The Litoral is the wet corner of Argentina: the land between the Paraná and Uruguay rivers, running north-east into subtropical Misiones where the soil turns iron red and the forest closes in. It takes in Entre Ríos, Corrientes, Misiones, Santa Fe, Chaco and Formosa, and it has more water than the rest of the country put together.
Iguazú Falls is the thing everyone comes for, and it deserves the trip — 275 separate cataracts spread across nearly three kilometres of jungle, with the Garganta del Diablo at the centre of it. Puerto Iguazú is the town you sleep in.
The Iberá Wetlands are the region's quieter case: thirteen thousand square kilometres of marsh in Corrientes, now the site of the most ambitious rewilding project in South America, with jaguars, giant anteaters and macaws returned to country they had been absent from for decades. Capybara and caiman are guaranteed.
Rosario on the Paraná is the region's real city — birthplace of the flag and of Che Guevara, with a riverfront Argentines rate above Buenos Aires's. Summers here are genuinely hot and humid; the shoulder months are kinder.
