Iguazu Falls stretch across nearly 2.7 km at the border between Argentina and Brazil, in the province of Misiones. The Argentine side, managed by Iguazu National Park (UNESCO World Heritage site), offers an immersive experience at the heart of the falls: walkways skimming the water, dense subtropical jungle and the Garganta del Diablo as its crowning point. It is one of the most vast waterfall systems on the planet.

Practical Information at a Glance

• Entrance: paid admission (fee in Argentine pesos, varies by season and nationality — check with the park or your local agency).
• Recommended duration: a full day to explore the two main circuits.
• Dress code: closed, non-slip footwear strongly recommended; waterproof clothing advisable near Garganta del Diablo.
• Access: from Puerto Iguazú, regular buses to the park entrance. Puerto Iguazú international airport (IGR) approximately 20 km away.
• Wheelchair accessibility: the Lower Circuit and Garganta del Diablo walkway are largely wheelchair-accessible; electric carts are available within the park.
• Wildlife: wild coatis present — do not feed them.

What to See

The Argentine park features approximately 275 individual falls distributed across two marked trails. The vegetation is subtropical Atlantic forest: tree ferns, orchids, toucans, herons and blue morpho butterflies. Metal walkways overhang the cascades directly, sometimes just a few meters from the waterfall's edge.

History and Context

The name "Iguazú" comes from the Guaraní y (water) and guasu (great). The Guaraní peoples inhabited the region long before the arrival of Spanish conquistadors in the 16th century. The Argentine national park was created in 1934; it has been inscribed as a UNESCO World Heritage site since 1984. On the Brazilian side, the Iguaçu National Park received the same distinction in 1986.

Highlights of Your Visit

Garganta del Diablo

This is the highest and most powerful fall in the system: approximately 82 meters in height, with a flow that can exceed 6,000 m³/s during the rainy season. A 1,100-meter walkway leads to a viewing platform suspended above the gorge. Spray is constant; bring a waterproof cover for your camera.

Lower Circuit

This trail descends to the level of the Lower Iguazu River and runs along the base of the falls. Proximity to the water is at its maximum. It is the most accessible circuit and most photographed in morning light.

Upper Circuit

The walkways overhang the falls from above, offering a panoramic perspective over the entire system and the forest below. Ideal in late afternoon for raking light.

Boat Ride Under the Falls (Aventura Náutica)

Zodiac excursions depart from the lower bank and approach directly beneath the cascades. You will get soaked — that's the point. Reservations possible on-site or through your agency.

Photography Tips

Morning light (at park opening) illuminates the Lower Circuit head-on. For Garganta del Diablo, afternoon offers dramatic backlighting but spray remains intense. A polarizing filter reduces reflections on the water. Protect your gear: humidity is constant within 50 meters of the main falls. Drones are prohibited in the park.

Location and Access

Iguazu National Park is located approximately 20 km southeast of Puerto Iguazú, an Argentine city at the triple border with Brazil and Paraguay. Cataratas del Iguazú International Airport (IGR) serves Buenos Aires (frequent direct flights) and São Paulo. From Puerto Iguazú, public buses regularly connect to the park entrance. Private shuttles are available through hotels and local agencies.

The Brazilian side (Foz do Iguaçu) is accessible by crossing the international bridge; a visa or authorization may be required depending on your nationality — verify before departure.
