Quick answer: Plan 3–4 days around Cusco — including acclimatisation and a Machu Picchu visit.
Cusco sits at 3,400m, so build in time to adjust before trekking.
How many days, by trip type
2 days
Acclimatise in Cusco and explore the city and nearby ruins.
3–4 days (ideal)
Add the Sacred Valley and a Machu Picchu day or overnight.
5–7 days
The Inca Trail or Salkantay trek to Machu Picchu.
The ideal length
Give yourself 3–4 days minimum, with the first day or two for altitude. Add several more for a trek.
How many days do you need in Cusco?
Three to four days minimum for Cusco — and crucially, you need the first day or two just to acclimatize to the 3,400m altitude before Machu Picchu. Add more for the Inca Trail or extra Sacred Valley time.
Suggested plan
- Day 1: Arrive and rest — gentle wander of the Plaza de Armas and San Blas; hydrate, go easy.
- Day 2: Sacred Valley — Pisac market and Ollantaytambo (lower altitude helps).
- Day 3: Machu Picchu (train from Ollantaytambo).
- Day 4: Cusco sights — Sacsayhuamán, the Qorikancha, and the San Pedro market.
If hiking the Inca Trail (4 days), add it to the front and arrive in Cusco several days early to acclimatize.
