Admire the grandeur of the Iguaçu Falls as you look at them from the Brazilian side. The falls are horseshoe-shaped, and from here you have a panoramic view of two thirds of the waterfalls, which are on Argentine soil.
Walk the jungle trails in the jungle, then come out on the circuits. Admire the contrast between the lush green and the foaming white. Feel the might of that mass of water that plunges ceaselessly over the cliffs.
Tell your guide your abilities and preferences, for there are many options and trails to explore.
