Iguazu National Park

Quick Navigation

Iguazu National Park is located in Argentina along the Iguazu River which creates a natural border between the country and Brazil. The national park encompasses an area of 261 square miles (677 sq km) and is a sister protected area on the Brazilian side known as Iguacu National Park.

The majority of the falls, approximately 80%, occur within Iguazu National Park. The majority of descriptions of the fall indicate there are 275 distinct separate drops, however, some believe there are some that are continuations of a drop and lessen the number to around 85 different drops.

Iguazu Falls stretch across a distance of 1.7 miles (2.7 km) with the highest drop occurring at Devil’s Throat that reaches a height of 269 feet (82 m). The Iguazu drops vary from 197 feet (60 m) to the 269 feet (82 m) drop at the canyon head where it is affectionately known as Devil’s Throat.

The multi-drop and tiered waterfall complex are characterized by a staircase rock formation created by layers of basalt. The staircase sizes vary from 115 to 131 feet (35-40 m) in height. Iguazu Falls have an average flow rate of 62,010 cubic feet per second (1,756 m3/s).

Iguazu National Park and the Iguazu Falls region feature a spectacular family of wildlife that unfortunately often rarely seen. Predator species include the jaguar, jaguarundi, and ocelot. Some intriguing endangered species include the giant otter and the giant anteater.

Toucan can be seen more easily on the Argentine side of Iguazu Falls; however, it takes some effort and patience because sightings are more common during the early morning hours just prior to sunrise. Sightings are still possible, but this timeframe offers the greatest probability.

The coati is similar looking to a raccoon type of creature. The good news is that this is fairly tame and is often experienced along the trails of the lower or upper falls trails. Butterflies are numerous near the location where the train ends on the way to Devil’s Throat.


Iguazu Falls are the highlight attraction of Iguazu National Park. Since the majority of the falls occur on the Argentine side, there are more trails and varied views of the falls. The best way to experience the falls is by taking the various trails that provide postcard views of the falls. 

Iguazu Falls

Iguazu Falls is the largest waterfall system in the world. Depending on the definition of a waterfall, there are either 85 or 275 individual waterfalls that are part of the larger Iguazu Falls system.

Iguazu Falls span 1.7 miles (2.7 km) along and over the border between Argentina and Brazil.  Devil’s Throat that measures 269 feet (82 m) and is the tallest drop across all the falls. The various falls vary in height from 197 feet (60 m) to 269 feet (82 m).  This highest point is locally called Garganta del Diablo, which translates as Devil’s Throat.  The collective span is wider than Victoria Falls located on the border between Zambia and Zimbabwe.

Iguazu Falls have an average flow rate of 62,010 cubic feet per second (1,756 m3/s).  Niagara Falls on the border of Canada and the United States has a higher volume of water, but Iguazu Falls is wider and taller.  Many would claim, that Iguazu Falls is the most beautiful waterfall in the world.


Each month during a 5-day window where there is a full moon, visitors are allowed to purchase a train trip up at night to see Devil’s Throat under the light of the moon. It is possible to see moonbows, which are rainbows created by the mist of the falls and the light of the moon.

Things To Do:

Hiking amongst the falls is the primary activity of the national park, however there are other ways to engage Iguazu Falls and the rainforest that surrounds it.

Speed Boat Falls Tour

Upper Falls Eco-Float Tour

After visiting Devil's Throat, you can opt to take a float trip on the river above the falls.  Your guide will take you in and out of islands allowing you to see different facets of nature along the way.  This is a relaxing trip enjoying the river and forest.

Train to the Top

Take a train ride to the top of the falls where you can see directly into Devil's Throat and the canyon below.  You can also access other activities like a float trip on the river.

Iguazu National Park Trails

You can hike below the falls, on top of the falls, around the rainforest, and out to Devi's Throat which is the highest point of the falls.  Hiking allows you to experience up-close views of the falls as well as other postcard worth views.
