People come from all over the world to see what is perhaps Argentina’s star natural attraction: the mighty Iguazú Falls. Made up of some 275 individual waterfalls and cascades, the park in which they’re located has an amazingly comprehensive and well-maintained set of catwalks that allow you get right up close and personal with the vast sprays of water. At the heart of the site is a semicircular waterfall called ‘the Devil’s Throat.’ These falls are 80 meters high and a massive 2,700 meters in diameter, and because of the excellent catwalks, you can stand right over their edge in perfect safety. Iguazú Falls receive about 1 million visitors a year and have been a UNESCO World Heritage site since 1984. Awesome. So where are they? The falls are located in the far north of Argentina, right on Argentina’s border with Brazil. The nearest town to the falls, Puerto Iguazú, is a short flight or a very long bus ride from Buenos Aires. But wait, there’s more. If you have the time, a trip across the border to the Brazilian side of the falls is highly recommended. Why? Well firstly because the falls themselves are so impressive that it’s worth getting a different perspective on them. While you feel the falls better from the Argentine side, where you can literally reach out and touch them, you see the falls better from Brazil, because from there you can see the entire panorama at once. Another reason to cross the border is to visit the fabulous Bird Park, located right across the road from the entrance to the Brazilian side of the falls. For more information, see here. If you decide that you want to go to the Brazilian side of the falls keep in mind though that while it’s only a short and inexpensive shuttle ride from Puerto Iguazú, some people need a visa to enter Brazil, and this includes citizens of the United States and of Australia. Getting a one-day-only Brazilian visa in Puerto Iguazú is fast – they can do it overnight – but it will cost you (check the amount online as it’s subject to change).
