Does this 11-day Peru + Ecuador itinerary make sense? (Altitude optimized)

Hey all — would love a sanity check on this itinerary. Tried to optimize for altitude acclimation while still moving efficiently. I’m a pretty aggressive traveler and enjoy hiking, but don’t want to completely burn out.

🇵🇪 Peru — 8 Days

Day 1: NYC → Lima (Miraflores/Barranco)
Day 2: Lima (easy culture + food day, sea level acclimation)

Day 3: Lima → Cusco → Ollantaytambo (straight to Sacred Valley)
Day 4: Sacred Valley (Pisac, Maras Salt Mines, Ollantaytambo — keeping it light)

Day 5: Machu Picchu (main event, optional Sun Gate or Huayna Picchu) → Cusco
Day 6: Cusco (recovery + light exploring: ruins, San Blas, cafes)

Day 7: Rainbow Mountain (early hike, full rest after, no flights)
Day 8: Cusco → Lima → Quito

🇪🇨 Ecuador — 3 Days

Day 9: Quito Old Town (historic center, food, cable car if weather is good)
Day 10: Cotopaxi National Park day trip
Day 11: Fly home

Key thinking:

• Built in acclimation (Sacred Valley before Cusco)
• No travel same day as Rainbow Mountain
• Trying to balance efficiency + not feeling rushed

Questions:

1. Is Rainbow Mountain too much after Machu Picchu + Cusco? (I’m open to cutting it if it’s overkill)
2. Is 2 nights Sacred Valley enough before MP?
3. Is Cotopaxi worth it for such a short Ecuador leg?
