Situated in Iguazú National Park, some 20 km. from Puerto Iguazú in the north of the province of Misiones, Argentina, the Iguazú falls are shared by Brazil and our country.
A legend says that a big snake called "Boi" lived in the river.
To calm its ferocity, aborigines sacrificed a woman every year as an offering.
But once a brave guarani aborigin kidnapped the woman and saved her from the traditional rite escaping through the river.
Boi burst in anger, bent its body and split the river forming the cataracts separating the man and the woman.
