Introduction: Information on the Iguazu Falls

The Iguazu Falls (Spanish: Cataratas del Iguazú, Portuguese: Cataratas do Iguaçu) is made of some 275 individual waterfalls that stretch out for 2.7km along the border between Brazil and Argentina. The name comes from the word Iguazú, meaning ‘great waters’ in Guaraní, the language of the indigenous Guaraní people. The Iguazu Falls are taller than Niagara Falls in the United States and wider than Victoria Falls in Zambia. Approximately 1.7 million tourists visited the Iguazu Falls in 2018, coming from 166 countries – with ⅔ coming from Brazil and Argentina.

In 1897, Brazilian army officer Edmundo de Barros had a vision for the national parks at the Iguazu Falls. Now, large national parks surround the area on both sides. The Argentinian Iguazú National Park is made of 261 square miles (675 square km), was formed in 1934, and declared a UNESCO World Heritage site in 1984. The Brazilian Iguaçu National Park is made of 660 square miles (1.710 square km), was formed in 1939, and declared a UNESCO World Heritage site in 1986. The national parks work on environmental conservation and preserving natural ecosystems.

The Iguazu Falls rest on the Iguazu River, which is an important tributary to the Paraná River – the second largest river in the world after the Amazon River. The Iguazu River begins in the Serra do Mar coast mountain range, approximately 3,000 feet (900 metres) above sea level, which is located in Southeast Brazil. The drainage basin of the Iguazu River is approximately 30,000 square miles (80,000km2). Approximately 39,000 gallons (148,000 litres) of Iguazu River water flows through the Iguazu Falls every second. It is reported that during months of heavy rain, the water flow can be as great as 3.4 million gallons a second (1.28 million litres) – the equivalent of five Olympic swimming pools a second.

The largest waterfall system of the Iguazu Falls is the Devil’s Throat (Spanish: Garganta del Diablo, Portuguese: Garganta do Diabo), otherwise known as the Devil’s Cauldron or sometimes Union Falls, which is located on the Argentinian side of the Iguazu Falls. Almost half of the river’s water flows through the Devil’s Throat, reportedly reaching heights of 1 million litres every second. The Devil’s Throat drops 260 feet (80 metres) – making it also the longest drop of the waterfall complex. There is a constant bubbling mist that rises from the Devil’s Throat that can rise some 500 feet (150 metres) into the air.

In 2011, after over 100 million votes from voters from 220 countries, the Iguazu Falls were declared one of the 7 New Natural Wonders by the New7Wonders association, along with, Ha Long Bay in Vietnam, Jeju Island in Korea, Puerto Princesa Underground River in the Philippines, Table Mountain in South Africa, Komodo Island in Indonesia, and Amazon Rainforest and River.

Nature & wildlife of the Iguazu Falls and wider Atlantic Forest

The Atlantic Forest, that the Iguazu National Parks are a part of, is now only approximately 7% of its original size. Due to agriculture and logging activities, the area once 460,000 square miles  (1,200,000 km2) – a greater size than the countries of Spain and France combined – is now approximately 40,000 square miles (105,000 km2) – roughly the size of Iceland. 

São Paulo and Rio de Janeiro, Brazil’s two largest cities, were built on what was the Atlantic Forest. The rainforest delta area surrounding the Iguazu Falls is home to 20,000+ species of plant, 900+ species of bird, and 30+ species of butterfly.

Some residents of the Iguazu National Parks:

  • The Jaguar population in the Iguazu National Parks has been slowly climbing thanks to conservation efforts. The latest data from 2019 estimate there are between 85-125 jaguars in the area. Despite these efforts, they are still considered an endangered species at risk of extinction. Around 90% of jaguar have spots similar to that of a leopard and the other 10% are black.

  • The black-horned capuchin [Sapajus nigritus] are one of the most common species of monkey in the area. They are a social animal, typically living in groups of between 6-20 members. They can quite easily been seen when visiting the area.

  • Coati, also known as coatimundis, is a species from the Procyonidae family, related to raccoons. They are very common throughout the Iguazu National Parks and it is recommended that you keep your distance.

Parque das Aves

Parque das Aves, located close to the entrance of the Brazilian side of the Iguazu falls, is a private zoo that homes threatened bird species of the Atlantic Rainforest. They house approximately 1,400 birds of 150 species, as well as a small butterfly house and some reptiles. They report 54% of the birds housed at Parque das Aves have arrived due to animal mistreatment and animal trafficking. The highlight of the visit are the four immersion aviaries, where you can be very close to the birds.

La Lorenza Iguazu

“La Lorenza is our little place in the world and we want to share it with those who are willing to discover a different Iguazú, the one that exists beyond the Waterfall…”

The aim of La Lorenza is to conserve and protect the area from deforestation. In 2018, they opened up to some special tourist excursions. These experiences include walking tours in the forest, kayak expeditions on the Paraná River, and authentic ‘mate’ infusion tasting.

In 2014, Emilio White and Picu Cabrera Castilla bought the lands of La Lorenza Iguazu. The site is located in the Atlantic Forest on the Paraná River, approximately a 45-minute drive from the town of Puerto Iguazú, nestled amongst a farm area where local families live from the land.

Emilio is a wildlife photographer, an ornithological guide, and an Atlantic Rainforest worshipper. He is the author of 3 books – with the latest one about the Iguazú National Park. See Emilio’s incredible wildlife photography over on Instagram @white.emilio. Picu holds a graduate degree in psychology, is also a HR and sustainability consultant, and is mesmerised by nature – namely mushrooms, moss, seeds, and bird nests.

They invite you to visit them and their special natural reserve upon your visit to the Iguazu Falls! See more from La Lorenza Iguazu at and on Instagram at @lalorenzaiguazu.

History of the Iguazu Falls and surrounding area

Around 135 million years ago a volcanic eruption covered the area which was previously desert. The numerous stages of the lava created an inter-layering of basalt and sandstone. Since then, the region has been subject to various shifting of tectonic plates and earthquakes. The waterfalls themselves were formed approximately 20,000 years ago when the Iguazu River began to flow through these breaks in the bedrock.

Humans first settled in the Amazon basin around 9,000 B.C., some of these descendants migrated south, and by 8,000 B.C. the area surrounding the Iguazu Falls was inhabited by Eldorandense hunter-gathers. By 500 A.D., tribes with a semi-nomadic culture began occupying the Iguazu area. Among these tribes were the Guarani people, who still inhabit the surrounding area as well as much of Paraguay, and parts of Argentina, Brazil, Uruguay. Today, Guarani is spoken more commonly than Spanish in Paraguay – with both being official languages of the country.

The Iguazu Falls were little known internationally until the Spanish Conquistador, Alvar Núñez Cabeza de Vaca, explored the area in 1541. Coming across the falls during an expedition to what is modern day Asunción, Paraguay, calling them “Saltos del Santa Mary” (the jump or leap of Mary, mother of Jesus).

After the Jesuits who had moved to southern Paraguay, Brazil, and the province of Misiones were then expelled by the Crown of Spain in 1768, the area would be largely deserted. Later in the 18th century, Gregorio Lezama, an Argentine businessman and politician, would sell the land, it being listed at auction as “a block of jungle that borders several waterfalls”. In 1907, the lands were acquired by Domingo Ayarragaray, who had a vision for the touristic potential of the Iguazu area, who set up the first local hotel.

Legends of the Iguazu Falls

The story of Naipí and Tarobá

Local legend instead attributes the creation of the Iguazu Falls to aborigine girl, Naipí. This tale centers around the blood-thirsty god, M’Boi, who has the head of a parrot and the body of a snake. Each year M’Boi would call upon the Guaraní tribe for a beautiful maiden, and the tribespeople granted his requests to appease his anger.

This annual meeting would bring together Guaraní tribes from far and wide. One year, young chieftain Tarobá met the beautiful Naipí, who had been chosen to be sacrificed to M’Boi. Enchanted by Naipí he pleaded with the other chiefs that she be spared, to no avail.

The evening before the ceremony Tarobá kidnapped Naipí and they escaped on a canoe that had been hand-carved by Tarobá. Sadly, M’Boi watched this escape unravel, and with a fury began beating the riverbed with such force that he created the Garganta del Diablo, or Devil’s Throat.

The lovers were separated, with Tarobá falling to the riverbank and Naipí on course to cascade over the Devil’s Throat. Before she fell M’Boi turned Naipí into a waterfall and Tarobá into a tree at the side of the river. This act of revenge was to keep the couple apart for eternity.

M’Boi is said to lurk in the waters at the foot of the Devil’s Throat to this day.

The shaman and the rainbow

Another local story accounts for the everpresent rainbow that surrounds the falls. A local shaman received a message from his god informing him that he would “show the world a marvellous thing”.

The other townspeople didn’t take any notice of the shaman and his message. Then one night, under a full moon, there was a random flash of lighting, and there, sitting in front of the Iguazu Falls was a rainbow.

Do you need a Brazilian and Argentinian visa to visit the Iguazu Falls?

From Ron Sassen’s ‘A Comprehensive Guide to Iguazu Falls’ – read on Kindle/Amazon.

Answered by Carlos Daniel Tinca of RipioTurismo:

How many days do you need to visit Iguazu Falls?

“The suggested time is 2 night / 3 days, which gives you enough time to visit both sides of the falls. The only condition on this itinerary is that you have to arrive in the morning or depart in the afternoon, based on that you will visit the Brazilian side on your arrival or departure date.

Anyway, Iguazu Falls is a very flexible destination, you can even visit it in a single day, arriving in the morning and departing in the last flight.”

Here are some helpful links:

When is the best time to go to Iguazu Falls?

“I would say April to May and September to October, because in those date in low season (few people around) and the climate is very nice.”

Check this page for more details:

Do you need a tour for Iguazu Falls?

“As a travel agent… you don’t need a tour to visit the falls :P.

The truth is that visiting the falls can be done without guide and you will enjoy it without problem. But I suggest at least do one side of the falls with a guide, because the guide can provide very nice information about the place and learn a lot of the destination. The small group tours aren’t expensive and they cover the the three main circuits of the falls.

I suggest using the guide on the Argentinian side, as this side is bigger. The Brazilian side can be visited without a guide without a problem, as this park is smaller and easier to visit.”

Why should I visit the Iguazu Falls?

“I went there three times, and usually, at the office we go there every 3-4 years. And every time we enjoy it a lot. It’s a unique destination and each time you go you enjoy it like the first time. Besides the falls, there are very interesting places to visit around besides the falls, like The Argentine Experience or  La Lorenza Iguazu.

It is one of the main attractions of Argentina, and it can be easily visited. I think it’s a must.”
