Altitude affects each person differently. Some travelers feel only mild tiredness, while others may experience headache, nausea, dizziness, poor sleep or shortness of breath.

Important safety note

Strong headache, vomiting, confusion, chest pain or severe breathing difficulty should not be ignored. If symptoms become serious, seek medical help and do not continue to higher-altitude tours.

Dizziness

How Many Days Do You Need to Acclimate in Cusco?

Most travelers should spend at least one or two easy days in Cusco before doing demanding high-altitude activities. If your itinerary includes Rainbow Mountain, Humantay Lake, Salkantay, Ausangate or a long trek, it is better to acclimatize first.

A good first plan is to walk slowly around the historic center, visit San Pedro Market, do a light Cusco City Tour or explore the Sacred Valley before attempting harder routes.

What Should You Do on Your First Day in Cusco?

Your first day in Cusco should be simple. Rest, drink water, eat light food and avoid alcohol. Choose easy activities instead of difficult hikes.

Walk slowly around the Plaza de Armas.
Visit San Pedro Market.
Explore Qorikancha or San Blas at a relaxed pace.
Drink water regularly.
Eat light meals.
Sleep early before your next tour.

Cusco Altitude vs Machu Picchu Altitude

Many travelers think Machu Picchu is higher than Cusco, but it is actually lower. Cusco is around 3,399 meters / 11,152 feet, while Machu Picchu is around 2,430 meters / 7,972 feet.

This means many visitors feel the altitude more strongly in Cusco than at Machu Picchu. However, Machu Picchu still requires walking, stairs and sun protection.

How to Prevent Altitude Sickness in Cusco

Plan an easy first day after arrival.
Drink water regularly.
Avoid alcohol during the first 24 hours.
Eat light meals before demanding tours.
Walk slowly, especially uphill.
Sleep well before high-altitude hikes.
Ask a doctor about medication if you have previous altitude problems.

Recommended Easy Tours for Your First Days in Cusco

If you are still adapting to the altitude, choose cultural tours near the city before attempting demanding hikes. The Cusco City Tour, South Valley Tour and Sacred Valley are better first steps than Rainbow Mountain or long treks.
