How long does altitude sickness last in Cusco?

Most people feel better within 48-72 hours if they take it easy. Mild headaches and fatigue are normal for the first day or two. If symptoms worsen after 48 hours or include confusion, vomiting, or severe headaches, descend immediately.

Should I take altitude sickness medication?

Diamox (acetazolamide) can help but requires a prescription and has side effects. Try natural adjustment first unless you have a history of severe altitude sickness. Many people do fine with coca tea, rest, and hydration.

Can I exercise or hike my first day in Cusco?

No. Even walking up stairs will wind you. Save Rainbow Mountain, the Inca Trail, or any day hikes for day 3 or later. Your first day should be sitting in cafes and gentle walking around the city center.

Is it better to arrive in Cusco from Lima or from another high city?

Coming from sea level (Lima) to 11,200 feet is a shock. If possible, spend a night in Arequipa (7,600 feet) or take the train from Lima through progressively higher elevations. But most people fly direct and adjust fine with proper preparation.

How to Adjust to Altitude in Cusco Quickly

Start altitude adjustment before you arrive by staying hydrated and avoiding alcohol. In Cusco, take it slow for 24-48 hours, drink coca tea, and stay at lower elevations when possible. Most people adapt within 2-3 days with proper preparation.

Start preparing 3 days before arrival. Increase water intake to 3-4 liters daily and cut alcohol completely. If you have access to altitude training or can spend time above 8,000 feet beforehand, do it. Consider taking iron supplements if you're low on iron.
Choose your arrival strategy. Fly into Lima first, then take the train to Cusco (gradual ascent) rather than flying directly to Cusco if you're altitude-sensitive. If you must fly direct, plan to stay put for your first full day.
Take the first 24 hours slowly. No hiking, no heavy meals, no alcohol. Walk slowly around San Blas or the main plaza. Sit in cafes. Your only job today is existing at 11,200 feet without stress.
Drink coca tea constantly. Order mate de coca at every cafe and restaurant. It's not just cultural - the mild stimulant genuinely helps with altitude symptoms. Drink 4-6 cups throughout the day, starting when you wake up.
Sleep smart. Book accommodation in San Blas neighborhood (slightly lower than the main plaza). Use an extra pillow to keep your head elevated. Many hotels have oxygen concentrators available - ask at check-in.
Know when to descend. If you have severe headaches, nausea, or confusion after 48 hours, go to lower elevation immediately. The train to Ollantaytambo (9,200 feet) runs daily and can provide relief within 2 hours.
