I am visiting Bogota for the first time next week and am unsure how prepared I need to be for cold weather due to the altitude. Do I need a down jacket and hat or are sweaters and light jackets enough? I don't want to drag around heavy cloths i don't need but don't want to be cold either.
Also, I plan to get most of my money out of ATMs locally but is there any advantage to bringing US dollars?
Thanks for the insight.
