I have a TWO rules when our family is staying at Summit Peaks or Riverside Lodges, #1 drink lots of water and #2 Make sure you follow rule #1.
My rule of thumb is 8 liters of water a day or until ” your #1″ is clear! The Lodge sits at 9,245 feet above sea level and without proper hydration you are certain to have problems.
The other thing to bare in mind is avoid Diuretics, yes all the fun stuff…coffee, excessive alcohol, and even chocolate. (at least in the first days of acclimatization) This is serious stuff and is the MOST common problem I have heard of over the years from our guests. With simple prevention this can easily be avoided!
