You don’t reach Machu Picchu only by train or along the famous Inca Trail. There’s an alternative route, known as the Santa María route or simply Hidroeléctrica. It’s the cheapest and most adventurous option, popular with backpackers and travelers who want something different.
But many people ask: is it safe? How does it work? Here is what you need to know to decide whether this route is for you.
What is the Hidroeléctrica route?

The Hidroeléctrica route is an alternative way in that combines a bus ride with a walk to Aguas Calientes, the base town for Machu Picchu.
- Bus from Cusco to Hidroeléctrica. The ride takes 6 to 7 hours, passes through the Sacred Valley and then drops down toward the high jungle. It’s a long, winding drive, but the scenery is spectacular.
- Walk from Hidroeléctrica to Aguas Calientes. Once you reach Hidroeléctrica, it’s about 10 km (6 miles) on foot (2 to 3 hours) along the train tracks to the town.
Safety and weather through the year
From October on, the weather in the jungle area (Aguas Calientes and Hidroeléctrica) starts to change.
- Rainy season risks. The main risk on this route during the rainy months (November to March) is landslides on the road between Santa María and Santa Teresa.
- October, a transition month. In general, October is a safe month. Rain is sporadic and usually not heavy enough to close roads. It’s a great time to see the lush vegetation.
Safety tip. If you go on your own, make sure the vehicle you hire is in good condition. With Tari Tours, you can travel with peace of mind: we only work with licensed, safe transportation.
Pros and cons of the alternative route
| Aspect | Pros | Cons |
|---|---|---|
| Cost | It’s the cheapest way to get to Machu Picchu. | You pay for the savings with travel time (7 hours by bus). |
| Scenery | You see another side of Peru as you head into the high jungle. | The 3-hour walk runs alongside the train tracks, with no archaeological sites. |
| Comfort | It doesn’t take much physical effort (apart from the final walk). | The bus ride is long and can be tiring. |
Is this route for you?
If your priority is traveling on a tight budget and you have time to spare, the Hidroeléctrica route is a good adventure.
If, on the other hand, you put time, comfort and a historical experience first (like the Inca Trail or the Sacred Valley), we recommend going by train or choosing a package with fewer transfers.
