Machu Picchu: The Logistics Most Guides Get Wrong
Most travel articles about Machu Picchu misidentify which altitude will affect you. The ruins sit at 2,430 metres above sea level — a moderate elevation that rarely causes problems. Cusco, where almost every visitor spends two to three days before heading to the site, sits at 3,400 metres. That 970-metre difference matters. The standard itinerary actually works in your favour: you acclimatise in Cusco, then descend to Machu Picchu, gaining relief rather than facing additional altitude stress. Plan your trip around Cusco's elevation, not the ruins'.
