ALTITUDE SICKNESS
How to handle altitude sickness when flying from Lima to Cusco
Flying from Lima (sea level) to Cusco (3,400 m / 11,150 ft) is one of the most breathtaking transitions you’ll ever make. In just over an hour, you go from the Pacific coast to the heart of the Andes. For most people, the change is smooth, but the sudden jump in altitude can cause mild symptoms known as altitude sickness. Don’t worry—millions of travelers visit Cusco every year and enjoy their trip fully. With a few easy steps, you can adjust comfortably and make the most of your adventure.
What Altitude Sickness in Cusco Feels Like
Most travelers arriving in Cusco notice only mild and temporary effects:
Shortness of breath when climbing stairs or hills
Slight fatigue or lightheadedness
A dull headache or restless sleep the first night
These are normal as your body adapts to the thinner air. Symptoms usually ease within 24–48 hours. Serious cases are very rare if you take things easy.
Tips to Prevent Altitude Sickness in Cusco
Here are some traveler-tested ways to feel your best:
1. Take it slow on arrival
Your first day in Cusco should be relaxed. Stroll the Plaza de Armas, enjoy a coffee, or wander the cobblestone streets at an easy pace. Avoid rushing straight into tours or treks.
2. Stay hydrated
The air at altitude is dry, so sip water regularly. Herbal teas are popular—don’t miss mate de coca, a traditional Andean tea that locals recommend for adaptation.
3. Go light on food and alcohol
Rich, heavy meals and alcohol can make you feel worse at altitude. Opt for light Andean soups, quinoa dishes, and vegetables for your first meals. Save your celebratory pisco sour for a couple of days later.
4. Consider sleeping lower in the Sacred Valley
If your itinerary allows, spend your first night or two in the Sacred Valley (around 2,800 m / 9,200 ft). It’s lower than Cusco, making acclimatization gentler, and offers incredible scenery and culture.
5. Give your body time before trekking
Planning the Inca Trail or Salkantay trek? Build in 2–3 days in Cusco or the Sacred Valley before starting. You’ll acclimatize better and enjoy the trek far more.
Local Support in Cusco
Cusco is well-prepared for altitude travelers. Many hotels keep oxygen on hand for guests, pharmacies carry remedies, and guides are used to helping visitors adjust. Coca tea, coca leaves, and other natural options are widely available.
Should You Be Concerned?
The majority of travelers only feel mild discomfort, if anything at all. With rest, light meals, hydration, and a relaxed pace, your body will adapt. Remember, Cusco welcomes everyone—from backpackers to grandparents—who safely enjoy this incredible city every year.
