Devil’s Throat, located within Iguazu Falls on the border of Argentina and Brazil, is the largest and most dramatic waterfall in the system. Visitors can reach it via a scenic train ride and walkway that leads to a viewing platform directly above the U‑shaped chasm, where immense volumes of water plunge with thunderous force. Notably, Devil’s Throat measures about 150 metres wide and 82 metres high, producing constant mist and roar, and is considered the highlight of Iguazu Falls, surrounded by lush rainforest and rich biodiversity.
