The journey to Machu Picchu via the short Inca Trail 2 days doesn’t begin in a typical town or at a bus station. Instead, it starts at a very specific spot: a kilometer marker next to the train tracks, known as KM 104. Also known as Chachabamba, this isolated spot in the high jungle is where the train stops in the middle of the Urubamba Canyon, marking the start of your 2-day trekking adventure.
Because this checkpoint is strictly regulated by the Peruvian government, it’s important to know exactly what happens here to ensure your hike gets off to a smooth start.

Where is the KM 104 Checkpoint?
KM 104 is located in the Sacred Valley, along the railway line connecting Ollantaytambo with Aguas Calientes (Machu Picchu Pueblo).
- Elevation: 2,100 meters (6,890 feet) above sea level. This is significantly lower than Cusco (3,400 m), meaning the climate here is warmer, more humid, and lies right on the edge of the Andean cloud forest.
- How to get there: The only way to reach KM 104 is by train. There are no roads leading to this location. Your Wari Expeditions guide will coordinate with the train conductor to ensure you get off at the right spot, as the stop only lasts a few minutes!
What to expect at the checkpoint
Once you step off the train, you will cross a suspension bridge over the Vilcanota (Urubamba) River. Immediately after crossing, you will arrive at the official SERNANP (National Service of State-Protected Natural Areas) control booth.
Document Check (Essential)
This is a government checkpoint where regulations are strictly enforced. To pass through the checkpoint and begin the hike, you must present the following to the park rangers:
- Your original passport: This must be the physical, original passport. Copies or photos on your phone will not be accepted.
- Matching Information: The passport number must match the one you provided to your agency when purchasing the Inca Trail permits. If you renewed your passport after making the reservation, you must bring both the old and new passports.
- Physical Permits: Your guide will carry and present the official printed Inca Trail permits for your group.
Services available at the starting point
Kilometer 104 is not a town, but a simple park ranger station. However, it offers some essential services that you should take advantage of before starting the hike:
- Restrooms: You’ll find basic restrooms here. We strongly recommend that you use them, as the nearest restrooms are several hours further along the trail, at the Wiñay Wayna campsite.
- Information area: There is a shaded area where your guide will give you a final briefing, hand out your packed lunch, and give you time to organize your backpack.
Why Choose the KM 104 Route?
The KM 104 route is ideal for travelers who want to experience the authentic Inca Trail but have limited time or prefer a less demanding trek than the Classic 4-Day Inca Trail. The trail covers approximately 12 kilometers (7.5 miles), includes original Inca pathways, archaeological sites, cloud forest landscapes, and the unforgettable arrival through the Sun Gate. It combines adventure, history, and comfort, with an overnight stay in Aguas Calientes before a guided visit to Machu Picchu on the second day.
