The Iguazu Layout

Sorry about the creases - I only snapped the shot so I could use it as a reference to figure out where I took my other photos.

The colored lines are the various walking trails - the hatched/dashed/whatever sections are steep uphills and downhills. No scale, but a rough guide: I think it took me maybe twenty minutes to walk from the train stop (Estacion Garganta del Diablo) at the top of the map to the falls themselves via the orange trail. But that is sort of a wild guess.
