Today I have visited Parque Nacional de Iguazù in Northern Argentinia. Even though sun wasn´t shining until the afternoon, it was still very hot and especially very humid. Like Els wrote in 2004 the park also appeared to me like a theme park - a map with action activities, bus arrivals, restaurants etc. proof me to be right. In a first step I took the inferior circuit, which is the track walking to the bottom of some of the many waterfalls. This was very impressive especially the first view on the Iguazú falls out of the rainforest with the roaring in the back and also standing below one of the waterfalls. The superior track takes you tot he top of many of the falls and is not so spectacular. It shows you the Río Iguazù flowing towards the falls in a quite calm way. Also you see the edge where it all falls down. But from below it´s more spectacular. The Macoco trail was nice to watch animals. The highlight were 4 toucans but I have also seen many spiders, some saurians, many coatis, other birds and butterflies. The highlight of the visit however is the walk to Garganta del Diablo. This is really like a devil´s throat were vast amounts of water fall down. Astonishingly many butterflies also make their way into the throat and came back up again. Humans would surely not survive a jump into this tremendously big and deep pool.
