The south is pretty much what you imagine about Scandinavia. We have 'regions' to divide the country, but are not states. From the sixth onwards starts the 'south', but you're talking about the most southern ones. From the 9th, you can see hundreds of lakes, rivers and snowy mountains, huge forests, a rather cold and fresh air. Most people lives in 1-floor houses, on the opposite of big cities that uses huge apartment buildings. A Good share of people lives working the land, a beautiful, yet sacrificed and heavy as hell lifestyle.
I've been into every known city from IV til X region. I've lived most of time in Valparaiso - V region, but I've been in cities like Rancagua, Talca, Curico, Osorno, Puerto Varas, Temuco, Puerto Montt, Concepcion, etx (just google images and you'll see).
Adventuring the more to the south, you'll notice that less people live there, leaving huge landscapes totally unexplored, the ice becomes more prominent until the point where it's the only thing you can see. The food is far better and healthier than the middle Chile. The people itself is nicer, due his lifestyle.
I hope, once my wife finishes her studies in Law, we'll move to south.
