Best to arrive early, it gets crowded from 10 am

The Devil's Throat from above. In a word, impressive! Unfortunately, it's very crowded.

The Gargantua del Diablo, or Devil's Throat, is a churning mass of water that plunges down from three sides.

If possible, I recommend taking the boat that brings you closer to the waterfalls.

The most beautiful viewpoint in the park, and of course very busy! In the evening there is a completely different light than in the morning. For this reason alone, two visits (at the beginning and at the end of the tour) can be worthwhile. The water level, which sometimes changes completely within a few hours due to a dam above the falls, also makes a difference. When the water flow is high, you get wet (pleasantly cool), but unfortunately so do your camera lenses. When the water flow is lower, it is much easier to take photos!

The region is dominated by the magnificent Iguaçu Falls and its surrounding national park, which is a UNESCO World Heritage site. Another significant natural monument is the Parque das Aves (Bird Park), dedicated to bird conservation.
The Iguaçu Falls form the largest waterfall system in the world, spanning nearly three kilometers with drops up to 80 meters. The Brazilian side offers expansive panoramic views of the entire system, including the powerful Devil's Throat, where approximately half of the Iguaçu River's water cascades.
Yes, within the Iguaçu National Park on the Brazilian side, the Trilha das Cataratas (Waterfall Trail) is a paved and relatively flat trail, approximately 1.2 to 1.5 kilometers long. It offers multiple viewpoints and culminates in a walkway providing close-up views of the Devil's Throat, making it accessible for most visitors.
The Iguaçu National Park protects a significant portion of the Atlantic Forest, which is rich in biodiversity. Visitors may encounter diverse flora and fauna, including rare and endangered species like the giant otter and giant anteater, as well as howler monkeys, ocelots, jaguars, and caymans.
Parque das Aves is a private institution near the Iguaçu National Park entrance, dedicated to the conservation and recovery of birds, especially those from the Atlantic Forest. It houses over 1,000 birds from approximately 140 to 165 different species, many of which are endangered. Its unique immersion aviaries allow visitors to walk among the birds, offering an interactive and educational experience.
The best time to visit is generally during the dry season, from April to September, when the weather is milder and there is less rainfall. However, the falls are impressive year-round, with higher water volumes during the rainy season (October to March) offering a more powerful spectacle.
Yes, both the Iguaçu Falls and Parque das Aves are highly family-friendly. The Iguazu Falls (Brazilian Side) offers paved trails suitable for all ages, and Parque das Aves provides engaging, interactive experiences with birds that children often love.
For the Iguaçu Falls (Brazilian side), plan at least half a day to fully experience the trails and viewpoints. For Parque das Aves, allow 2-3 hours to explore the aviaries and other sections. Many visitors combine both attractions into a full day due to their close proximity.
Both Iguaçu National Park and Parque das Aves have dedicated parking facilities. The Entrance to Iguazú National Park serves as the primary access point, and public transport options, such as local buses, are also available from Foz do Iguaçu city center to both sites.
Comfortable walking shoes are essential, especially for exploring the trails. Light, breathable clothing is recommended due to the subtropical climate. A raincoat or waterproof jacket is advisable, as the mist from the falls can be significant, particularly near the Devil's Throat. Don't forget sunscreen, a hat, and insect repellent.
Entry to Iguaçu National Park requires a ticket, which can often be purchased online in advance or at the park entrance. It's advisable to check the official park website for the latest information on ticket prices, operating hours, and any specific entry requirements or regulations.
Beyond the spectacular waterfalls, the region is characterized by its lush subtropical rainforest, which is part of the Atlantic Forest biome. This ecosystem supports a wide variety of plant life, including diverse vascular plants, and contributes to the vibrant habitat for the region's wildlife.
