Machu Picchu is as much a site of stairs as it is of stonework. The Incas carved paths and staircases directly into the mountain, linking temples, agricultural terraces, and residential zones across the ridge.
Expect uneven steps, variable rises, and short exposed sections. The most demanding climbs are the Sun Gate (Inti Punku) along the final stretch of the Inca Trail, and Huayna Picchu — a 60-minute ascent on narrow, cable-rail steps that opens onto a view down the length of the citadel. Both reward the effort.
Sturdy trail shoes and a litre of water are enough; acclimatise in Cusco for at least a day before you tackle anything strenuous at this altitude.
For a straightforward visit with tickets, transfers, and a guide handled for you, see Peruways. Peruways runs small-group tours and keeps the logistics out of your way so you can focus on the climb and the views.
