Another example of price gouging for tourists - $120 pesos for Argentine nationals and $210 pesos for everyone else, and if you do not book ahead with a credit card via one of the any agencies in Esquel or the surrounding tourist towns - forget it. The train station itself is open 2 hours before the train leaves at 1000 am, but bizarrely, the ticket office is only open at the same time as the terrible museum - 0900 am. So you only have one hour to get tickets for the same day. The staff are unhelpful and rude, and the train itself did not look that amazing - the novelty wears off once you look at it. You must time the visit to coincide with good weather because the scenery is not that amazing if cloudy. It is better to look out of the window on your way to or from Esquel as the mountains are just as beautiful there without the train. Not as romantic as you would believe...if trains are your thing, by all means do it, but US$70 is just not worth it.
