In general, Chile is a relatively safe country. In my 3 1/2 years living there, I only had one attempt to rob me, and that was because I came out of a nightclub while drunk at 5 o'clock in the morning. Just the slightest bit of common sense and you shouldn't have any problems.
Do take precaution however while downtown. I do know many people who hve been robbed while walking downtown. Put your wallet in you front pocket and your daypack in front of you. Bag slashers are not uncommon.
One of the biggest problem in Santiago is SMOG, this city is one of the most contaminated cities in the world, competes with Mexico City and Sao Paulo for the ignominious title of Latin America's most polluted city.
Worst months for pollution are April to June.
Streets and roads are very good condition in Santiago city. Thats a good thing, but they drive very fast even in city centre. So, watch out.
the steps of Cerro Santa Lucia are an adventure by themselves : worn out, slippery but also worth going, just be extra careful !

This is the main avenue of Santiago (Avenida Libertador O'Higgins) at 7 in the evening.It causes stress.
There are some homeless dogs in Santiago but they are very docile and just looking for a new home. They are not vicious or likly to bite.
Protect your self from the sun (use a sunblock 15 to 40), take it serious, when walking the street, the sun is very strong and without noticing it you can be burned and spent bad time
