Iguazu Falls are the largest waterfall in the world. The falls are at the border between Argentina and Brazil, however, the majority of the falls (about 80%) are on the Argentina side. We visited them from the Argentina side.
The falls are divided into upper and lower Iguazu. Even though compared to Victoria Falls or Niagara Falls, Iguazu Falls has a very unique structure with roughly 275 distinct falls and many large islands. The longest drop is about 82 meters (269 ft).
