Brazil - Iguaçu National Park

"The park shares with Iguazú National Park in Argentina one of the world’s largest and most impressive waterfalls, extending over some 2,700 m. It is home to many rare and endangered species of flora and fauna, among them the giant otter and the giant anteater. The clouds of spray produced by the waterfall are conducive to the growth of lush vegetation."
