Recently I have discovered a masterpiece in Santiago for trekking, the Parque Natural Aguas de Ramon. I was surprised as my Chilean colleagues didn't know it before.
The park has three routes. 1. a very basic one which covers around 1km; 2. a second one with almost 7km; 3. and the most difficult one with 17,2km.
I'm looking for partners to do the third route. If anyone is interested to join, show your enthusiasm on this topic and then we coordinate a group! I have done the second route and I can tell: it's amazing!
