Iguaçu Falls is one of the world's largest waterfall systems, a chain of about 275 cascades stretching some 2.7 km along the Iguaçu River on the Brazil–Argentina border; Iguaçu National Park was inscribed as a UNESCO World Heritage Site in 1986. The Brazilian side, in Foz do Iguaçu (Paraná), is famous for its sweeping panoramic 'postcard' view of the whole falls and for the walkway that juts out toward the Devil's Throat (Garganta do Diabo). As of 2026 the national park is operating normally, with entry by date- and time-stamped online booking. Half a day covers the main Brazilian trails, so many travelers pair it with the more up-close Argentine side over two days.
Devil's Throat (Garganta do Diabo): the ~80 m signature cascade, faced head-on from a steel walkway that extends over the river into the roar and spray
Cataratas Trail (about 1.2 km): the classic Brazilian-side walk with the full panorama of the falls, with rainbows common in morning-to-midday sun
Porto Canoas viewing deck and riverside restaurant overlooking the calmer waters above the falls
Macuco Safari: an optional paid speedboat ride that pushes right under the cascades (expect to get soaked)
Add-on activities inside the park such as the Helisul helicopter flight and the Poço Preto eco-trail
Good to know
SafetyThe Iguaçu / Foz do Iguaçu region is a recommended yellow-fever vaccination area; ideally get vaccinated at least 10 days before travel and pack insect repellent.
SafetyAt the Devil's Throat walkway heavy spray will soak your clothes and electronics. Bring a poncho or waterproof pouch, wear closed non-slip shoes, and keep your phone in a waterproof case.
SeasonJuly is Southern Hemisphere winter (dry season): pleasant weather but relatively lower water volume, while December–February brings more water but hot, humid, crowded conditions. After heavy rain the Devil's Throat walkway can close temporarily, so check conditions before you go.
RulesTickets are booked online for a specific date and time slot; popular slots sell out in high season. Prices and hours change, so always confirm the latest details before visiting.
MannersCoatis (quatis) roam freely throughout the park, especially near Porto Canoas. Never feed them and don't carry exposed food—they will scratch or bite to grab a snack.
CautionBuy tickets only from the official website and avoid marked-up resellers or fake tickets. In Foz do Iguaçu and the Triple Frontier area, use official taxis or ride-hailing apps and watch for pickpocketing and inflated tour prices.

Admission includes the panoramic double-decker shuttle bus inside the park plus the Cataratas Trail and Devil's Throat viewpoint, while Macuco Safari, helicopter flights, and similar extras cost separately.
