How to Get to Machu Picchu

The train, the trek, or the back door

Machu Picchu hides at the end of a steep cloud-forest gorge with no road to its gate, and that single fact shapes every journey to it. You arrive one of three ways: by train into the valley town of Aguas Calientes, on foot over the mountains via a multi-day trek, or by the long, cheap Hidroeléctrica combination of road and walking that budget travellers favour. Whatever the route, the last stretch is the same — a shuttle bus, or a steep stairway, up to the citadel itself.

Almost everyone starts in Cusco, the regional gateway and the place to acclimatise, then moves down through the Sacred Valley to the rail line. This hub sets the options side by side so you can pick the one that fits your time, budget and appetite for walking; the linked guides take each in depth.

There is one logical chain that every route shares, and it is worth fixing in your mind before you book anything: Cusco (the airport and acclimatisation base) → the Sacred Valley, usually Ollantaytambo (where most trains start) → Aguas Calientes, also signposted as Machu Picchu Pueblo (the town at the foot of the mountain) → the shuttle bus up the switchbacks → the citadel gate. The train covers the middle leg; the trek replaces it with a footpath; the Hidroeléctrica route swaps the train for a long minibus ride and a riverside walk. Everything else is detail.

• Train — fastest and most comfortable; book the timed entry ticket first, then the train, then a night in Ollantaytambo or Aguas Calientes around it. Best for most visitors and anyone short on time.
• Trek — the Inca Trail, Salkantay or Lares turn the approach into the trip; you need days, fitness and (for the classic Inca Trail) a permit booked months ahead. Best for walkers who want the arrival earned.
• Hidroeléctrica — a long road-and-foot route via Santa Teresa that trades comfort for cost. Best for budget travellers with time to spare; avoid it in the wet season when the road is landslide-prone.
• Whichever you choose, the final climb from Aguas Calientes to the gate is the same shuttle bus (or a steep stairway) — there is no road that drives you to the ruins.

By train — the standard route

For most visitors the answer is the train. Two operators, PeruRail and IncaRail, run the line that hugs the Río Urubamba down into the cloud forest, ending at Aguas Calientes station a short walk from the bus stop. Most departures leave from Ollantaytambo in the Sacred Valley, which is why so many itineraries spend a night there before the citadel. Service tiers run from panoramic tourist trains to luxury carriages, and bimodal options pair a bus from Cusco with the train for the lower stretch.

The reason so many trains start at Ollantaytambo rather than Cusco is altitude and gradient: the line from Cusco's Poroy area climbs and twists slowly, so the practical, reliable departure point sits down in the Sacred Valley. From central Cusco you reach Ollantaytambo by road in roughly the time it takes to cross a city and a valley — a colectivo, a private transfer or a tour shuttle — and that road leg is itself a gentle descent that helps with acclimatisation. Trains then run down to Aguas Calientes; from the station it is a few minutes on foot through town to the bus stop for the citadel.

Choosing between the operators is mostly about schedule and comfort rather than route, since both run the same line. Compare departure times against your timed entry slot first, then price and carriage class. Luggage is limited to a small bag per passenger on the tourist services, so leave the big case at your Cusco or Ollantaytambo hotel. Treat exact fares, timetables and class names as things to confirm on the operators' own sites at the time you book — they change with the season.

• Book in this order: timed entry ticket → train → bus up → any night in Aguas Calientes. The ticket's slot dictates which train you need.
• Most trains depart Ollantaytambo; reach it from Cusco by colectivo, private transfer or tour shuttle (a scenic, downhill drive through the Sacred Valley).
• Pack light for the train — tourist services cap each passenger to a small day bag; store the rest in Cusco.
• In the busy dry season, popular morning and early-afternoon departures sell out well ahead — reserve as soon as your entry ticket is fixed.

On foot — the treks

Walking in turns the journey into the destination. The classic four-day Inca Trail is permit-capped, sells out months ahead and closes every February for maintenance, but it delivers you to the Sun Gate for the first view rather than to the bus stop. Permit-free alternatives — the Salkantay over its high pass, the quieter, more cultural Lares — need no government permit and can be booked closer to your dates. All of them end at the citadel; the trail you choose shapes the entire trip.

The single most important thing to know about the classic Inca Trail is that it is permit-limited and must be booked through a licensed operator a long way ahead — months for high-season dates. You cannot walk it independently, and the February maintenance closure is annual, so plan around it. The Salkantay is the usual answer for those who decide late: it crosses a dramatic high pass and needs no government permit, though its altitude makes prior acclimatisation in Cusco or the Sacred Valley non-negotiable. The Lares route trades summit drama for villages and weaving culture and is the gentlest of the three on the body.

Every trek still ends the same way: you walk in to Machu Picchu (the Inca Trail arrives over the Sun Gate; the others typically finish at Aguas Calientes and take the bus up the next morning). So even committed trekkers need to understand the train and bus logistics for the way out — and for the rest day many people sensibly build in before or after.

• Inca Trail (classic, ~4 days): permit-capped, book months ahead through a licensed operator, closed each February. Arrives over the Sun Gate.
• Salkantay: no permit required, bookable closer to your dates, but high and demanding — acclimatise first.
• Lares: cultural and quieter, gentler underfoot; a good choice if villages and scenery matter more than a summit pass.
• Treks (other than the Inca Trail) usually end at Aguas Calientes; you still take the shuttle bus up to the gate the next morning.

The back door — the Hidroeléctrica route

The cheapest way in skips the train altogether. Minibuses run from Cusco over a high pass and down towards Santa María and Santa Teresa to the Hidroeléctrica station, where a flat, scenic footpath of a couple of hours follows the railway line into Aguas Calientes. It is long, it is a full day, and it suits travellers with more time than money — backpackers, students, anyone happy to trade comfort for a much lower cost.

Two cautions matter. First, the mountain road is winding and, in the wet season, vulnerable to landslides and delays; this is not the route to choose if your entry ticket is the next morning and you have no slack. Second, you are still walking the last stretch and then taking the bus up to the gate, so it saves money rather than effort. In the dry season, with a buffer day, it is a genuine adventure; in the wet season, treat the train as the safer choice.

• Day-long minibus from Cusco to the Hidroeléctrica station, then a ~2-hour flat walk along the rail line into Aguas Calientes.
• Cheapest option by far; best for budget and time-rich travellers.
• Wet-season caution: the road is landslide-prone — build in a buffer day and prefer the train if your slot is tight.

The last leg, and a note on altitude

However you reach Aguas Calientes, the final climb to the gate is the same: a shuttle bus up the switchback road (the first buses leave before dawn for early entry slots) or a steep walk up the stairway for those who prefer their own legs. Plan this leg with a comfortable buffer before your timed entry window.

One counter-intuitive point underlies all of it: the citadel is lower than Cusco, so most altitude trouble happens at the gateway, not the ruins. Cusco sits at roughly 3,399 m, the Sacred Valley floor a good deal lower, and the citadel itself around 2,430 m — so the journey in is largely a descent. The practical lesson is to acclimatise low first: give Cusco or, better, the lower Sacred Valley a couple of nights before you travel down, take it gently on day one, and the trip to Machu Picchu becomes a descent in every sense.

Which route suits you — and what to avoid

If you take only one thing from this guide, make it the booking order: secure the timed entry ticket before anything else, because the train, the bus and your night below the mountain are all built around that slot. With the ticket fixed, the route almost chooses itself from your time, budget and appetite for walking.

• Short on time, want comfort: train from Ollantaytambo, with a night in the Sacred Valley or Aguas Calientes. The default, and the right one for most.
• Want the arrival earned: a trek — the Inca Trail if you can book months ahead and want the Sun Gate, the Salkantay or Lares otherwise.
• Tight budget, time to spare: the Hidroeléctrica route in the dry season, with a buffer day.
• Avoid: arriving in Cusco and going straight down the same day with no acclimatisation buffer; cutting the gap between train and entry slot too fine; and the Hidroeléctrica road in the wet season if your schedule has no slack.
