Iguazu Falls

Iguazu Falls in South America is one of the world's five great waterfalls, known for its vast width. The name "Iguazu" means "great water" in the language of the Guarani, the indigenous people of South America. The falls are located on the border between Argentina and Brazil. In 1984, Iguazu Falls was designated a UNESCO World Natural Heritage site. What sets Iguazu Falls apart is the multitude of viewing points, offering different perspectives from various locations, directions, and heights. The entire waterfall system is vast in quantity, majestic in scale, and awe-inspiring in sound, creating an unforgettable experience. 1. Waterfall history In the 1540s, Spanish explorer Cabeza de Vaca wrote about it in European records when he traversed the rainforest. The formation of such a spectacular waterfall at Iguazu is inseparable from its geological and geographical conditions. The current terrain was shaped by volcanic eruptions 1.2 billion years ago. The Paraná River valley in Brazil consists of north-south trending basalt, while the Iguazu River and its bedrock run perpendicular to the Paraná River, resulting in much weaker erosion compared to the Paraná. Even today, the waterfall continues to change and will keep evolving. The transformation of what was once a basalt plateau into today's breathtaking landscape is truly awe-inspiring. 2. Waterfall details The Iguazu River originates in the Mar Mountains near Curitiba, winding westward through the Brazilian Highlands for 1,320 km. Before merging into the Paraná River, it collects over 30 tributaries along its course. At Iguazu Falls, the river widens to 4 km. Iguazu Falls is a spectacle whose power, form, and thunderous roar can only be believed after experiencing it firsthand. Under the sunlight, it creates countless fantastical rainbows, presenting a magnificent sight. Iguazu Falls far surpasses Niagara Falls in North America in both height and width, offering a more majestic and splendid view. Its roaring waters can be heard from 30 km away, making it a true wonder of the world. Located in a subtropical region, Iguazu Falls maintains relatively stable water levels throughout the year. The local rainy season from January to March brings the highest water flow, making it the best time to visit, while the dry season from August to October sees reduced water volume. 3. Devil's throat Nearly half the water of the Iguazu River squeezes into this U-shaped crack, tumbling down to the valley floor over 80 m below, roaring like rolling thunder, with mist rising dozens of meters high. On sunny days, rainbows almost hang over the curtain of mist all day long. 4. In-park activities A few years ago, Iguazu Falls was operated by a private company, which built about 20 km of sightseeing boardwalks, laid an electric railway, and completely upgraded the tourism facilities. Within the attraction, visitors can walk along the boardwalks or take a sightseeing train to explore various attractions. At the end of the boardwalk, there is a tower where an elevator takes you directly to the top of the falls for a side view of Iguazu Falls. Getting up close to the waterfalls is one of the most thrilling activities in Iguazu – riding a speedboat into the falls and weaving through them is incredibly exhilarating. However, this is an optional activity (fees excluded) costing $60 per ride, and requires going downstream first. First, take a sightseeing vehicle through the jungle (it's said that the seeds of a certain tree along the way are exclusively used for French perfumes, while some plants serve as staple food for indigenous people). After disembarking, transfer to a jeep to descend several steep slopes before reaching the speedboat departure point. Travelers need to wear raincoats and life jackets before boarding the speedboat. The boat moves upstream at a relatively fast speed, with rapid currents. When approaching the waterfalls, the boat stops to allow travelers to take photos, then revs up and charges straight toward the falls. This is repeated several times, making it an extremely thrilling experience. 5. Differences between touring Argentina and Brazil The waterfalls are distributed on both sides of the canyon, which serves as the border between Argentina and Brazil, offering strikingly different views from each country. The park on the Brazilian side is one of Brazil's larger forest reserves, covering 170,000 hectares and home to abundant wildlife. In Argentina, there are two tour routes: the lower path winds through dense forests, allowing you to admire the grandeur or charm of each waterfall section from below—truly a new view every ten steps. The upper path offers a top-down experience of the waterfalls' cascading power. On the Brazilian side, you can enjoy a panoramic view of the main waterfalls in Argentina.Iguazu · 24.9 km from Foz do Iguacu

We had a truly amazing time at Iguacu National Park. The park is well organized, the staff are friendly and the routes are well maintained. There is a great lookout point where you are right above some of the falls and you get completely wet! This was one of those experiences that will flash before my eyes just before I die.

When traveling to Brazil🇧🇷 and Argentina🇦🇷 in South America, the Iguazu Falls at the border of the two countries is a must-see attraction. In addition, the Iguazu Bird Park is also a recommended attraction. The bird park has birds unique to South America, including hornbills with beaks like big bananas, flamingos behind pink flocks, and the most eye-catching is the macaw, which has bright colors and reminds people of the fiery character of the South American people.

If the weather is good, there will be many rainbows🌈, and the scenery is beautiful. Especially at the Devil's Throat attraction, there will be rainbows crossing above, below, left and right🌈, and people will walk in the rainbow🌈🌈.

The Devil's Throat in Argentina is the most stunning chapter of the Iguazu Falls. The surging water is like a galloping horse, falling into the abyss with the force of thunder, and the rainbow is looming in the steaming water. The roar resounds through the valley, and the majestic momentum hits the soul directly, showing the wild beauty of nature's uncanny craftsmanship.
