Machu Picchu sits at 2,430 meters (7,970 feet) — high, but not the real altitude challenge of the trip. The city that catches people out is Cusco at 3,400m (11,152 feet), where almost every Machu Picchu itinerary starts. Acute Mountain Sickness is common in the first 24 hours there, and Peruways routes most first-timers through the Sacred Valley at 2,800m specifically to soften the arrival.
The reliable countermeasure is time. Two to three nights above 2,500m before heading up to the citadel. Cusco works; the Sacred Valley works better because the sleeping altitude is lower. Avoid the common mistake of flying in and heading straight to Rainbow Mountain at 5,200m on day 2 — that one hurts.
Hydration is the second lever. Three to four litres a day at altitude, no alcohol in the first 48 hours, light meals. Caffeine is fine; it’s not actually a dehydrator at the doses most people drink.
Pace day 1. Slow walks, no stairs taken at speed, early night. Day 3 at altitude is usually when the body has settled. Coca tea (mate de coca) is a mild vasodilator and genuinely helps; acetazolamide (Diamox) is the pharmaceutical option if symptoms are severe.
Peruways’ guides are trained to spot AMS and to adjust the day’s pace accordingly. For high-altitude add-ons like Huayna Picchu or Rainbow Mountain, we build in rest days.
Plan the altitude layer at Peruways. The trip is a lot better from inside Machu Picchu than from inside a hotel room.
