Until you’ve visited Iguassu Falls / Iguaçu Falls at the border of Argentina and Brazil, you can’t say you’ve seen the best waterfalls in the world.
A fantastic variety of hiking trails and paths take you up close to many of the hundreds of different waterfalls that are found here.
The largest “cataract” here is that of Union Falls, pictured here. Viewed from the Argentina side of the waterfalls, the roaring thunder of the power of the water was intense and the mist gave everyone a nice cooling down in the otherwise scorching hot sun. One of the most impressive waterfalls I saw at Iguassu.
