Acclimating to the altitude of Cusco
Arriving from a lower altitude to approximately 11,000 feet (3.4m) above sea level takes getting used to. Generally some of the effects of the altitude are fatigue and possibly a headache. Some people say that they also have had stomach aches. If you are concerned, speak with your doctor as to medications that can be used to ease the effects of the altitude. However, if you abide by the following suggestions you should be okay. On your first day or two in Cusco the best thing you can do is to rest and take it easy, drink plenty of water, and eat lightly. Drink coca tea, however not at night because it can act as a stimulant. Try to stay away from caffeinated items and alcohol.

Water bottles

Playing it safe
Though Cusco is generally a safe city, it is always best to take precautions. It is best to leave your valuables at home. Make a copy of your passport and have it legalized so that you can use the copy and leave the actual passport at your home-stay (this can be done at the language school). Leave a copy of your passport and other important documents at home. Keep your wallet and money in a front pocket, or inside jacket pocket; not a back pocket. In crowded areas keep your backpack in front of you. Be careful with your camera. At night stay away from isolated areas and travel around in small groups, not alone. If traveling by taxi, use only authorized taxis. Make sure you have your embassy’s information handy.
