Lower oxygen levels, and a high probability of not being able to reach the summit on foot, yes, Rainbow Mountain, or Vinicunca as it's officially known, is a difficult hike, to say the least.
You have been warned.
Vinicunca's altitude stands at 5200 meters above sea level. For a better understanding of how big that really is for people that live in Europe, it's taller than Mont Blanc (the highest mountain in the Alps and western Europe) which stands at 4809 meters above sea level. If you have been to the summit of Mont Blanc you know your breathing can be affected and rightly so as the oxygen is 30% less than at the base.
For those of you that haven't, be prepared for a lack of oxygen. In fact, on our trek up Rainbow Mountain, we brought an oxygen canister just in case, luckily we did it because I definitely needed it.
Hiking will test your breathing as it is, take away 30% or more oxygen from an already difficult task and you will feel the effects tenfold.
Amazon has a selection of portable oxygen tanks in case you are not able to find one yourself.
For you gym goers that means a tougher time, a study found the more muscle you have the more oxygen you will need when exercising (Click here to read more on this subject) another word of warning, do not try to keep up with your *ahem*, less muscular friends, plus its a great excuse to go slower if you wish. In fact, the slower you go the more argument you can have for being bigger than your friends, right?
Anyway, that's enough boasting, if you have read my other hiking experiences then you will realise that I tend to do things a little unprepared. This was the first mountain I had ever hiked so it was no different here.
