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.

The Devil’s Throat in Iguazu Falls: General Information
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.

Where Is the Devil’s Throat and How Do You Access the Trail?
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.

The Ecological Jungle Train in Iguazu Falls
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.
