Torrs Del Paine national park - the "towers of pain..."
Most people seem to hike here for about 5 days but I did at least manage to spend one night in the park. I had a tough 7 hours of hiking up to the towers and back to one of the refugios (small huts/hostles that you can sleep in). It was all pretty tiring but I enjoyed it a lot and the view of the towers from the look-out point was amazing. I was lucky with the weather because last night adn today there was rain and gusting wind - got a tad wet on the way back down this morning!
This was just a quick nip into Chile as I head back to Argentina tomorrow morning. I get to return in about a week though.
