I love visiting Punta Arenas because it is a really nice city. It is a small city, the streets and the air are so clean, the weather is so cold the entire year so you can go away from the high temperatures of Santiago in summer, and you can enjoy the snow in winter (and the winter parade). The architecture of Punta Arenas is so beautiful . You can enjoy a lot of beautiful places near from Punta Arenas too, as Puerto Natales, Torres del Paine, Ushuaia (in Argentina), etc.
