Why this isn't a normal ticket
You can't hike it independently
The classic Inca Trail is not a trail you can walk on your own. Peruvian regulations require every trekker to go with a licensed operator, accompanied by a registered guide and porter team, on a permit issued in your name. There is no solo option and no way to buy your way onto the trail at the last minute — the guide-and-permit system is the whole model.
Permits are capped and sell out
Only around 500 permits are released per day for the classic Inca Trail — and because that total includes the guides and porters, the number of actual trekker spots is far smaller. For the popular dry-season months they sell out many months in advance. Permits are non-transferable, tied to your passport, and can't be topped up, so booking early through an operator is essential.
There are other ways in — and February is closed
If the classic four-day permits are gone, you're not out of options: there's a shorter two-day Inca Trail, the spectacular Salkantay trek that skirts the permit system, and the straightforward train-and-day-tour route to Machu Picchu. And every February the classic Inca Trail closes entirely for maintenance and conservation, so that month always means an alternative.
The main ways to reach Machu Picchu
The classic Inca Trail is only one route — and the hardest to get a permit for. Here's how the main options compare, from the four-day trail to the train.
| Route | What it is | Permit / booking |
|---|---|---|
| Classic Inca Trail | The famous 4-day trek over high passes to the Sun Gate | Capped permit, licensed operator, book months ahead |
| Short Inca Trail | A 2-day version walking the final stretch to the Sun Gate | Also permit-controlled; easier to secure |
| Salkantay trek | A longer, higher alternative around the permit system | No Inca Trail permit; still guided |
| Train + day tour | Rail to Aguas Calientes, then the citadel | No trek permit; entry ticket only |

The rule that shapes everything
Can you do the Inca Trail without a guide? No — here's how it works
The classic trail is permit-and-guide only. Understanding that is the key to planning it.

Read the guide →Questions people actually ask
Can you hike the Inca Trail without a guide?
No. The classic Inca Trail can only be walked with a licensed operator, accompanied by a registered guide and porter team, on a government permit issued in your name. Independent or solo hiking of the classic trail is not permitted. This is why every classic Inca Trail trip is a booked, guided package rather than something you arrange at the trailhead.
How far in advance do you need to book the Inca Trail?
For the classic four-day trail in the busy dry-season months, you should book several months ahead — often five or six, and sometimes more for peak dates. Only around 500 permits are issued per day (including guides and porters), they're tied to your passport, and once a day sells out there's no waitlist and no way to buy in at the last minute.
Is the Inca Trail ever closed?
Yes — the classic Inca Trail closes every February for maintenance and conservation, so no classic treks run that month. Machu Picchu itself stays open in February, reachable by train and day tour, and alternative treks like the Salkantay route continue, but the classic trail specifically is shut for the whole month.
What if the Inca Trail permits are sold out?
You have good alternatives. The shorter two-day Inca Trail covers the final, scenic stretch to the Sun Gate and is easier to secure; the Salkantay trek is a longer, higher and equally stunning route that doesn't use the Inca Trail permit system; and you can always reach Machu Picchu by train and a guided day tour. Many visitors happily end up on one of these.
How hard is the classic Inca Trail?
It's a challenging multi-day high-altitude trek. The route climbs over passes above 4,000 m — Dead Woman's Pass being the famous high point — with long days of walking on stone paths and steps. Fitness and acclimatisation matter far more than technical skill; most people spend a few days in Cusco beforehand to adjust to the altitude.
Do you need to acclimatise before the Inca Trail?
Strongly recommended. The trail reaches altitudes where the thin air affects almost everyone, so most trekkers arrive in Cusco (itself at high altitude) two or three days early to acclimatise before starting. Building in that buffer, staying hydrated and taking the first days gently makes an enormous difference to how the trek feels.
