Iguazu Falls on the border of Brazil and Argentina is one of the seven wonders of the natural world. There can be more than 265 different falls in the 1.7 mile long panorama of falling water. I tour the falls with Brazilian guide Carlos Barros and take a zodiac under the falls for my show National Geographic Weekend. It's a sight that should be on everyone's must visit list.
