How to prepare for Machu Picchu altitude

Altitude sickness happens when the body struggles to cope with the reduction of oxygen at high altitude. Everyone reacts differently to altitude, but common symptoms include fatigue, headache, nausea, dizziness and swelling. Symptoms usually subside or disappear after a couple of days, but may take longer in severe cases.

We recommend seeing your doctor if you have any health concerns before undertaking a trip to Machu Picchu, particularly if you have a pre-existing medical condition or are taking any medication.

While it might not be possible to avoid altitude sickness completely, there are some general recommendations to prevent it:

• Spend a few days in Cusco beforehand – Cusco is located at a higher altitude than Machu Picchu and can be a good place to acclimatize
• Take it easy on the days leading up to the trek
• Avoid alcohol before and during the trek – as tempting as those pisco sours may be, it’s not worth it
• Drink plenty of water while hiking – half a liter is recommended for every hour of hiking
• Don't forget to take long, slow, and deep breaths every now and then to help increase blood oxygen levels
• Carry altitude sickness tablets with you

If you feel unwell, locals might offer you a cup of mate de coca (a tea made with coca plant leaves). This herbal beverage tastes a bit like green tea and has a mild stimulating effect similar to coffee. It's drunk by locals all over the Andes region and is hailed for its healing properties.

If you’re really worried about altitude sickness, you could stay in Urubamba to acclimatize before the trek to Machu Picchu, which is lower than Cusco at 2871 meters above sea level.
