Iguazu Falls Trail & Visitor Guide
Iguazu Falls · Argentina · The waterfall system spans roughly 2.7 km along the Iguazu River and consists of about 275 individual cascades and drops, with the tallest (Devil's Throat) falling around 80 m. The Argentine park covers about 67,000 ha and the Brazilian park about 185,000 ha.
Why Visit Iguazu Falls
Iguazu Falls is a system of 275 waterfalls along the Iguazu River at the Argentina-Brazil border, stretching nearly 1.7 miles wide. The tallest drop, Devil's Throat, plunges 269 feet in a horseshoe-shaped chasm where the force of water creates a permanent cloud of mist. The falls sit within 550,000 acres of Atlantic Forest, home to toucans, coatis, and over 2,000 plant species. Eleanor Roosevelt reportedly exclaimed 'Poor Niagara!' upon seeing them.

Wildlife You May See
Entrance Fee
Argentine side (Parque Nacional Iguazú): foreign-visitor ticket about ARS 45,000 in 2025 (priced in pesos and subject to frequent change with inflation); pay in cash pesos or card at the gate. Brazilian side (Parque Nacional do Iguaçu): foreign-visitor ticket about BRL 100-110 in 2025, bought online in advance at cataratasdoiguacu.com.br. Each side is a separate ticket and a separate country.
Getting There
The two gateway cities are Puerto Iguazú, Argentina, and Foz do Iguaçu, Brazil, on opposite banks of the Iguazu River. Both have airports with daily flights (Argentina: IGR, about 1.5-2 hrs from Buenos Aires; Brazil: IGU, about 2 hrs from São Paulo or Rio). From Puerto Iguazú the park is about 18 km; take the Río Uruguay bus line or a taxi (~20-30 min). From Foz do Iguaçu the park entrance is about 17 km via city bus line 120 from the Terminal de Transporte Urbano. Crossing between the two sides means an international border crossing over the Tancredo Neves Bridge; carry your passport and confirm visa rules for your nationality before crossing.
Where to Stay
Inside the parks: the Gran Meliá Iguazú (Argentine side, formerly Sheraton) and the Hotel das Cataratas (Belmond, Brazilian side) are the only on-site hotels and let you reach the falls before and after day-trip crowds. Budget and mid-range options cluster in Puerto Iguazú town (Argentina) and Foz do Iguaçu (Brazil); Foz has the larger selection. Most visitors base in one town and day-trip to both sides over two days.
Best Time
The falls flow year-round. Water volume peaks in the wet season (roughly December-March), which also brings the hottest, most humid weather and possible flood closures. April-June and September-November offer milder temperatures and generally good flow. Go early in the day to beat tour-bus crowds.
Safety
The top hazard is the river itself: wet, slick catwalks and powerful currents at the rim mean staying behind railings is non-negotiable, especially at Devil's Throat. After heavy rain the river can flood and the Garganta del Diablo catwalk, San Martín Island and boat tours close without notice. Coatis bite and scratch when people feed them or leave food open, and can transmit disease, so keep food sealed. The region is subtropical with dengue-carrying mosquitoes, so use repellent. Sun and humidity are intense; carry water. Spray will soak you and electronics at the main viewpoints, so bring a dry bag.
