turkey, and many small birds with colorful plumage.
There are also reptiles such as the Bothrops and the coral snake (Micrurus, lethal due to its venom), lizards, frogs, and numerous other Andean and jungle fauna. This abundant wildlife makes the Machu Picchu Sanctuary ideal for both tourists and researchers.
The natural areas are filled with diverse forest species varying by habitat. The forest vegetation includes trees such as cedar, romerillo (Intimpa conifer), laurel, Ocotea, Podocarpus, Guarea, Weinmannia, Clusia, Cecropia, Cinchona, Erythrina (Pisonay), and Ilex.
The ornamentals have made the Sanctuary famous: experts have identified over 90 species of orchids, plus various begonias, puyas and cacti. Most of the area is covered with grass, bushes and woody plants. The variety of conditions creates an ideal environment for the growth of plants ranging from thick subtropical jungle and cloud forest to the highest mountain tops.
Beyond the natural features, the Inca Trail's cultural heritage is unmatched. The well-built stone trail crosses dense forests and deep canyons, with 18 archaeological sites visible along the way. These include housing, irrigation canals, agricultural terraces, walls and sanctuaries — irrefutable proof of the existence of large pre-Columbian settlements.
Located 800 m east of the citadel, Aguas Calientes (officially Machu Picchu Pueblo) is named after its underground sulfur hot springs, which flow from the rock at varying temperatures. Specially built pools allow for mineral hot baths, with average water temperatures of 38°C to 46°C. There are changing rooms, sand baths and small cafés.
To reach Km 82 (start of the trek), you can take the train from Cusco to Ollantaytambo, or travel by car directly to Km 82.
The only way back from Machu Picchu / Aguas Calientes to Cusco is by train. Check current timetables before booking — schedules vary by season.
A fleet of minibuses links Aguas Calientes (Puente Ruinas station) via a narrow switchback road up to the highest point of the Machu Picchu complex. The drive takes about 20 minutes each way. Service runs daily; frequency depends on tourist demand. There is also a walking trail between Puente Ruinas and the Machu Picchu citadel that takes about an hour.
Signs are placed in different parts of the trail using a series of words and international symbols. Most provide the necessary information about specific spots — climate, distance and services available. Signs are classified as information, prevention, and restriction.
Every person entering the Historic Sanctuary of Machu Picchu must use the authorized trekking routes and follow these rules established by the government authorities:
Any violation of these regulations will result in police or park-ranger intervention to enforce the corresponding penalty. Respect the rules to avoid unpleasant incidents and help preserve this unique heritage for future generations.
