The falls are really spectaculare. It was water everywhere! And lots, lots of water.
From the Brazilian side you have a very good view over the falls and via the bridges and platforms you come very close the falling water.
On the Argentinian side you are more in the falls. Either on pathes and small bridges or in the river in a RIB boat.
The whole place was really an experiance. Especially the RIB ride. But be prepared, it´s WET!!!!
