Can I go straight to Machu Picchu without stopping in Cusco?

Not recommended. While Machu Picchu is lower than Cusco, the train journey starts from Cusco or nearby. Most people need time to adjust before the physical demands of exploring the ruins.

Does physical fitness prevent altitude sickness?

No. Altitude sickness affects people regardless of fitness level. Even Olympic athletes can get severe symptoms. Gradual acclimatization is the only reliable prevention.

What if I get sick on the Inca Trail?

Porters can help evacuate you, but it takes time. This is why acclimatizing in Cusco first is crucial. Never start the Inca Trail if you're already experiencing altitude symptoms.

Is oxygen available if I need it?

Some hotels in Cusco have oxygen tanks available. Cusco airport and hospitals also have oxygen. However, if you need oxygen, you should consider descending rather than continuing to higher altitudes.

How to Handle Altitude Sickness in Cusco and Machu Picchu

Arrive in Cusco 2-3 days before visiting Machu Picchu to acclimatize gradually. Drink coca tea, stay hydrated, avoid alcohol, and take it easy your first day. If symptoms worsen beyond mild headaches and fatigue, descend to lower altitude immediately.

Plan your arrival timing. Fly into Cusco at least 2-3 days before your Machu Picchu trip. Cusco sits at 11,200 feet while Machu Picchu is at 7,900 feet. Use Cusco as your acclimatization base, not a quick stopover.
Take it slow on arrival day. Rest for 4-6 hours after landing. Walk slowly, avoid heavy meals, and skip any strenuous activities. Your body needs time to adjust to the reduced oxygen levels.
Drink coca tea immediately. Order coca tea (mate de coca) at your hotel or any café. Drink 2-3 cups throughout the day. It's a traditional remedy that genuinely helps with altitude adjustment and is completely legal in Peru.
Stay aggressively hydrated. Drink 3-4 liters of water daily. Altitude dehydrates you faster. Avoid alcohol for your first 48 hours as it worsens altitude sickness symptoms.
Recognize warning signs. Mild headaches, fatigue, and slight nausea are normal. Severe headaches, vomiting, confusion, or difficulty breathing mean you need to descend immediately. Don't tough it out.
Consider medication. Acetazolamide (Diamox) can help prevent altitude sickness. Take 125mg twice daily starting 24 hours before arrival. Consult your doctor before travel, especially if you have kidney issues or sulfa allergies.
