Sometimes described as being one of the 7 natural Wonders of the World; in fact, Iguassu Falls are neither the widest waterfall in the world, nor are they the tallest. However, what it lacks in width and height it makes up for elsewhere. On the Parana River, the falls act as a natural border to the countries of Brazil, Argentina and Paraguay and compose of 275 cataracts in total. Best time of year to see the Iguacu Falls is between October and December and as this is such a magnificent sight, it is highly recommended that you make arrangements to stay at least one night here before moving on to your next destination!
