Editor's note: Shared between Brazil and Argentina, it’s worth visiting the park from both sides if you have time: the Brazilian side offers incredible views while the Argentinian side puts you right in the thick of this fantastic park. With lush vegetation and the most powerful waterfalls in the world, this jewel of a park should be added to your bucket list, if it’s not there already. In the meantime, enjoy some spectacular Iguazu National Park wallpapers!
