I stayed in Puerto Natales for a couple of days. I really liked the small town and its atmosphere. The following pictures give some impressions of the town at the end of the world.
My advice: Take a taxi to Mirador Dorotea. It is a viewpoint on top of a hill outside of Puerto Natales. The taxi will take you to a small sheep farm where the hike up the hill starts. After about one hour you have an amazing view of Puerto Natales and the sea. If you are lucky you will be invited into the farmhouse on your way down for some tea and biscuits 🙂
