Reaching Machu Picchu on foot isn't a single experience—it's a menu of treks varying in difficulty, scenery, cultural immersion, and logistics. All require altitude acclimatization (Cusco at 3,400m/11,150ft is the typical base). Here's how the main routes compare.
The iconic route. Permits limited (500/day including guides/porters) — book 6+ months ahead. Highlights: Inca ruins en route (Llactapata, Runkurakay, Sayacmarca, Phuyupatamarca), cloud forest, Dead Woman's Pass (4,200m/13,780ft — highest point), Sun Gate (Inti Punku) sunrise arrival at Machu Picchu. Requires good fitness; porters carry gear; camping in designated sites.
Popular alternative, no permit lottery. Higher peak: Salkantay Pass (4,630m/15,190ft). More diverse landscapes: glacial valleys, tropical forest, coffee plantations. Less archaeological density but spectacular mountain scenery. More camping options; some operators offer lodge-based versions. Better availability.
Cultural focus: visits Quechua weaving communities, hot springs, fewer tourists. Lower max elevation (~4,000m/13,123ft). Less strenuous overall but still multi-day altitude hiking. Often combined with short Inca Trail segment or train from Ollantaytambo. Good for cultural immersion seekers.
To the "other Machu Picchu"—Choquequirao, a massive, partially excavated Inca site receiving <1% of Machu Picchu's visitors. Steep, repetitive ascents/descents (Apurimac Canyon 1,500m/4,900ft depth). Remote, minimal infrastructure. Requires experience, fitness, self-sufficiency. Can extend to Machu Picchu (8–9 days total).
Adventure hybrid: mountain biking (downhill from 4,300m), hiking, zip-lining, optional rafting. Less pure trekking; more varied activities. Difficulty varies by activity mix. Ends with train to Aguas Calientes + Machu Picchu visit. Appeals to adrenaline-focused travelers.
Acclimatize: Spend 2–3 days in Cusco/Sacred Valley before starting. Hydrate: 3–4L water daily. Ascend gradually: "Climb high, sleep low" when possible. Recognize AMS: Headache, nausea, dizziness = descend immediately. Choose reputable operator: Licensed, fair porter treatment, safety protocols. Train specifically: Stair climbing, weighted pack hikes, cardio 3+ months prior.
