Nariz del Diablo (Nose of the Devil) is heavily promoted to tourists, so almost everyone ends up doing it. You sit on top of a crusty old train and go down the side of a valley. It’s pointless, the views are lame and you’re crammed in like sardines with other under whelmed tourists. Everyone was a bit grumpy because some dickhead Russians were getting pissed on the roof and were annoying everyone.
