Inca Trail Introduction

When discussing the Inca Trail, it’s important to understand that the Incas developed an extensive network of nearly 40,000 kilometers of trails to connect their expansive empire, which reached from Quito in Ecuador down to Santiago in Chile and east to Mendoza in Argentina. At the heart of this empire was Cusco. Most of the primary trails in the mountains surrounding Cusco were either built or improved by the Incas. However, a particularly scenic 43km section of mountain trail connecting key Inca archaeological sites such as Runcuracay, Sayacmarca, Phuyupatamarca, Wiñay Wayna, and Machu Picchu has gained popularity with hikers over the last 30 years and is now known as the “Inca Trail to Machu Picchu.” Access to this section is tightly controlled, with only authorized trekking companies permitted to sell this trek. All guides must be licensed, and a limited number of trekking permits are issued, which must be purchased several months in advance (see Inca Trail Permit Availability). When booking an Inca Trail tour, always choose a reputable trekking company and review the day-by-day itinerary. If the itinerary doesn’t include visits to all the listed archaeological sites, you might be looking at a different trek. Be cautious of unscrupulous travel agencies in Peru that mislead visitors about their route. This guide ensures you won’t be one of the misled.

The Classic Inca Trail 4 days 3 nigths

This guide primarily covers the Classic Inca Trail, starting at Km82 (named because it is 82 kilometers along the railway from Cusco to Machu Picchu). This trek typically takes 4 days, culminating at the Machu Picchu ruins at sunrise on the fourth day. The trek is moderately challenging, and reasonably fit individuals should manage it. However, it does reach altitudes of 4200m, so proper acclimatization is crucial. If you’re coming from sea level, plan to spend at least 2 full days in Cusco before starting the trek. This will allow time for acclimatization and provide an opportunity to explore Cusco and nearby Inca ruins such as Sacsayhuaman, Q’enko, Pucapucara, and Tambomachay, as well as the Sacred Valley of the Incas, including Pisac’s traditional market town and the fascinating Inca fortress at Ollantaytambo.

The Classic 4-day Inca Trail can be hiked year-round, although the driest and most comfortable months are from April to October. June, July, and August are peak season, so reservations should be made well in advance. The trail is closed each February for conservation work. January and March are in the wet season, making the trek less enjoyable without proper rain gear. See When to Go for a detailed weather description on the Inca Trail.

Although most people complete the trek in 4 days, some prefer a 5-day version to avoid busy campsites. However, groups on this trek usually reach Machu Picchu around midday on the fourth day (when it is busiest and less photogenic) and won’t have time to explore until the next day. For most visitors, the classic 4-day trek with an extra night in Aguas Calientes is more suitable and cost-effective.

The Short Inca Trail

Two main alternative treks to the Classic 4-day Inca Trail also end at Machu Picchu. The first and most popular is the Short Inca Trail, which can be completed in 1 or 2 days. This easier trek starts closer to Machu Picchu at kilometre 104 along the Vilcanota River Valley. Trek permits are required, so book several months in advance.

The Salkantay & Inca Trail Trek

The second alternative is the more strenuous 7-day trek via Salkantay, a beautiful snow-capped mountain. This trek, typically completed in 7 days (experienced trekkers might manage in 6), starts near Mollapata and spends the first 3 days trekking around Salkantay. On the fourth day, it joins the Classic Inca Trail route, visiting Inca archaeological sites like Runcuracay, Sayacmarca, Phuyupatamarca, Wiñay Wayna, before reaching Machu Picchu on the final day. This trek combines stunning snow-capped mountains and Inca ruins. Since permits are required, book this trek well in advance. Trekking companies rarely offer this as a group service, and if they do, it can be costly. Booking a private tour is the best option, especially if you’re with friends or a hiking club.

Choosing an Inca Trail Tour Operator

When searching for information on the 4-day Inca Trail, you’ll find hundreds of companies offering this trek. Many act as agents for the few specialist trekking companies that operate the trek. Prices range from around US$650 for basic services (including entrance fees and return train) to $1500, depending on the comfort level. Booking directly with a local tour operator in Cusco can be much cheaper than booking through an agent in your country. However, choose your tour company carefully, especially when booking online.
