Iguazu Falls — 3-Day Itinerary
Eleanor Roosevelt reportedly exclaimed poor Niagara upon seeing Iguazu Falls. The comparison is apt: Iguazu is wider, taller in places, and surrounded by subtropical jungle rather than casinos. Three days covers both the Argentine and Brazilian sides of this UNESCO wonder, each offering dramatically different perspectives.
Argentine Side: Upper & Lower Circuits
Morning: Enter the Argentine side of Iguazu National Park (ARS $12,000, keep your ticket for a discounted second-day visit). Take the ecological train to Estacion Cataratas and walk the Upper Circuit (1.7 km), a series of walkways above the falls looking down into the cascades. The perspective from above reveals the full scope: 275 individual falls across nearly 3 km of the Iguazu River. Continue to the Lower Circuit (1.4 km) which descends to the base of the falls where the spray soaks you and the roar is deafening. Salto Bosetti is a highlight.
Afternoon: Take the free boat across to San Martin Island for the most intimate waterfall views. The island sits in the middle of the falls system with trails leading to swimming areas (when water levels permit) and viewpoints that put you between cascading walls of water on three sides. The climb up the rocky trail is worth the effort. Lunch at the park restaurant La Selva (ARS $4,000-8,000) or pack a picnic. Coatis (raccoon-like mammals) patrol the paths looking for food; they are bold and persistent so keep bags closed.
Evening: Afternoon optional: the Great Adventure boat ride (ARS $15,000) motors upstream through rapids and directly under the falls, delivering a complete soaking that is half exhilarating and half terrifying. Waterproof bags for electronics are essential. Return to Puerto Iguazu town (20 km from the park) for dinner at La Rueda (ARS $4,000-8,000) for river fish surubi grilled on the parrilla, or Aqva (ARS $6,000-12,000) for refined cuisine using Misiones province ingredients like yerba mate, tropical fruit, and freshwater fish.
Devil Throat & Brazilian Side
Morning: Return to the Argentine park early morning for the Devil Throat (Garganta del Diablo), the most powerful single section of Iguazu Falls. Take the ecological train to the Estacion Garganta and walk the 1.1 km boardwalk across the Upper Iguazu River to the brink of the U-shaped falls. The walkway ends at a platform directly above the 82-meter drop where 1,750 cubic meters of water per second plunge into a perpetual cloud of mist and rainbow. The sound and power at this viewpoint are overwhelming. Arrive by 8 AM for the clearest views before mist intensifies.
Afternoon: Cross to the Brazilian side (passport required, Brazilian park entry BRL $85 roughly $17). The Brazilian side provides the panoramic overview that the Argentine side cannot. A single 1.2 km trail follows the canyon rim with viewpoints encompassing the entire falls system. The perspective from this side reveals why Iguazu is considered the most beautiful waterfall on earth: the panorama of hundreds of cascades pouring over a curved basalt cliff into a jungle canyon is simply staggering. The final walkway extends into the spray at the base of the Devil Throat.
Evening: The Brazilian side takes 2-3 hours including the elevator and boardwalk at the falls base. Visit the Parque das Aves (BRL $75), a bird park beside the Brazilian park entrance housing toucans, macaws, flamingos, and other South American birds in large walk-through aviaries. The scarlet macaw aviary where the birds fly freely around you is memorable. Return to Puerto Iguazu for evening. Dinner at El Quincho del Tio Querido (ARS $5,000-10,000) for an Argentine-Brazilian-Paraguayan crossroads meal featuring surubi fish, empanadas, and chipa (cheese bread).
Triple Border, Jungle Trails & Farewell
Morning: Visit the Hito Tres Fronteras viewpoint in Puerto Iguazu where Argentina, Brazil, and Paraguay meet at the confluence of the Iguazu and Parana rivers. Each country has its own viewpoint with flags and markers. The Paraguayan city of Ciudad del Este is visible across the river, famous for its chaotic electronics market. Optional: cross to the Brazilian side to visit Foz do Iguacu and the Itaipu Dam (BRL $120 tour), the world second-largest hydroelectric dam producing 75 percent of Paraguay electricity and 15 percent of Brazil electricity.
Afternoon: Return to the Argentine park for the Sendero Macuco trail (7 km round trip, easy to moderate), a quieter jungle walk to a hidden waterfall away from the main falls. The trail passes through primary subtropical forest with opportunities to spot monkeys, toucans, and giant butterflies without the crowds of the main circuits. The Salto Arrechea at the trail end is a 20-meter waterfall in a jungle grotto with a natural swimming pool. This trail shows the ecosystem that supports the falls: 2,000 plant species and 450 bird species.
Evening: Farewell afternoon from the Devil Throat platform one final time if you purchased the two-day ticket. The falls change character with the light, and afternoon sun creates different rainbow patterns than morning. Alternatively, hire a boat for a sunset cruise on the Upper Iguazu River (ARS $10,000-15,000) above the falls where the river is calm and wide. Final dinner at Puerto Bamboo (ARS $5,000-10,000) for river fish and Argentine wine on a terrace overlooking the Iguazu River. The jungle sounds at dusk provide a natural soundtrack for your farewell.

Seasonal Highlights at Iguazu Falls
Iguazu Falls changes dramatically with the seasons, and when you visit shapes everything from the volume and drama of the cascades to the wildlife you encounter and the temperatures you tolerate. There is no definitively bad time to come, but each season offers a distinctly different experience worth understanding before you book.
The rainy season from October through March brings the highest water volumes. The Iguazu River swells with rainfall across the watershed in Brazil and Argentina, and the falls reach their most powerful and violent state. The Devil Throat churns with extraordinary force — the mist column rises 30 metres above the falls and is visible from Puerto Iguazu town on the clearest days. The falls' colour shifts from blue-green to a churning red-brown during peak flow as the river carries sediment from upstream. The downside: higher water sometimes submerges the lower boardwalks entirely, closing the Lower Circuit and portions of the Brazilian trail for days or weeks. January and February are the hottest months at 35-40°C with high humidity. Pack light, start early, and drink water constantly.
April and May represent the best overall balance. Rainy season winds down, water levels remain high but boardwalks are reliably open, temperatures drop to a more comfortable 22-28°C, and regional visitor numbers fall sharply as Brazilian school holidays end. The jungle is intensely green from recent rains and wildlife activity peaks — coatis, toucans, and capibaras are visible on virtually every trail section. These two months are the least crowded of any period with reasonable water volume.
June through August is dry season and Argentine winter. Temperatures in the park drop to 15-22°C during the day and occasionally to single digits at night — cool and pleasant for walking, though the falls lose some of their raw drama as volumes decrease by 30-50 percent compared to wet season peaks. The payoff is extraordinary visibility: the mist that often obscures the falls at their most powerful clears in dry season, and on sunny winter mornings the view from both circuits is crisper than at any other time. Hotel rates in Puerto Iguazu and Foz do Iguacu drop 20-30 percent, and the parks are noticeably quieter.
September brings the first spring wildflowers into the park's forest edges and is considered by many naturalists the best month for birdwatching. The 450 recorded bird species of Iguazu National Park include toucans, parrots, hummingbirds, and the great dusky swift, which nests behind the falls themselves. September mornings see large flocks of swifts flying into the mist at Devil Throat — a spectacle that draws wildlife photographers from across South America. Water levels begin rising again through October, and the full rainy season cycle repeats.
