With its jungle setting, the Iguazu Falls are perhaps the world's most beautiful waterfalls. The Iguacu River hurtles over high cliffs into a marvellous curved amphitheatre several miles wide. The noise is tremendous and huge clouds of mist float up as the cataract water falls over 60 metres into a gorge. From the Argentinian side, there's a of series of catwalks to get close up views of the Devil's Throat where about half of the river's water falls into the long and narrow chasm. In Foz do Iguaçu is the Parque das Aves with well displayed birds as well as reptiles & butterflies.
