Parque Nacional Iguazu (Iguazu National Park)

Though the Brazilians boast of their outstanding views over the falls, Argentina is blessed with about 80% of Iguazu, lovingly threaded by several kilometers of paved trails and catwalks that could keep you occupied for three days. A free "jungle train" connects several trailheads.

The Upper Circuit Trail offers outstanding views over Mbigua Falls and the undulating Iguazu River, before dropping toward misty Bernabe Mendez Falls. The Lower Circuit Trail has more views, as well as access to motorboat trips under the falls, whitewater rafting, and a free ferry to Isla San Martin, with even more to explore. Whatever you do, don't miss the vistas over Garganta del Diablo.

No matter where you trek, you will get soaking wet. And that's not a bad thing on a hot summer day in Argentina.

Though Puerto Iguazu, 17km (10mi) from the park, is the smallest of the three cities here at the triple border between Brazil, Paraguay, and Argentina, it has a great deal to offer tourists. A wide range of hotels and restaurants cater to travelers of every sort (and prices are generally lower here than Brazil), and several family-friendly attractions are easy to visit from the falls.

Practical Info

Buses run from Puerto Iguazu every half hour during park hours. The 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.
