Our group had the unique opportunity to spend three days in the Iguazú Falls, undoubtedly one of the most imposing natural attractions in all of South America. Iguazú is a sub-tropical rainforest spread across southern Brazil, eastern Paraguay and the northeast of Argentina. The ecosystem here is truly unique: the subtropical weather, the abundant rain, and the type of soil result in an ecosystem of giant trees, tiny insects, and animals of all shapes and sizes.

The Iguazú Falls are the most impressive natural attraction of the park. The falls are formed by two rivers, the Iguazú and the Paraná River. The Iguazú River is a natural boundary between Brazil and Argentina. It snakes through smooth geography on a plateau before hitting a series of faults and dropping up to 80 meters, and the waterfalls divide the river into Upper and Lower Iguazú . The Iguazú River later drains into the Paraná River. The biggest waterfall in the park, called the Devil’s Throat, is formed where the Iguazú River forms a tributary and cascades into the Paraná River. It’s pretty darn cool.
We spent a total of three days in the park, and we had a wonderful guide named Alejandro who accompanied us during our entire stay in Iguazú. We arrived in the afternoon on Tuesday, and our first activity was a night excursion through the park. In addition to seeing giant months and an array of insects of all shapes and sizes, the highlight of the walk was a large lagoon. Thousands of frogs and toads live in the lagoon and they were singing an orchestra of different sounds for us to enjoy. At the lagoon, we turned off the lights and had two minutes of silence. The sounds coming from the frogs and toads were INTENSE. This was a cool walk, and we knew we were in for an amazing few days.
The falls are incredible. In the local Guarani language, the term “Iguazú” means “great waters” and this is exactly what we experienced. There are more than 270 falls in the park, the most famous being the falls created by the Devil’s Throat canyon. The water produces a thundering sound and we got soaked from the mist. We walked along the
upper circuit as well as the lower circut. On our second day, we followed a small waterfall that emptied into a pool. It was perfect for an afternoon dip!

- We took a lunch break at this natural pool. A lot of people actually went swimming here, and we showered under the falls!
The highlight of the park was a boat ride that literally brought us right under the falls. We were prepared to get soaked! It’s amazing to see the falls from a distance, but it’s a completely different experience to go right up to them. We spent two whole days in the
park, walking along different trails and learning about different plants and animals. Some of the animals were really friendly and walked right next to us!

We're getting soaked! We went right up to the waterfalls in a boat. Good thing for rainjackets and a change of dry clothes

We did many other fun things in Iguazú, too. We learned a lot about yerba mate, the ubiquitous herb used for tea that all Argentines drink. Yerba mate grows naturally in the Iguazú forest and we took advantage to buy a lot of natural tea produced in the region. We also went to a cool area called “The Three Borders”. At the confluence of where the Iguazú and Paraná rivers meet, the borders of Paraguay, Brazil, and Argentina fall on a single point. We were in Argentina and looking at both Paraguay and Brazil. Pretty cool!
During these few days, we were truly immersed in nature. A lot of students had no idea what to expect from Iguazú and were blown away by how beautiful this place was. Our next stop will be cosmopolitan Buenos Aires. So long to the jungle!!

This fuzzy animal is called a coati. They are super friendly. We had to be careful that one wouldn't snatch a camera!
