Located at the borders of Argentina, Brazil and Paraguay and one of the UNESCO wonders of the Natural World, Iguazu Falls is the largest waterfall in the world. With over 275 falls, fuelled by the water of 30 different rivers, its power is tremendous. Upon seeing Iguazu, first Lady Eleanor Roosevelt reportedly exclaimed "Poor Niagara!"
Vastly larger than North America's Niagara Falls, Iguazu is only rivaled by Southern Africa's Victoria Falls. Whilst Iguazu is wider because it is split into 275 falls - Victoria Falls is the largest single curtain of water in the world. Iguazu and Victoria are generally regarded as the world's most spectacular waterfalls and having seen both I am divided as to which is the more impressive. Of all the many tall cascades that make up Iguazu Falls, the semi-circular Devil's Throat is by far the most awesome. It is the world's mightiest single water fall (in terms of water-flow volume) - and its incessant roar is deafening, to the point of being terrifying. On the Argentine side the paths take you through a 600m stretch of calm water to an awesome viewing platform at the edge of the falls where you get very wet, but it is absolutely worth it. You begin to hear the rush of the water and as you get closer the roar gets louder and the cloud of mist gets larger.
The Argentine side is more panoramic and grandiose while on the Brazilian side you are right in the action, traversing catwalks and walkways that get right next to the rushing, thundering water. From either side expect to get wet from the mist and spray. The falls are best seen in the morning for taking pictures. My best advice: See both sides.
The best time to visit the falls is March, August or September. Summers are hot, intensely so, (December – March) and the heaviest tourist season. This is also the rainy season and some sightseeing trails can be closed due to rain damage. During the dry season (April to July) you will have warm blue sky weather, however Iguazu Falls can dwindle in strength and if you are very unlucky they may be completely dry which occurs for a week or more every few decades.
I also experienced the falls on a thrilling boat ride, which you can read more about here.
Tip – Take a large memory capacity digital camera as there are photo opportunities at every step and a water proof plastic bag to protect it.
