ARGENTINA: Iguazú Falls is the largest set of waterfalls in the world. They are amazing- my friends and I even took a speedboat under the falls! Here is more information about them.
I also saw a baby coatí in almost every direction when visiting Las Cataratas de Iguazú/ Iguazú Falls in Argentina. They were running around everywhere. For more information on the coatí, visit THIS LINK.
