Cusco was the capital of the Inca Empire. Today it is the base for Machu Picchu and the Sacred Valley. Its historic centre is a UNESCO World Heritage Site, where Spanish colonial churches stand on Inca stone foundations.

Altitude first

Cusco sits at about 3,400 m above sea level. Many visitors flying in from Lima feel headaches, breathlessness or poor sleep on the first day or two. Common advice:

• Keep your first day light. Walk slowly and drink water.
• Go easy on alcohol at first.
• Some travellers start in the lower Sacred Valley (about 2,800–2,900 m) and come up to Cusco afterwards.
• Talk to a doctor before the trip about prevention, especially if you have heart or lung conditions. Severe symptoms need medical attention and a move to lower altitude.

What to see

• Plaza de Armas and the Cathedral.
• Qorikancha, the Inca sun temple, with the Santo Domingo convent built on top of it.
• San Blas, the hilly artisans' quarter with steep lanes and viewpoints.
• Sacsayhuamán, the fortress above town with huge fitted stones. The Inti Raymi festival is staged here every June.
• San Pedro Market for local food and juices.

Many sites around Cusco are covered by the regional tourist ticket (boleto turístico). Check which sites it includes before buying separate entries.

Getting in and around

Cusco's airport (CUZ) has frequent flights from Lima. Compare routes on Search flights (partner). The centre is compact and walkable but steep. For the airport run, a pre-booked transfer avoids haggling on arrival: Kiwitaxi (partner).

Day trips

Popular trips include the Sacred Valley (Pisac, Ollantaytambo, Moray, Maras salt pans), Rainbow Mountain (which goes above 5,000 m) and of course Machu Picchu. Compare guided options on Klook (partner). If you prefer exploring at your own pace, self-guided audio tours are on WeGoTrip (partner).

Where to stay

• Around the Plaza de Armas: the most central, and flat by Cusco standards. You can walk to most sights and restaurants.
• San Blas: charming and quieter, but uphill. Climbing back to your room at altitude is noticeable on day one.
• San Pedro and the area near the market: more local, and close to the train station for Machu Picchu services from the city.

Rooms in old colonial buildings can be cold at night. Check for heating, and expect thick blankets rather than central heating in cheaper places.

A first three days

Day 1: Arrive, rest and take a short walk around the plaza. Eat lightly. Many hotels offer coca tea, a traditional local remedy.

Day 2: Visit Qorikancha and the Cathedral in the morning, then San Blas and San Pedro Market.

Day 3: Walk or ride up to Sacsayhuamán, and nearby sites such as Q'enqo if your ticket includes them. Or head down into the Sacred Valley.

Weather and seasons

The dry season, roughly May to September, brings clear days and cold nights, sometimes near freezing. It is also the busiest time. The wet season, roughly November to March, is greener, with afternoon rain. Sun at this altitude is strong year-round, so bring sunscreen and a hat even when it feels cool.

Practical notes

• Use registered taxis or app-booked rides at night, especially from the bus terminal.
• Carry small change for markets and site entries.
• Tap water is generally not recommended for drinking. Use bottled or filtered water.
• Ask before photographing people in traditional dress. Some expect a tip for photos.

Eating, drinking and sleeping at altitude

Your first evening in Cusco sets the tone for the trip. Eat lightly, drink plenty of water, and go easy on alcohol for the first day or two, as altitude can amplify its effects. Coca tea (mate de coca) is offered almost everywhere as a traditional remedy. Some travellers find it helps, but it isn't a substitute for acclimatisation, and it can show up in drug tests. Sleep can be restless at first, which is normal. If your hotel offers a room on a lower floor, it saves climbing stairs while you adjust. Keep strenuous activities such as Rainbow Mountain or long treks for later in your stay, after you've had a couple of easy days in town or in the lower Sacred Valley.

Checklist

• Talk to a doctor before the trip if you have heart or lung conditions, or if you're considering altitude medication.
• Schedule your first day as a rest day with only gentle walking.
• Carry a refillable water bottle and sunscreen, as the sun is strong at altitude.
• Buy the Boleto Turístico only if your plans cover enough of its sites.
• Keep a copy of your passport and insurance details on your phone.

FAQ

How long does it take to acclimatise?

It varies by person. Many feel better after one to three days, but some people take longer.
