Is coca tea actually effective?

Yes, it is the standard local remedy. It is mild, helps with the headache, and is widely available at every hotel in the region.

Do I need an oxygen tank?

Most hotels in Cusco provide supplemental oxygen canisters or dedicated oxygenated rooms. You shouldn't need a portable tank unless you have pre-existing respiratory conditions.

Planning Your Trip to Machu Picchu Without Getting Altitude Sickness

To avoid altitude sickness, spend your first 2-3 nights in Cusco (3,400m) or the Sacred Valley (2,800m) before hiking or taking the train to Machu Picchu. Drink coca tea, stay hydrated with 3 liters of water daily, and avoid strenuous exercise for the first 48 hours.

Start in the Sacred Valley. Fly into Cusco but immediately take a private car or shuttle down to towns like Urubamba or Ollantaytambo. They sit at a lower altitude (approx. 2,800m) than Cusco, allowing your body to adjust more gently.
Spend 48 hours acclimatizing. Do not book your Machu Picchu entry or a strenuous hike for the day you arrive. Dedicate two full days to walking slowly, resting, and drinking plenty of water.
Manage your energy. Avoid heavy meals and alcohol for the first 3 days. Digestion slows down at high altitudes, and alcohol exacerbates dehydration and fatigue.
Consult your doctor for prophylaxis. Ask your doctor about Acetazolamide (Diamox). Start taking it 24 hours before arriving at high altitude if you have a history of altitude sickness.
