Cusco sits at about 3,400m (11,200ft) above sea level, which puts it among the highest cities most travellers will ever visit. First-time visitors feel it. Understanding what the altitude does to your body makes the trip considerably more comfortable.
Altitude sickness is the standard problem — headaches, nausea, fatigue — and it hits anyone flying in directly from sea level. The fix is boring but effective: slow the first day right down, stay hydrated, skip strenuous activity. Coca tea is a local staple that genuinely helps.
Once you adjust, the altitude is the attraction. Thin, clear air gives Cusco its sharp light, long shadows and famous sunrises over the surrounding peaks. Cold nights, warm days, almost no humidity — ideal for walking the Inca stonework around the Plaza de Armas and the ridge sites above the city.
For packaged tours that pace Cusco and the Sacred Valley around the altitude, Peruways builds itineraries that keep demanding activities for days three and four rather than day one.
Plan around the elevation and Cusco opens up. Push it on day one and you’ll pay for it.
