Guide to Iguazú Falls
Iguazú Falls, Argentina, are the largest waterfall system in the world. Stretching almost 3km along the border of Argentina and Brazil, the falls are made up of roughly 275 different vertical drops, with heights varying from 60 meters - 82 meters. This makes the Iguazú Falls taller than Niagara Falls and twice as wide.
Approximately half of the river’s total flow channels through a narrow chasm called the Devil's Throat which is made up of 14 powerful waterfalls, which can be seen from the Argentinian side of the falls. This creates the widest curtain of water at Iguazú and tends to get photographed the most.
Swoop says
Iguazú Falls is all about pure, glorious sensation – being deafened by the roar of the water and being drenched by the clouds of spray.

Iguazú Falls walkways & trails
There are two trails called the Upper Circuit and Lower Circuit which both offer great views of Iguazú Falls. It is also possible to take a boat onto the river and see the Devil's Throat up close.
On the Argentinian side, you can walk along several boardwalks near to the falls however be prepared to get wet from the spray and mist (take waterproof protection for your camera). Try and visit the falls early in the morning before the crowds arrive and take n case you get caught in the spray.
On the Brazilian side, there’s access to an incredible lookout with an expansive view of the entire falls. You may need a visa to cross the border but the panoramic views are worth the hassle. If you want the ultimate Iguazú experience, it is possible to arrange helicopter trips over the water from the Brazilian side as well.

How to visit Iguazú Falls
The falls can be reached from the the two main towns either side of the falls; Puerto Iguazú in Argentina and Foz do Iguaçu in Brazil. As well as various buses that travel between the falls and the nearby towns, there is also the Rainforest Ecological Train on the Argentinian side. This travels from the Visitors Centre to the Devil’s Gorge station through 7km of rainforest track.
Swoop says
Since 2025, Brazilian authorities require all tourists from the USA, Canada and the UK to have a visa to enter Brazil, even for just a few hours. Please ensure you've checked this requirement before arranging your trip, but remember that over 80% of Iguazú Falls sit on the Argentinian side of the border – including the dramatic Devil's Throat Falls.
