Iguazú Falls
The Argentine Side — In the Midst Instead of Just There★★★
★★★ Cataratas del Iguazú — Argentine Side
The Iguazú Falls (Guaraní: "Yguazú" = Great Water) on the border between Argentina and Brazil are one of the most powerful natural spectacles on Earth: 275 individual cascades plunge over a width of 2.7 km up to 82 meters deep. They are wider than Niagara Falls (which are only 1.2 km wide), higher than Victoria Falls (which are 55 m high), and more spectacular than both combined. UNESCO World Natural Heritage since 1984.
The Guaraní legend tells: The god M-Boí transformed into a giant snake and bent the river when a beautiful woman spurned him — thus the falls were created. The reality is geologically less romantic (basalt layers of varying hardness), but the result is the same: overwhelming.
The Argentine side is the more intense experience: A system of walkways leads you directly over and beside the falls — you feel the mist on your face, the air vibrates, and the roar of the water is deafening. Plan at least a full day (better two, to also visit the Brazilian side).
Parque Nacional Iguazú. Entrance: approx. 20,000 ARS (approx. 15€, foreigner price, 50% discount on the second day — stamp on the ticket!). Daily 8:00–18:00 (last entry 16:30). Parking: approx. 3,000 ARS.
Garganta del Diablo — The Devil's Throat
★★★ Circuito Garganta del Diablo — THE Highlight
The Garganta del Diablo (Devil's Throat) is the centerpiece of Iguazú and the most powerful of the 275 falls. Here, 14 waterfalls simultaneously plunge into a 150 m wide, 82 m deep horseshoe-shaped basin — the mist rises 30 meters high, the rainbow is permanent (in sunshine), and the roar is so loud that you have to shout to be heard. The water volume: Up to 6,500 cubic meters per second in the rainy season — enough to fill Lake Constance in 23 days.
Access is via a 1.1 km long walkway over the Río Iguazú Superior — you walk over the calm, dark water of the river, past butterflies and toucans in the jungle on the left and right, and then suddenly: The abyss opens up. You stand at the edge of the brink, below you the water thunders into the depths, the mist envelops you, and you cannot see the bottom of the basin — only a cloud of water and rainbows. It is overwhelming, humbling, and exhilarating all at once.
You will get WET! Not a little, but completely soaked. Bring:
- Waterproof phone case (mandatory! The mist ruins unprotected electronics)
- Rain poncho (available in the park, approx. 2,000 ARS)
- Leave change of clothes in the locker at the park entrance
- Camera in a Ziplock bag
Access via Tren de la Selva (free park train, 25 min.) to Estación Garganta del Diablo. First train: 8:30, last return train: 16:30. TIP: Take the first train! The tour groups arrive from 10 a.m., and the queue for the train can be 30–60 minutes at noon.
Circuito Superior & Inferior
★★★ Circuito Superior (Upper Circuit)
1.7 km of walkways above the falls: You look down on the cascades from above and see how the water plunges over the edge into the depths. The view of Salto San Martín, Salto Mbiguá, and Salto Bernabé Méndez is magnificent — you stand directly above the edge of the falls! Less wet than the lower path (but still misty). The view of the Garganta del Diablo from afar is spectacular. Duration: approx. 1–1.5h.
★★★ Circuito Inferior (Lower Circuit)
1.7 km of walkways and stairs that lead you to the foot of the falls. You stand in front of the wall of water and look up — the falls thunder above you, the mist rains down on you, and the sheer power of the water is humbling. At Salto Bossetti you stand so close that you feel the wind of the falling water masses. At Salto San Martín — the second largest fall after the Garganta — the path goes almost to the foot.
From here, the boat crossing to Isla San Martín starts (open only at low water levels, free): The small island in the middle of the falls offers a unique view from WITHIN the falls system — cascades plunge down on both sides. If open: definitely go across!
★★★ Gran Aventura — The Speedboat Under the Falls
The most adrenaline-pumping experience in Iguazú: A speedboat (Zodiac) first takes you up the Río Iguazú Inferior through the jungle (caimans on the shore!), then directly under the waterfalls! The boat rides into the mist of Salto San Martín — the water crashes down on you, you scream with excitement, and everyone in the boat is completely soaked. The boat turns around, goes back in. And again. Absolutely recommended!
Approx. 30,000–50,000 ARS (25–40€). Several departures daily (from Circuito Inferior or Estación Cataratas). Store everything in waterproof bags! Smartphones will get wet. Duration: approx. 12 min. on the water, total approx. 1h including jungle truck ride.
Full Moon Tour & Tips
★★★ Paseo de Luna Llena — Full Moon Tour
Perhaps the most magical experience Iguazú has to offer — and one that few know about: On five nights per month (around the full moon), the national park offers a night hike to the Garganta del Diablo in the moonlight. You walk over the walkways in the darkness, the waterfalls thunder invisibly beside you, the moonlight illuminates the mist in a silvery glow, and — if everything aligns — a moonbow (lunar rainbow) appears over the Devil's Throat. A goosebump moment.
Only on 5 nights/month at full moon. Tickets very limited (max. 120 people/night) — book weeks in advance via iguazuargentina.com! Approx. 30,000 ARS. Departure 20:00 from the park entrance, return around 23:00. Tren de la Selva also runs at night.
Optimal Daily Schedule — How to Do It Right
| Time | Activity |
|---|---|
| 8:00 | Park entrance, directly to Tren de la Selva → Garganta del Diablo (take the first train!) |
| 8:30–10:30 | Garganta del Diablo — stay there for at least 30 min., watch the water |
| 10:30–12:00 | Return by train, then Circuito Superior |
| 12:00–13:00 | Lunch at the park café or brought snacks (food in the park is expensive!) |
| 13:00–15:00 | Circuito Inferior + Isla San Martín (if open) |
| 15:00–16:00 | Gran Aventura boat tour (fetch change of clothes beforehand!) |
| 16:00–17:00 | Sendero Macuco (optional jungle trail, 7 km, toucans + coatis) |
Wildlife Encounters in the Park
The national park protects subtropical Atlantic rainforest and is full of wildlife:
- Coatis: Everywhere! The cheeky snouted animals roam the park and steal food from bags. Do not feed! (They become aggressive and bite — seriously)
- Toucans: The colorful birds with the huge beak are the symbol of Iguazú. Best seen early in the morning
- Butterflies: Hundreds of species — Iguazú is a butterfly paradise. Especially after rain
- Caimans: In the Río Iguazú Inferior, well visible from the Gran-Aventura boat tour
- Monkeys (Howler monkeys): Audible in the jungle, visible with luck
- Jaguar: Extremely rare, but they live here. The chance of seeing one: virtually zero
Tipp
Arrive directly at 8:00 a.m. for park opening and go FIRST to the Garganta del Diablo (take the first train!) — the large tour groups don't arrive until after 10 a.m. In the afternoon, the two circuits and Gran Aventura. Bring a rain poncho, waterproof phone case, and change of clothes — you WILL get wet! Don't forget mosquito spray (subtropical!). And: Wear sturdy shoes — the walkways can be slippery.
Brazilian Side, San Ignacio Miní & Puerto Iguazú
★★★ Brazilian Side — The Panorama
The Brazilian side offers what the Argentine side lacks: the panoramic view of the entire edge of the falls. You see all 275 cascades at once — a breathtaking widescreen natural cinema stretching over 2.7 km. If the Argentine side is the "in the midst," then the Brazilian side is the "overview."
A 1.5 km long panoramic trail runs along the gorge with various viewpoints. At the end: A walkway that juts directly into the mist of the Garganta del Diablo — the most dramatic position on the Brazilian side (you will get WET). The panoramic view from above of the entire falls system is the best photo you can take at Iguazú.
Argentine vs. Brazilian — The Comparison
| Aspect | Argentine Side | Brazilian Side |
|---|---|---|
| Experience | In the midst, up close, intense | Panorama, overview, photographic |
| Wetness Level | Completely soaked | Moderate to wet (walkway at the end) |
| Duration | Full day (6–8h) | Half day (2–3h is enough) |
| Walkways/Trails | Three circuits + boat | One panoramic trail |
| Garganta del Diablo | From above at the edge | From the side, walkway into the mist |
| Wildlife | More (larger park) | Less, but bird park next door |
| Recommendation | MUST-SEE (Day 1) | Highly recommended (Day 2, half day) |
Border Crossing: As an EU citizen no visa for Brazil is required (up to 90 days). Bring your passport! Buses run regularly from Puerto Iguazú (AR) to Foz do Iguaçu (BR) over the international bridge (approx. 30 min., 2,000 ARS). Taxi/Uber also possible (approx. 8,000 ARS). Note: Time change — Brazil is 1 hour ahead of Argentina!
★★ Ruinas de San Ignacio Miní — The Jesuit Reductions
The best-preserved Jesuit reductions in Argentina (UNESCO World Heritage) are located 250 km southwest of Iguazú. In the 17th and 18th centuries, the Jesuits built a unique social utopia here: settlements for the indigenous Guaraní with their own administration, schools, workshops, and one of the most advanced societies of their time — while Spanish colonial rulers enslaved the indigenous people elsewhere.
The ruins of the reduction are impressive: The church (with elaborate stone carvings by the Guaraní), the workshops, the houses, and the plaza are partially reconstructed, partially overgrown by jungle — an atmospheric mix of Angkor Wat and European mission architecture. Known from the film "The Mission" (1986) with Robert De Niro and Jeremy Irons.
240 km from Puerto Iguazú (3h by car or bus). Entrance: approx. 5,000 ARS (approx. 4€). Daily 7:00–18:00. In the evening: impressive light and sound show (approx. 10,000 ARS, 20:00). Possible as a day tour from Puerto Iguazú — worth it if you have a third day!
★★ Hito Tres Fronteras (Three Borders Landmark)
At the confluence of the Río Iguazú and Río Paraná, three countries meet: Argentina, Brazil, and Paraguay. From the viewpoint in Puerto Iguazú (Av. Tres Fronteras), you can see the Brazilian and Paraguayan flags waving on the other side. Each country has its own viewpoint with a flag and monument. The Argentine one is the most beautiful — especially at sunset, when the sky turns red over three countries simultaneously.
3 km from the center of Puerto Iguazú. Free entry. Taxi approx. 2,000 ARS. Best to come at sunset.
