The 18k, 7-8hr round trip hike to Mirador Las Torres is another must do while in Torres del Paine. You can take the 8am bus from Puerto Natales and transfer busses once you arrive to the main entrance for a short 15 minute bus ride to the start of the hike. It's an all day excursion as you arrive back in Puerto Natales around 10pm, so make sure to bring enough food! #hiking #torresdelpaine #patagonia
