Iguazu Falls
Nearly 3 km of waterfalls on the Argentina–Brazil border: catwalks over the Devil's Throat, spray, rainbows and subtropical forest all around.
What it is
Iguazu is a system of about 275 waterfalls on the river of the same name, on the border between Argentina and Brazil. The most powerful section is the Devil's Throat (Garganta del Diablo), a horseshoe-shaped chasm where the water drops about 80 m and much of the river's flow pours in. The national parks on both sides are UNESCO World Heritage sites.
When and how
Most of the falls are on the Argentine side: the Upper and Lower trails run right above and below the cascades, and the Jungle Train and about a kilometer of catwalks lead to the Devil's Throat. The Brazilian side has the big panorama and needs half a day. The falls are good year-round; December to February is hot, humid and crowded, and water levels depend on rain.
Tip
Arrive at opening time and go to the Devil's Throat first, before the crowds. Keep food away from the coatis: they are skilled at raiding backpacks and can bite.
