Arriving in Cusco is exciting — but the altitude can hit harder than most people expect. At 3,400 meters (11,150 ft), your body needs time to adjust.
Most travelers experience mild symptoms within the first 24 hours. This can include headaches, shortness of breath, fatigue, and sometimes nausea.
It’s not dangerous in most cases — but it can definitely ruin your first day if you don’t prepare.
One of the best ways to adapt is actually to walk slowly around the city instead of staying in bed all day. A relaxed walking tour helps your body adjust naturally.
