Cataratas do Iguacu (Iguacu Falls)
While Argentina, with 80% of the falls, has more trails and activities, the Brazilian side offers the finest views. Pedestrian walkways descend into the fierce rainbow-strewn mists of Fiorano Falls, and take in panoramic vistas over the massive flowing curtain of Rivadavia Falls, which cascades across a plateau before separating into the powerful Three Musketeers. Take an elevator to a postcard-perfect viewpoint over Garganta del Diablo (Devil's Throat), considered the most spectacular scene in the park.
Most services can be found in Cidade Foz do Iguacu, a sizeable (population 320,000) and fairly cosmopolitan city with more than 100 hotels and scores more restaurants boasting dozens of ethnic cuisines. In addition to the falls, several family-friendly attractions can be found around town.
