Pantanal

It is the largest wetland in the world, located in the heart of South America.  It covers 81,081 square miles (210,000 sq km).  In Brazil, the majority are divided between the provinces of Mato Grosso and Mato Grosso do Sul.  These open marshes are home to huge numbers of species.  If you like to see animals in the natural environment, Pantanal is an unmissable destination.
There are few people in Pantanal and no cities.  Its distances are small, and land transport is so poor that people move around in small planes and motorboats.  Car traffic is restricted here.
You can either cross the Pantanal from the north.  It runs deep into the Transpontanera region.  Or cut across the Estrada Park wetlands to the south.  The road that was most likely to cross the Pantanal has been closed for a long time due to concerns about having a road submerged for half a year.
