The Iguazú Falls, a truly awesome natural wonder along the border of Brazil and Argentina. It’s well worth viewing from both sides, on the Brazilian side you get up close and personal with the cascading water (take the speed boat trip under the falls it’s stunning and you will get soaked!). The Argentinian side reveals incredible panoramic views of the 275 individual falls – it is one of the widest waterfalls in the world. Can you spot the rainbow?! They constantly shimmer in and out of view….
