You arrive along the triple-border corridor with the river pushing at three nations’ edges — Brazil, Paraguay and Argentina — and the day opens like a map of contrasts: rushing falls, a humming power plant and busy cross-border commerce. The first scene is Salto Monday, where the waterfall throws itself off basalt steps and the spray dares you to step closer; nearby paths thread through remnant Atlantic Forest that birds punctuate with sharp calls.
