Iguazu Falls is an extraordinary natural destination located on the border between Argentina and Brazil. The falls were chosen as one of the New 7 Wonders of Nature, while the national parks that protect them on both sides of the border are recognized as UNESCO World Heritage Sites.
Former U.S. First Lady Eleanor Roosevelt is often associated with the famous phrase, “My poor Niagara…” after seeing Iguazu Falls. Whether or not the anecdote can be fully documented, it reflects the impression created by the scale and power of this remarkable natural setting. The entire route through the falls on the Argentine side offers memorable views, but its most iconic attraction is the renowned Garganta del Diablo, known in English as the Devil’s Throat.

2 Day Trip to Iguazu Falls From Buenos Aires
The Devil’s Throat is the most powerful and recognizable section of Iguazu Falls. Here, several waterfalls converge into a large horseshoe-shaped gorge on the border between Argentina and Brazil, with a drop of around 80 meters. The enormous volume of water creates an impressive combination of sound, spray, and mist that can be experienced from very close range.
This section of the falls concentrates a significant portion of the Iguazu River’s flow and is one of the most visited viewpoints in the national park. Its scale is especially striking because visitors approach it from above, crossing the upper Iguazu River before reaching the final viewing platform.
To reach the Devil’s Throat from the Argentine side, visitors take the Ecological Jungle Train to Garganta Station. From there, a steel walkway extends approximately 1,100 meters across the upper Iguazu River until reaching the Devil’s Throat viewpoint.
The route itself is part of the experience. The walkway crosses quieter sections of the river surrounded by vegetation before gradually approaching the sound and mist of the falls. The same walkway is used on the return journey, making the complete walk approximately 2,200 meters round trip. The walkway has no stairs and is designed to be accessible to visitors with reduced mobility.
The Devil’s Throat is located along the border between Argentina and Brazil, but the walkway that reaches the famous upper viewpoint is accessed through the Argentine side of Iguazu National Park.
After entering the park, visitors can use the Ecological Jungle Train to reach Garganta Station. From there, the walkway crosses the upper Iguazu River and leads directly to the viewing platform overlooking the Devil’s Throat. At the end of the trail, visitors can experience the immense volume of water plunging into the gorge from close range.
This is one of the park’s most popular circuits and an essential part of the Argentine-side visit.

There are also other ways to experience Iguazu Falls from different perspectives. Boat tours departing from the lower river area bring visitors close to several waterfalls, while helicopter flights from the Brazilian side provide panoramic aerial views of the entire waterfall system.
The Ecological Jungle Train is the transportation system that connects visitors with the main circuits of Iguazu National Park on the Argentine side. The narrow-gauge train travels through the subtropical forest, making it easier to move between the principal areas of the park while also offering views of the surrounding vegetation.
The train departs from Central Station and connects with Cataratas Station and Garganta Station. Cataratas Station provides access to the main waterfall circuits, while Garganta Station is the starting point for the walkway leading to the Devil’s Throat.
The locomotives are electric or powered by LPG, helping to reduce their environmental impact as they travel through the protected forest. The open carriages also allow visitors to experience the vegetation, sounds, and atmosphere of the surrounding jungle during the journey.

Devil’s Throat, also known as “Garganta del Diablo,” is undoubtedly one of the most awe-inspiring wonders of the magnificent Iguazu Falls. What makes it so special? There are countless reasons that will leave you breathless. From its grandeur and stunning natural surroundings to the mesmerizing ambiance, Devil’s Throat is an experience like no other. So, prepare yourself for an unforgettable encounter with the sheer magnificence of Devil’s Throat at Iguazu Falls.
We all know that Devil’s Throat is an iconic and breathtaking destination, but what exactly is it? Let me paint you a picture. Imagine a colossal U-shaped waterfall nestled within the heart of the Iguazu River, where an immense volume of water crashes down into a narrow chasm. This chasm is encircled by towering cliffs and magnificent rock formations, creating a natural amphitheater-like spectacle. The location alone is awe-inspiring, but there’s so much more to it.
The Devil’s Throat stands as the largest and most formidable waterfall within the Iguazu Falls system. It spans a staggering width of approximately 492 feet (150 meters) and an impressive height of 269 feet (82 meters). Just envision the sight! The sheer magnitude of this natural wonder is truly astounding. But size isn’t the only factor that makes it incredible. The relentless rush of water, the perpetual mist that envelopes the surroundings, and the thunderous roar combine to create an experience that transcends the ordinary.
To reach the Devil’s Throat, visitors typically follow a well-marked walking trail or board a specialized train that leads them to a carefully positioned viewing platform. This platform offers an unrivaled vantage point directly above the chasm, granting visitors a front-row seat to witness the astonishing cascade of water. Standing there, one can’t help but be captivated by the raw power and energy exuded by the falls, immersing oneself in an utterly mesmerizing spectacle.
The Devil’s Throat undoubtedly steals the show when it comes to exploring the wonders of the Iguazu Falls. Its immense size, dramatic setting, and captivating sensory experience make it the ultimate highlight of any visit. It serves as an undeniable testament to the extraordinary forces of nature, drawing in travelers from all corners of the globe who yearn to witness its awe-inspiring beauty firsthand.
Visitors should allow approximately 90 minutes to 2 hours for the complete experience. This estimate includes waiting for the train, walking to and from the balcony, and spending time at the viewpoint. Actual timing depends on visitor numbers and train operations.
The Iguazu Falls developed along a vast basalt plateau formed by volcanic activity millions of years ago. Over time, the Iguazu River eroded the layered volcanic rock, creating a complex system of drops, islands, channels, and gorges.
Devil’s Throat developed where several river channels converge along the semicircular basalt edge. The continuous force of the water gradually reshaped the rock and caused the falls to retreat upstream.
This geological process is still active. Water volume, erosion, and seasonal changes continue to influence the shape and appearance of the waterfall system.
The deep chasm, the narrow concentration of several channels, and the vast quantities of mist are what give Devil’s Throat its distinctive character. It is not an isolated waterfall, but the most concentrated section of a much larger formation.
Let’s explore a few reasons why Devil’s Throat is truly an astonishing marvel:
On selected nights each month, visitors can experience Devil’s Throat during the Full Moon Tour to Iguazu Falls. The guided evening experience includes access to the park after regular opening hours, transportation on the Tren Ecológico de la Selva, and a nighttime walk along the upper river walkway to the Devil’s Throat balcony. The activity generally operates on five nights around the full moon, with limited capacity and several scheduled departures each evening. The official experience currently lists three departure times and an approximate total duration of two and a half hours. Moonlight, mist, cloud cover, and weather conditions affect visibility, so a moonbow or fully illuminated view cannot be guaranteed. Advance booking is strongly recommended because capacity is limited and dates depend on the lunar calendar and park operations.
Devil’s Throat is surrounded by the Paranaense rainforest, part of the Interior Atlantic Forest. The two neighboring national parks protect an exceptionally diverse ecosystem shaped by dense vegetation, high humidity, rivers, islands, and permanent waterfall spray.
UNESCO records approximately 2,000 plant species and around 400 bird species within Iguazú National Park. The protected area is also home to mammals, reptiles, amphibians, fish, and countless invertebrates.
Visitors commonly encounter:
Larger mammals such as tapirs, ocelots, giant anteaters, and jaguars inhabit the protected forest, although sightings in the public circuit areas are uncommon.
Wild animals should never be touched or fed. Food can change their behavior and increase the risk of bites, scratches, and conflicts with visitors.
The Devil’s Throat circuit is reached through Iguazú National Park on the Argentine side. Most visitors begin at Estación Central and use the Tren Ecológico de la Selva to travel through the park.
The usual route is:
The walkway measures approximately 1,100 meters in each direction, making the complete circuit about 2,200 meters round trip. It is flat, has a low level of difficulty, and is fully accessible for wheelchair users.
Train capacity and departure intervals can vary according to visitor numbers and park operations. Visitors may need to obtain an assigned departure time at the ticket office, so it is advisable to organize the Devil’s Throat visit soon after entering the park. The official park map specifically instructs visitors to collect their free train turn at the ticket office. An alternative pedestrian route connects Estación Cataratas with Estación Garganta, but it adds a considerable walk and may not be available under all conditions. Most visitors use the train for at least one section of the journey.
The final balcony is positioned directly above the main chasm. Visibility changes constantly as the wind moves large clouds of mist across the viewing area.
Visitors should expect:
A lightweight rain jacket or poncho is useful, although it may not keep you completely dry near the edge. Phones, cameras, documents, and other water-sensitive belongings should be protected before reaching the final section.
The experience can look very different depending on the river level. At higher flow, the water and mist may dominate the entire view. At lower flow, more of the rock walls and individual channels may be visible.

The name Devil’s Throat refers to the deep, narrow chasm into which several channels of the Iguazu River converge. From the viewpoint, the water appears to disappear into a vast opening surrounded by mist. The throat-like shape of the formation, combined with the intense roar of the water, likely contributed to the dramatic name. In Spanish, the site is called Garganta del Diablo. In Portuguese, it is known as Garganta do Diabo. The exact historical origin of the name is not clearly documented. It is best understood as a descriptive name inspired by the shape, sound, and force of the waterfall rather than as a precise historical or geological term.
If you’re planning to visit the Iguazu National Park and experience the awe-inspiring Devil’s Throat, there are several important points to consider before your trip. Here are some key factors to keep in mind:
Devil’s Throat can be visited throughout the year. Iguazu has a humid subtropical climate, so rain is possible in any month and river levels can change quickly. For fewer crowds, arrive early in the morning. Summer is hot and humid, while autumn and winter generally offer milder temperatures for walking. Higher water levels can make the falls more powerful, but they may also increase the mist and reduce visibility. Extreme river conditions can occasionally cause temporary closures.

In addition to the breathtaking Devil’s Throat, the Iguazu Falls area offers a multitude of other captivating attractions for you to explore. Let’s delve into some of these remarkable highlights:
There’s no doubt that the Devil’s Throat is the most powerful and recognizable section of Iguazu Falls and an essential part of any visit to the Argentine side.
The circuit combines a journey through the rainforest, a flat walkway across the upper Iguazu River, and a viewing platform directly above the main chasm. It is accessible, relatively easy to walk, and unlike any of the more distant panoramic viewpoints found elsewhere in the park.
Visitors should arrive early, protect their belongings from the spray, allow enough time for the train and walkway, and verify the circuit’s status before traveling.
For the most complete experience, combine Devil’s Throat with the Upper Circuit, the Lower Circuit, and an optional boat activity. Together, these experiences show the scale, diversity, and extraordinary natural setting that make Iguazu Falls one of the world’s most remarkable waterfall destinations.
