While in Lima I stay in the Miraflores area, which is very nice and safe. I often see lots of young Americans and Europeans. I've also seen some very poor areas of Lima where I wouldn't dare consider venturing outside of my car.Like in most areas of the world, common sense is your best defense. know that Peru isn't one of THE most dangerous countries in South America, but I've spent my life in rural America, so I'm not quite in-tune with my street smarts.
