Dividing the upper and lower Iguazu River is the Iguazu Falls. The parks that contain the falls on both the Argentinian and Brazilian side of the border are UNESCO World Heritage sites. Because of the width and shape of the falls, Iguazu Falls offers better views than other falls like Niagara or Victoria. At one point you can be surrounded by 260 degrees of waterfalls. The Brazilian side of the falls has a walkway that extends towards the falls.
To get to the Park on the Brazilian side you can take a taxi or bus from the Foz do Iguaçu International Airport. On the Argentinian side you can take a taxi or bus from the Cataratas del Iguazú International Airport to Iguazu National Park to view the falls from the Argentinian side.
