At this high elevation, locals frequently apply, and reapply, effective sunscreen, and it’s good to note that one alcoholic drink equals three—so tread lightly on those delicious margaritas and specialty beers. For those who have trouble adjusting to altitude, a massage catering to what ails is helpful, as is the locally produced ChlorOxygen, a chlorophyll herbal remedy that purports to increase your blood’s capacity to hold oxygen. And, in the food category, locals eat the fluffy fried pastries (known as sopapillas) after their meal.
