So far our experience of bus travel in Argentina has been good and so much more comfortable than Peru or Bolivia. Yesterday we completed a series of trips lasting 29 hours, our longest trip yet: Cafayate to Salta, Salta to Resistencia, and Resistencia to Puerto Iguazu. We are now right up in the north-east corner of Argentina, on the border with Brazil, and the location of the Iguazu Falls. We have dropped in altitude some more and now definitely back in a rain forest area. Our plan is to take another couple of days break before heading south towards Buenos Aires.
