Comments on: How To Avoid Altitude Sickness In Cusco And Machu Picchu And On The Inca Trail https://www.machupicchutrek.net/altitude-sickness/ Machu Picchu and Inca Trail Trek Information Mon, 15 Jun 2026 14:28:25 +0000 hourly 1 By: Dee https://www.machupicchutrek.net/altitude-sickness/#comment-31033 Thu, 28 May 2026 08:01:04 +0000 https://www.machupicchutrek.net/?p=3985#comment-31033 Thanks for the useful info Mark! I am tight on time as I'm with a tour group, and breaking away for 1 day to do Rainbow Mts. I will fly into Cusco and drive to Sacred Valley to spend 2N there. Then 1N in Machu Picchu, before driving back to Cusco. Estimated arrival in Cusco 5pm, and having just 1/2 night sleep before 3AM pick-up to Rainbow Mountains. Is this sufficient acclimatizing, given I have 2N in Sacred Valley but just 1/2N in Cusco before the 3AM pick up? I have no other choice as I need to rejoin my tour group and depart Cusco the day after. It's my one shot at seeing Rainbow Mt.

Appreciate your thoughts. I'm excited at the prospect of seeing Rainbow Mt but am concerned about not acclimating sufficiently. Thanks!
