Cusco travel guide 2026: altitude, Machu Picchu tickets and itinerary

Cusco is both a destination and a gateway, and planning it well means respecting two things: the altitude, which affects almost everyone to some degree, and the Machu Picchu ticketing system, which became considerably stricter for 2026. Handle those and the rest is one of the most rewarding city bases in South America. This guide covers acclimatisation, tickets, seasons and a 4-day plan.

Altitude comes first

Cusco sits at roughly 3,400 metres, which is high enough that most visitors feel it: headaches, breathlessness on stairs, poor sleep and reduced appetite in the first day or two. This is normal and usually passes, but it shapes how you should structure the start of a trip.

The standard approach is to arrive and do very little. Walk slowly, eat lightly, avoid alcohol on the first night and drink more water than usual. Coca tea is offered everywhere and many find it helps. Do not schedule a demanding hike or a high pass on day one or two.

A useful detail: much of the Sacred Valley sits lower than Cusco, around 2,800 metres, and Machu Picchu lower still at about 2,400 metres. Some travellers now head straight to the valley on arrival and acclimatise there, returning to Cusco later, which is gentler than starting at the highest point.

Machu Picchu tickets in 2026

The old system of booking whenever you liked is gone. Peru's Ministry of Culture now releases tickets on a phased calendar, capacity is capped at 4,500 visitors most days and up to 5,600 on selected high-season dates, and prime circuits sell out quickly after release.

Tickets are tied to a specific circuit chosen at booking, and the routes are one-way with no deviation permitted. Once confirmed, tickets generally cannot be changed, cancelled or refunded, so your date needs to be settled before you buy.

Book as far ahead as you can, and treat 60 days as a sensible minimum in high season. Train seats to Aguas Calientes need booking separately and also sell out, so secure the entry ticket first and then match the train to it.

When to visit Cusco

The dry season from May to September brings the clearest skies and the best trekking conditions, and it is peak season. June to August is busiest, and the Inti Raymi festival in late June fills the city.

The wet season from November to March brings afternoon rain and cloud, though mornings are often clear and prices and crowds drop substantially. The Inca Trail closes each February for maintenance, which is worth knowing if a trek is your goal. April, May, September and October are the shoulder months that balance weather against crowds.

Where to stay

The historic centre around the Plaza de Armas is the convenient choice, walkable to the main sights and where most tours depart. San Blas, uphill from the centre, is the artisan quarter with cafés and views, atmospheric but a steeper walk home, which matters more than usual at this altitude.

Example 4-day Cusco itinerary

Prompt idea: "4-day Cusco itinerary in 2026, first-time visitor, include acclimatisation days, city sights and one Sacred Valley day."

• Day 1 - Arrival and rest: a gentle walk around the Plaza de Armas, light meal, early night.
• Day 2 - City sights: the cathedral, Qorikancha, and Sacsayhuamán just above the city.
• Day 3 - Sacred Valley: Pisac market and ruins, Ollantaytambo, valley viewpoints.
• Day 4 - Spare day or onward: a second valley day, Rainbow Mountain if acclimatised, or the train toward Machu Picchu.

FAQs

How bad is the altitude in Cusco?

Most visitors feel something in the first 48 hours: breathlessness, headache and disturbed sleep are common. It usually passes with rest, hydration and a slow start. Anyone with heart or lung conditions should get medical advice before travelling.

How many days should I spend in Cusco before Machu Picchu?

At least two nights at altitude before any strenuous activity, and more before a trek. Some travellers instead acclimatise in the lower Sacred Valley first, which is a gentler introduction.

How far ahead do I need to book Machu Picchu?

As far as possible, and at least 60 days in high season. Tickets are released on a phased calendar, capacity is capped, popular circuits sell out fast, and confirmed tickets cannot normally be changed or refunded.

Do I need to choose a circuit when booking?

Yes. Your ticket is tied to a specific one-way route and rangers enforce it. Read the circuit descriptions before booking, since they cover different parts of the site and not all include the classic postcard viewpoint.

Should I bring cash?

Yes, in soles. Markets, small restaurants, taxis and many artisan shops are cash-only, while hotels and larger restaurants take cards.

Is Cusco safe?

Central Cusco is generally safe. Standard precautions apply at night and in crowded markets, and it is worth using registered taxis or ride-hailing rather than hailing on the street late in the evening.
