Vast torrents of water thunder over the various cascades, making for a truly awe-inspiring sight. The falls are divided between Brazil and Argentina.
While the Brazilian side is arguably the most spectacular, with a much more panoramic view of the immense cascade, the Argentine side is more suitable for exploring. To really experience the falls however, one must visit both sides and a stop at the Argentine Interpretive Center can provide much useful information about the falls and surrounding flora and fauna.
Try to pick up at least a few basic greetings, directional questions, and common curiosities in the native language(s) before you leave for your trip.
