Iguazu Falls, the largest waterfalls system in the world, are truly awe-inspiring to behold, spanning the border between Brazil and Argentina. Though Brazil boasts better views of the falls, Argentina is blessed with about 80 percent of this natural marvel’s 275 separate cascades. Paved trails and catwalks wind their way around the falls—sometimes reaching within an arm’s length of the water—and a free train connects the main trailheads.
The best way to experience the Argentinean side of Iguazu Falls is by hiking the surrounding trails. The Upper Circuit Trail offers outstanding views over Mbigua Falls and the Iguazu River before dropping toward the Bernabe Mendez Falls. The Lower Circuit Trail has more viewpoints, as well as access to activities such as boat trips, white-water rafting, and a free ferry to Isla San Martin. A guided tour will help you find the best trails and can take you deeper into Iguazu National Park, or on ATV tours and hiking excursions in the area.
The park’s entry fee includes unlimited rides on the Jungle Train to different trailheads, as well as ferry service (depending on the water level) to Isla Martin. You can visit the park a second day for half price; be sure to get your ticket stamped after the first day.
Things to Know Before You Go
Plan to spend at least one full day exploring this side of the falls.
Regardless of which trail you take, prepare to get soaked: Wear waterproof clothing, and protect your valuables and electronics with waterproof bags.
The Argentinean side is known for its hiking and opportunities to get closer to the cascades.
Don’t miss the spectacular vistas over Devil’s Throat (Garganta del Diablo).
Many guided tours take you to both the Argentinean and Brazilian sides of the falls.
If crossing the border without joining a guided tour, be sure to check visa requirements for your country.
How to Get There
Iguazu National Park is located 10 miles (17 kilometers) from Puerto Iguazu. Buses run from Puerto Iguazu to the park every half hour during park hours. If you're coming from Buenos Aires, take a 90-minute flight or a 24-hour bus ride.
When to Get There
Iguazu Falls is accessible year-round. For the best weather and the smallest crowds, plan to go between July and October or February and April. Morning visits reward with rainbows in the ever-present mist of Devil’s Throat.
Experiencing Devil’s Throat
Devil’s Throat, whose 14 thundering cascades comprise the tallest and most famous part of Iguazu Falls, is best viewed from the Devil’s Throat Walk, which takes you right up to the brink of the water. If that’s not close enough, you can also take a boat ride that glides right under the falls.
