Dangers & Annoyances
Take it easy at first: the park's altitude is mostly well above 4000m and overexertion is a big no-no until you've had a few days to adapt. Eat and drink moderately; have mainly light food and no fizzy drinks or (little) alcohol. If you suffer anyway, try a cup of tea made from the common Aymara herbal remedy chachacoma, rica rica or mate de coca. Keep water at your side, as the throat desiccates rapidly in the arid climate and you lose lots of liquids. Definitely wear sunblock and a wide-brim hat – tropical rays are brutal at this elevation.
