Advance permission from the National Park Department (IBAMA) is advisable for visiting this park (there are no tourist facilities), but hard-core nature lovers will find that it's an excellent place to see Brazilian wildlife. The residents include rheas, anteaters, capybaras, coatimundis and armadillos, as well as tropical birds. Enormous termite mounds dot the grounds. The park lies east of the Pantanal. 745 mi/1,200 km northwest of Rio de Janeiro.
