Garganta del Diablo: The Heart of Iguazu Falls
Experience the awe-inspiring force and beauty of the Garganta del Diablo, the most spectacular and iconic cascade in Iguazu National Park.
Garganta del Diablo, or the Devil’s Throat, is the most spectacular and awe-inspiring cascade among the 275 waterfalls that make up Iguazu Falls, straddling the border of Argentina and Brazil. Towering at more than 80 meters in height and shaped like a giant horseshoe, this immense waterfall is the undisputed highlight of Iguazu National Park, drawing travelers from across the globe to witness its thundering power, swirling mists, and kaleidoscopic rainbows.
Why Visit Garganta del Diablo?
- It is the most powerful waterfall in the Iguazu system, channeling the largest volume of water and offering a multi-sensory spectacle of sound and spray.
- Unique geological formation: The horseshoe-shaped chasm is nearly 150 meters wide and plunges 80 meters down, creating formidable clouds of spray that rise above the rainforest canopy.
- Breathtaking viewpoints on walkways and balconies bring visitors to the very edge, maximizing both vistas and the physical sensation of the water’s power.
- Home to rare wildlife: Spot colorful birds, butterflies, coatis, and the specially-adapted great dusky swifts that nest behind the waterfall’s roaring curtain.
What Makes the Garganta del Diablo Special?
Garganta del Diablo is not just a waterfall – it’s the dramatic finale of the Iguazu River as it tumbles over the edge of the Paraná Plateau. The plunging water forms thunderous sheets, while the constant play of sun and mist creates vivid rainbows. Its immense power often leaves visitors speechless and is universally regarded as the most dramatic segment of the broader Iguazu Falls complex.

How to Experience Garganta del Diablo
Garganta del Diablo can be admired up-close on the Argentine side of Iguazu National Park, where the visitor experience is carefully choreographed for maximum impact. Here’s what to expect:
The Journey In: Eco-Friendly Train and Jungle Pathways
- Begin at the Central Station, catching the Tren Ecológico de la Selva (Ecological Jungle Train), a gas-powered, open-air train that glides through lush rainforest teeming with butterflies and exotic birds.
- Disembark at the Garganta del Diablo station and cross a series of elevated walkways (over 2 km round-trip) suspended above the broad, gentle upper Iguazu River. This accessible trail delivers sensory immersion in the surrounding subtropical forest.
As you approach, the sound of plunging water grows ever louder. The anticipation builds, culminating in a first, jaw-dropping view of the falls as you step onto the balcony suspended above the abyss.
The Viewing Balcony and What You’ll See
- The metal observation platform juts out directly above the precipice, so you’re surrounded by cascading torrents and enveloped in shimmering mist. Be prepared to get wet – and to have your breath taken away by the sheer force of nature.
- Witness dense clouds of vapor that can rise over 7 kilometers high on sunny days, sometimes forming multiple rainbows.
- Look down to the bottomless pit, watch for colorful butterflies, and spot swifts darting through the spray to their hidden nests on the cliff walls.
Duration and Accessibility
- The full walkway journey (train plus walking) typically takes about 1.5 to 2 hours round trip.
- The path is fully accessible for strollers and wheelchairs, with railings and resting points along the way.
Other Ways to Get Close
- Boat Tours: Adventurous visitors can book a speedboat ride below the falls for a close-up, splash-filled view of the cascade. Helmets and waterproof bags are provided, as you WILL get drenched.
- Helicopter Tours: From the Brazilian side, scenic flights offer a spectacular bird’s-eye view over the entire Iguazu complex and the swirling chasm of Garganta del Diablo.
When and How to Visit
Best Time of Year
- Year-round access: The falls are an all-season destination, with peak water flow often observed between December and March (summer). However, June to August (winter) brings more stable, comfortable temperatures.
- Heavy rains (especially in spring) may occasionally raise river levels enough to close the walkways for safety. Always check park alerts before arrival.
Park Hours and Entrance
- Iguazu National Park is open every day, usually from 8:00 am until 6:00 pm (last entry late afternoon).
- Separate entry fees apply for the Argentine and Brazilian sides; bring passports if crossing the border.
Getting There
- From Puerto Iguazú (Argentina): Take a public bus, taxi, or join a tour to the park entrance. Convenient parking is available for those driving.
- From Foz do Iguaçu (Brazil): Buses, taxis, or tour operators connect the city with both park entrances. Border crossings require passports and may occasionally involve short delays.
Wildlife and Nature Around Garganta del Diablo
Iguazu National Park is renowned for its biodiversity. The humid subtropical forest provides habitat for over 2,000 plant species, more than 400 types of birds, and countless insects and mammals.
- Birds to watch for: Toucans, jays, swifts, vultures, cormorants, and screamers.
- Mammals: Coatis (unruly but charming), agoutis, otters, bats, and armadillos.
- Reptiles & Amphibians: Various species of turtles and colorful lizards.

Essential Visitor Tips

- Wear quick-dry clothing and bring a waterproof cover for your camera or phone.
- Don’t feed the wildlife, especially coatis, which can be persistent in search of food.
- Plan your route: The Devil’s Throat Circuit is distinct from the Upper and Lower Circuits exploring other parts of Iguazu Falls.
- On sunny days, bring sunscreen and a hat; for the mist and spray, a light rain jacket is recommended.

The entire Iguazu system is a UNESCO World Heritage Site, recognized for its unique beauty and incredible biodiversity. Conservation efforts by both Argentina and Brazil ensure that the region remains pristine, with strict controls on access, wildlife protection, and sustainable tourism.
