The W trek is the most famous trek in Patagonia. If you are interested in doing the whole trek and seeing the most amazing views but you don’t have much time, this is how to do it in 3 days. However, I must warn you - it is exhausting, difficult to plan and quite risky! In this post, I will describe the first day of the trek - getting to the Torres del Paine National Park, stopping at Paine Grande Camping, trekking to the Glacier Grey and back to Paine Grande Camping site for the night.
