Iguassu Falls, also known as Iguaçu Falls (Portuguese) or Iguazú Falls (Spanish), is one of the most spectacular natural wonders in the world. Located on the border between Brazil and Argentina, it stretches over 2.7 kilometers with a collection of more than 275 individual waterfalls. The falls are part of the Iguassu River and are surrounded by lush subtropical rainforest, offering breathtaking scenery and an unforgettable experience.
The Brazilian side of the falls is located in the state of Paraná, inside the Iguaçu National Park (Parque Nacional do Iguaçu), which is a UNESCO World Heritage Site. This area offers panoramic views and is well-known for its walkways and observation platforms that allow visitors to get very close to the mighty waterfalls.
Iguassu Falls can be accessed easily from both Brazil and Argentina. The nearest Brazilian city is Foz do Iguaçu, which has an international airport (Foz do Iguaçu International Airport - IGU) connected to major Brazilian cities like Rio de Janeiro, São Paulo, and Brasília.
From the airport, the falls are around 15-20 minutes away by car or taxi. Public buses and tour services also operate frequently to the national park. If coming from the Argentinian side, visitors can reach Puerto Iguazú and cross the Tancredo Neves Bridge to enter Brazil. International visitors may need a visa depending on their nationality.
Iguassu Falls enjoys a humid subtropical climate, with hot summers and mild winters. The average temperature ranges between 20°C to 32°C (68°F to 90°F) during summer months (December to March), and 10°C to 25°C (50°F to 77°F) during winter (June to August).
Rainfall is evenly distributed throughout the year, which keeps the waterfalls flowing continuously. However, the months of November to March usually have higher water volumes due to more rainfall. Visitors should bring light clothes, comfortable shoes, sunblock, and a rain poncho or waterproof jacket.
The Brazilian side of Iguassu Falls (Iguaçu National Park) is open every day, including holidays. The general opening hours are from 9:00 AM to 5:00 PM. Last entrance is allowed at 4:00 PM.
It’s recommended to arrive early in the day to make the most of your visit and to avoid large crowds, especially during peak season (December to February).
Iguassu Falls is famous for its sheer size and power. The falls are taller than Niagara Falls and nearly twice as wide. The most dramatic section is called "Devil’s Throat" (Garganta do Diabo), a U-shaped cascade that drops about 82 meters (269 feet).
The combination of roaring water, misty spray, rainbow arches, and surrounding jungle creates an awe-inspiring sight. It's also recognized for its rich biodiversity, as the national park is home to toucans, jaguars, butterflies, coatis, and hundreds of bird and plant species.
Tickets for the Brazilian side of Iguassu Falls can be purchased online or at the entrance. As of 2025, the ticket prices for international tourists are approximately R$84 (Brazilian Reais), with discounts for children, seniors, and Brazilian citizens.
Entry includes access to shuttle buses that take visitors from the entrance to key points in the park. The main trail offers various viewpoints and ends near the Devil’s Throat observation platform. Boat rides, helicopter tours, and eco-adventure trails are also available at an extra cost.
The area around Iguassu Falls was originally inhabited by the Guarani people. The falls were first discovered by Europeans in 1541, when Spanish explorer Álvar Núñez Cabeza de Vaca came across them. The name “Iguassu” comes from the indigenous Guarani language, meaning "big water".
In terms of infrastructure, Brazil has developed visitor-friendly facilities such as walking paths, bridges, rest areas, and viewing decks with minimal impact on the natural environment. The park is well-maintained and includes interpretive centers and museums explaining the ecosystem and history.
