Safety and infrastructure
Chile is a politically stable country with very few threats to the traveler. Chile is certainly one of the safest countries in Latin-American. Santiago and most Chilean cities are fairly safe. As in any city worldwide, there are some neighborhoods along the outskirts that are a little more dangerous and should be avoided at night. Travelers should take care of their belongings, especially around tourist areas and bus stations.
Healthcare in urban areas is adequate, but hospitals and clinics are extremely expensive and usually require payment in cash. Health insurance is strongly recommended.
