Iguazu Falls is traditionally described as having 275 principal cascades.
The falls lie on the Iguazu River along the border between Argentina and Brazil. Their individual drops and channels are spread across a broad horseshoe-shaped system, rather than forming one single waterfall. The number 275 is a widely cited count, though the visible arrangement can change with water levels and the way channels are classified.
The largest and most dramatic section is the Devil’s Throat, or Garganta del Diablo, where the river pours into a deep, U-shaped gorge. Argentina’s Iguazú National Park and Brazil’s Iguaçu National Park protect the surrounding rainforest and viewpoints.
Iguazu is often compared with Niagara Falls because both are major border waterfalls, but Iguazu is wider and consists of many more separate cascades. The falls were designated a UNESCO World Heritage Site in 1984 on the Argentine side and in 1986 on the Brazilian side.
