How to avoid altitude sickness in Cusco and Puno.

For many travelers, going to Cusco and Puno is a big wish come true — with old Inca temples, lively markets, and the stunning Lake Titicaca. However, these places are located high up in the Andes. Cusco is 3,400 meters (11,150 feet) high, and Puno is even higher at 3,800 meters (12,500 feet). The change in height can lead to a problem called altitude sickness or soroche.

The good news is that there are easy ways to get your body ready and stop symptoms like headaches, feeling sick, and tiredness, so you can enjoy your trip in Peru fully.

1. Get Used to the Altitude Slowly

If you can, spend the first one to two days in a city that isn’t as high, like Arequipa (2,335 meters) or the Sacred Valley (2,800 meters), before going to Cusco or Puno. This helps your body get used to the thinner air before you go higher, which makes it less likely for you to get altitude sickness.

2. Drink Lots of Water and Eat Light Meals

Make sure to drink enough water throughout the day since not having enough can make altitude symptoms worse. Try to stay away from big meals, too much caffeine, and alcohol for the first 24 hours when you are up high. Instead, eat light foods like soups, fruits, and drink herbal teas so you can keep your energy up.

3. Consider Coca Tea or Local Treatments

Coca tea (mate de coca) has been used in the Andes for a long time to help with altitude effects. You can find it in almost all hotels and restaurants in Cusco and Puno. Other good options include muña tea (Andean mint) or oxygen supplements that you can get at pharmacies.

4. Take Your Time and Rest Frequently

Hiking up hills or going up stairs can be more tiring when you’re at a high place. Move at a slow pace, especially on your first day. Don’t hurry to see all the sights – your body needs time to get used to the elevation. Take breaks often, and stay away from heavy activities like long hikes until you’re feeling settled in.

5. Think About Medicine (If Necessary)

If you know that you have a hard time with high places or have felt sick before, talk to your doctor about taking acetazolamide (Diamox). This medicine can help your body get used to the altitude more quickly. Make sure to take it as your doctor advises, starting a day before you go higher up.

6. Pick Hotels That Offer Oxygen Help

Several hotels in places like Cusco and Puno provide services for people visiting high altitudes, such as oxygen tanks or rooms with extra oxygen. When making your reservation, check for these features – they can be very helpful, especially for your first night.

7. Pay Attention to How You Feel

The best way to avoid getting sick from altitude is to listen to your body’s signals. If you start to feel dizzy, really tired, or struggle to breathe, stop and rest right away. Most times, just getting some sleep or drinking water can help. If the problems continue or get worse, head down to a lower altitude and get medical assistance.
