If Peru is in your plans with children, route order matters more than almost anything else. We learned this from Cotopaxi-style high-altitude days where energy could shift quickly.
Recommended Sequence (7-10 Days), Based On Our Experience
- Days 1-3: Sacred Valley base first. The valley sits lower than Cusco and gives your body time to adjust before going higher.
- Days 4-5: Cusco with one real activity per day. Avoid stacking sites and stairs-heavy visits.
- Days 6-7: Only schedule your hardest day after everyone has stable sleep and appetite for at least two days.
- Buffer days: Keep 1-2 open days; our own best decisions came from not forcing the original plan.
Daily Rules That Helped Us
- No arrival-day tour bookings at altitude.
- One physically demanding block per day maximum.
- Treat "a bit off" as a warning sign. We consistently got better outcomes when we slowed down early.
If One Child Is Hit Harder
Plan every high-altitude day with split options so one adult can stay back if needed. On one of our high-altitude days, one child stayed back while the others continued a glacier route, and that flexibility prevented the whole day from being lost.
