Best: May-Aug · Great: Feb-Apr, Sep, Nov
Four distinct seasons run through the year here, from May's chill to January's warmth, with rain spread fairly evenly across the calendar rather than concentrated in one stretch. In May, expect highs around 23°C with rain on roughly 9 days of the month.
Walk the Argentine side's extensive trail network, including the Devil's Throat catwalk that puts you right at the edge of the largest cascade, then cross to the Brazilian side (Foz do Iguaçu) for the classic panoramic view of the whole falls system. A boat trip beneath the falls themselves is worth the soaking, and the surrounding subtropical rainforest is home to coatis, toucans, and butterflies.
Try Argentine-style asado and chimichurri on the Misiones side, or Brazilian churrasco and feijoada across the border in Foz do Iguaçu.
