Iguazu can be seen from Argentina and Brazil, do both! These immense "cataratas" are mind-blowingly amazing, with a variety of flora and fauna in this tropical jungle region. These really are a must-do in Argentina. Iguazu borders Argentina, Brazil and Paraguay. The Argentinian side of Iguazu boasts 80% of the incredible waterfalls, yet Brazil owns most of the national park of Iguazu. The actual border between the 3 countries runs along the "devils throat" canyon and the Paraná river. The Devil's throat falls, are found within Argentinian territory. The falls were notes as a Unesco world heritage site on the Argentinian side, in 1986. At the end of the day, the Iguazu waterfalls are absolutely majestic and we believe that they should be seen from both sides of the border.
