Warning signs: get help
Seek medical help immediately and descend if you notice confusion, loss of coordination, extreme drowsiness, breathlessness at rest, a persistent cough, or a severe headache that doesn’t improve. These can be signs of serious altitude illness. Cusco has clinics experienced with altitude problems, and most hotels can provide oxygen while you wait.
How to acclimatise
- Sleep low first: spend your first 1–2 nights in the Sacred Valley, then go up to Cusco. See our Cusco itinerary.
- Slow down: walk slowly, especially uphill and on stairs, and rest on day one.
- Drink water and limit alcohol for the first 48 hours.
- Eat light meals, rich in carbohydrates.
- Save big hikes such as Rainbow Mountain for the end of your trip.
Coca tea and local remedies
Mate de coca (coca leaf tea) is offered everywhere in Cusco and many people find it helps with mild symptoms. Note that it can show up in drug tests, and you shouldn’t take coca leaves home: they are illegal in many countries.
Medication
Some travellers take prescription medication such as acetazolamide to help prevent altitude sickness. It isn’t suitable for everyone, so discuss it with your doctor before travelling. Over-the-counter painkillers can help with mild headaches.
Choosing hotels
Many Cusco hotels offer oxygen-enriched rooms or oxygen on request. Avoid hilltop neighbourhoods with lots of stairs for your first nights. See where to stay in Cusco.
